Embracing Open Finance Innovation with MongoDB
The term "open finance" is increasingly a topic of discussion among banks, fintechs, and other financial services providers—and for good reason. Open finance, as the next stage of open banking, expands the scope of data sharing beyond traditional banking to include investments, insurance, pension funds, and more. To deliver these enhanced capabilities, financial service providers need a versatile and flexible data store that can seamlessly manage a wide array of financial data. MongoDB serves as an ideal solution, providing a unified data platform that empowers financial services providers to integrate various data sources, enabling real-time analytics, efficient data retrieval, and scalability. These capabilities are pivotal in enhancing customer experiences, providing users with a comprehensive view of their finances, and empowering them with greater visibility and control over their own data. By adopting MongoDB, financial services can seamlessly adapt to the growing demands of open finance and deliver innovative, data-driven solutions. Open finance's past and future As highlighted in a study conducted by the Cambridge Centre for Alternative Finance 1 , the terms 'open banking' and 'open finance' vary globally. Acknowledging these differences, we'll focus on the model displayed in Figure 1 due to its widespread adoption and relevance in our study. Figure 1. The three waves of innovation in financial services. The development of open finance started with open banking, which intended for banks to promote innovation by allowing customers to share their financial data with third-party service providers (TPP) and allow those TPP—fintech and techfin companies—to initiate transactions on their behalf solely in the context of payments. This proved to be an effective way to promote innovation and thus led to a broader spectrum of financial products adding loans, mortgages, savings, pensions, insurance, investments, and more. Leading to this new directive, commonly referred to as: open finance. If we take a step further—regardless of its final implementation—a third development called open data suggests sharing data beyond the traditional boundaries of the financial services industry (FSI), exponentially increasing the potential for financial services by moving into cross-sector offerings, positioning FSI as a horizontal industry rather than an independent vertical as it was previously known. Who and what plays a role in open finance? Among the different actors across open finance, the most important are: Consumers: End-users empowered to grant or revoke consent to share their data primarily through digital channels. Data holders: These are mainly financial services companies, and thereby consumer data custodians. They are responsible for controlling the data flow across the different third-party providers (TPPs). Data users: Data users are common third-party providers offering their services based on consumers’ data (upon request/consent). Connectivity providers: Trusted intermediaries that facilitate data flow, also known as TSPs in the EU and UK, and Account Aggregators in India. Regulatory authorities: Set standards, oversee processes, and may intervene in open finance implementation. They may vary according to the governance type. The interactions between all these different parties define the pillars for open finance functioning: Technology: Ensures secure data storage and the exposure-consumption of services. Standards: Establishes frameworks for data interchange schemas. Regulations and enforceability: Encompasses security policies and data access controls. Participation and trust: Enables traceability and reliability within a regulated ecosystem. Figure 2. High-level explanation of data sharing in open finance. Drivers behind open finance: Adoption, impact, and compliance Open finance seeks to stimulate innovation by promoting competition, safeguarding consumer privacy, and ensuring market stability—ultimately leading to economic growth. Additionally, it has the potential to provide financial institutions with greater access to data and better insights into consumers' preferences, allowing them to tailor their offerings and to enhance user experiences. This data sharing between the ecosystem’s participants requires a regulated set of rules to ensure data protection, security, and compliance according to each jurisdiction. As seen in Figure 3 below, there are two broad drivers of open finance adoption: regulation-led and market-driven adoption. Whether organizations adopt open finance depends on factors like market dynamics, digital readiness, and regulatory environment. Figure 3. An illustrative example of open finance ecosystem maturity. Even though there is not one single, official legal framework specifying how to comply with open finance, countries around the world have crafted their own specific set of norms as guiding principles. Recent market research reports reveal how several countries are already implementing open finance solutions, each coming from different starting points, with their own economic goals and policy objectives. In Europe, the Revised Payment Services Directive (PSD2) combined with the General Data Protection Regulation (GDPR) form the cornerstone of the regulatory framework. The European Commission published a proposal in June 2023 for a regulation on a framework for Financial Data Access 2 (FiDA) set to go live in 2027. 3 In the UK, open finance emerged from the need to address the market power held by a few dominant banks. In India, open finance emerged as a solution to promote financial inclusion by enabling identity verification for accounts opening through the national ID system. The aim is to create a single European data space – a genuine single market for data, open to data from across the world – where personal as well as non-personal data, including sensitive business data, are secure and businesses also have easy access to an almost infinite amount of high-quality industrial data, boosting growth and creating value, while minimising the human carbon and environmental footprint. 4 Build vs. buy: Choosing the right open finance strategy One of the biggest strategic decisions financial institutions face is whether to build their own open finance solutions in-house or buy from third-party open finance service providers. Both approaches come with trade-offs: Building in-house provides full ownership, flexibility, and control over security and compliance. While it requires significant investment in infrastructure, talent, and ongoing maintenance, it ensures lower total cost of ownership (TCO) in the long run, avoids vendor lock-in, and offers complete traceability—reducing reliance on external providers and eliminating “black box” risks. Institutions that build their own solutions also benefit from customization to fit specific business needs and evolving regulations. Buying from a provider accelerates time to market and reduces development costs while ensuring compliance with industry standards. However, it introduces potential challenges such as vendor lock-in, limited customization, and integration complexities with existing systems. For financial institutions that prioritize long-term cost efficiency, compliance control, and adaptability, the building approach offers a strategic advantage—though it comes with its own set of challenges. What are the challenges and why do they matter? As open finance continues to evolve, it brings significant opportunities for innovation—but also introduces key challenges that financial institutions and fintech companies must navigate. These challenges impact efficiency, security, and compliance, ultimately influencing how quickly new financial products and services can reach the market. 1. Integration of data from various sources Open finance relies on aggregating data from multiple institutions, each with different systems, APIs, and data formats. This complexity leads to operational inefficiencies, increased latency, and higher costs associated with data processing and infrastructure maintenance. Without seamless integration, financial services struggle to provide real-time insights and a frictionless user experience. 2. Diverse data types Financial data comes in various formats—structured, semi-structured, and unstructured—which creates integration challenges. Many legacy systems operate with rigid schemas that don’t adapt well to evolving data needs, making it difficult to manage new financial products, regulations, and customer demands. Without flexible data structures, innovation is slowed, and interoperability between systems becomes a persistent issue. 3. Data security With open finance, vast amounts of sensitive customer data are shared across multiple platforms, increasing the risk of breaches and cyberattacks. A single vulnerability in the ecosystem can lead to data leaks, fraud, and identity theft, eroding customer trust. Security vulnerabilities have financial consequences and can result in legal examination and long-term reputational damage. 4. Regulatory compliance Navigating a complex and evolving regulatory landscape is a major challenge for open finance players. Compliance with data protection laws, financial regulations, and industry standards—such as GDPR or PSD2—requires constant updates to systems and processes. Failure to comply can lead to legal penalties, substantial fines, and loss of credibility—making it difficult for institutions to operate confidently in a global financial ecosystem. These challenges directly impact the ability of financial institutions to innovate and launch new products quickly. Integration issues, security concerns, and regulatory complexities contribute to longer development cycles, operational inefficiencies, and increased costs—ultimately slowing the time to market for new financial services. In a highly competitive industry where speed and adaptability are critical, overcoming these challenges is essential for success in open finance. MongoDB as the open finance data store To overcome open finance’s challenges, a flexible, scalable, secure, and high-performing data store is required. MongoDB is an ideal solution, as it offers a modern, developer-friendly data platform that accelerates innovation while meeting the critical demands of financial applications. Seamless integration with RESTful JSON APIs According to OpenID’s 2022 research , most open finance ecosystems adopt RESTful JSON APIs as the standard for data exchange, ensuring interoperability across financial institutions, third-party providers, and regulatory bodies. MongoDB’s document-based model natively supports JSON, making it the perfect backend for open banking APIs. This enables financial institutions to ingest, store, and process API data efficiently while ensuring compatibility with existing and emerging industry standards. Flexible data model for seamless integration Open finance relies on diverse data types from multiple sources, each with different schemas. Traditional relational databases require rigid schema migrations, often causing downtime and disrupting high-availability services. MongoDB's document-based model—with its flexible schema—offers an easy, intuitive, and developer-friendly solution that eliminates bottlenecks, allowing financial institutions to adapt data structures dynamically, all without costly migrations or downtime. This ensures seamless integration of structured, semi-structured, and unstructured data, increasing productivity and performance while being cost-effective, enables faster iteration, reduced complexity, and continuous scalability. Enterprise-grade security and compliance Security and compliance are non-negotiable requirements in open finance, where financial data must be protected against breaches and unauthorized access. MongoDB provides built-in security controls, including encryption, role-based access controls, and auditing. It seamlessly integrates with existing security protocols and compliance standards, ensuring adherence to regulations such as GDPR and PSD2. MongoDB also enforces privileged access controls and continuous monitoring to safeguard sensitive data, as outlined in the MongoDB Trust Center . Reliability and transactional consistency Financial applications demand zero downtime and high availability, especially when processing transactions and real-time financial data. MongoDB’s replica sets ensure continuous availability, while its support for ACID transactions guarantees data integrity and consistency—critical for handling sensitive financial operations such as payments, lending, and regulatory reporting. The future of open finance The evolution of open finance is reshaping the financial industry, enabling seamless data-sharing while introducing new challenges in security, compliance, and interoperability. As financial institutions, fintechs, and regulators navigate this shift, the focus remains on balancing innovation with risk management to build a more inclusive and efficient financial ecosystem. For organizations looking to stay ahead in this landscape, choosing the right technology stack is crucial. MongoDB provides the flexibility, scalability, and security needed to power the next generation of open finance applications—helping financial institutions accelerate innovation while ensuring compliance and data integrity.

The telecommunications industry is currently undergoing a profound transformation, fueled by innovations in 5G networks, the growth of Internet of Things applications, and the rapid rise of AI. To capitalize on these technologies, companies must effectively handle increasing volumes of unstructured data, which now represents up to 90% of all information, while also developing modern applications that are flexible, high-performance, and scalable. However, the telecommunications industry's traditional reliance on relational databases such as PostgreSQL presents a challenge to modernization. Their rigid structures limit adaptability and can lead to decreased performance as table complexity grows. With this in mind, this blog post explores how telecom companies can modernize their legacy applications by leveraging MongoDB’s modern database and its document model. With MongoDB, telecom companies can take advantage of the latest industry innovations while freeing their developers from the burdens of maintaining legacy systems. Navigating legacy system challenges Legacy modernization refers to the process of updating a company’s IT infrastructure to align it with the latest technologies and workflows, and ultimately advancing and securing strategic business goals. For telecom companies, this modernization involves overcoming the limitations of their legacy systems, which hinder adjustment to changing market conditions that demand greater system scalability and availability to run real-time operations. The main drawbacks of legacy technologies like relational databases stem from their design, which wasn’t built to support the data processing capabilities required for modern telecom services. These limitations, as illustrated in Figure 1 below, include rigid data schemas, difficulty handling complex data formats, limited scaling ability, and higher operational costs for maintenance. Figure 1. The limitations of legacy systems. Expanding on these limitations, relational databases depend on a predefined schema, which becomes difficult to modify once established, as changes entail extensive restructuring efforts. In telecommunications, handling growing data volumes from connected devices and 5G networks can rapidly become burdensome and costly due to frequent CPU, storage, and RAM upgrades. Over time, technology lock-in can further escalate costs by hindering the transition to alternative solutions. Altogether, these factors hold back modernization efforts urging telecoms to transform their legacy systems to newer technologies. To overcome these challenges, telecom companies are replacing these legacy systems with modern applications that effectively provide them with greater scalability, enhanced security, and high availability, as shown in Figure 2. However, achieving this transition can be a daunting task for some organizations due to the complexity of current systems, a lack of internal technical expertise, and the hurdles of avoiding downtime. Therefore, before transforming their outdated systems, telecom companies must carefully select the appropriate technologies and formulate a modernization strategy to facilitate this transition. Figure 2. Characteristics of modern applications. Getting onboard with MongoDB Enter MongoDB. The company’s document-oriented database offers a flexible data model that processes any information format, easily adapting to specific application requirements. MongoDB Atlas —MongoDB’s unified, modern database—delivers a robust cloud environment that efficiently manages growing data volumes through its distributed architecture, ensuring seamless connectivity and enhanced performance. Moreover, as telecom providers prioritize cybersecurity and innovation, MongoDB includes robust security measures—comprising encryption, authentication, authorization, and auditing—to effectively protect sensitive information and ensure regulatory compliance. Additionally, leveraging MongoDB’s document model with built-in Atlas services like Vector Search , Atlas Charts , and Stream Processing allows telecommunications organizations to streamline advanced industry cases, including single customer view, AI integrations, and real-time analytics. Figure 3. Core MongoDB modernization features for Modernization. Recognizing these benefits, leading telecom companies like Nokia , Swisscom , and Vodafone have successfully modernized their applications with MongoDB. However, selecting the right technology is only part of the modernization process. In order to ensure a successful and effective modernization project, organizations should establish a comprehensive modernization strategy. This process typically follows one of three following paths: Data-driven modernization: this approach transfers all data from the legacy system to the new environment and then migrates applications. Application-driven modernization (all-or-nothing): this approach executes all reads and writes for new applications in the new data environment from the start, but leaves the business to decide when to retire existing legacy applications. Iterative modernization (one-step-at-a-time): this approach blends the previous paths, starting with the modernization of the least complex applications and incrementally moving forward into more complex applications. Read this customer story to learn more about telecoms migrating to MongoDB. With this overview complete, let's dive into the migration process by examining the iterative modernization of a telecom billing system. Modernizing a telecom billing system Telecom billing systems often consist of siloed application stacks segmented by product lines like mobile, cable, and streaming services. This segmentation leads to inefficiencies and overly complex architectures, highlighting the need to simplify these structures. With this in mind, imagine a telecom company that has decided to modernize its entire billing system to boost performance and reduce complexity. In the initial stage, telecom developers can assess the scope of the modernization project, scoring individual applications based on technical sustainability and organizational priorities. Applications with high scores undergo further analysis to estimate the re-platforming effort required. Later on, a cross-functional team selects the first component to migrate to MongoDB, initiating the billing system modernization. This journey then follows the steps outlined in Figure 4: Figure 4. The modernization process. First, developers analyze legacy systems by examining the codebase and the underlying architecture of the chosen billing system. Then, developers create end-to-end tests to ensure the application functions correctly when deployed. Later, developers design an architecture that incorporates managerial expectations of the desired application. Next, developers rewrite and recode the legacy application to align with the document model and develop APIs for MongoDB interaction. Following this, developers conduct user tests to identify and resolve any existing application bugs. Finally, developers migrate and deploy the modernized application in MongoDB, ensuring full functionality. Throughout this process, developers can leverage MongoDB Relational Migrator to streamline the transition. Relational Migrator helps developers with data mapping and modeling, SQL object conversion, application code generation, and data migration—corresponding to steps three, four, and five. Additionally, telecom companies can accelerate modernization initiatives by leveraging MongoDB Professional Services for dedicated, tailored end-to-end migration support. Our experts work closely with you to provide customized assistance, from targeted technical support and development resources to strategic guidance throughout the entire project. Building on this initial project, telecom companies can progressively address more complex applications, refining their approach to support a long-term modernization strategy. Next steps By revamping legacy applications with MongoDB, telecom companies can improve their operations and gain a competitive edge with advanced technology. This shift allows telcos to apply the latest innovations and free developers from the burdens of maintaining legacy systems.

ORiGAMi: A Machine Learning Architecture for the Document Model
The document model has proven to be the optimal paradigm for modern application schemas. At MongoDB, we've long understood that semi-structured data formats like JSON offer superior expressiveness compared to traditional tabular and relational representations. Their flexible schema accommodates dynamic and nested data structures, naturally representing complex relationships between data entities. However, the machine learning (ML) community has faced persistent challenges when working with semi-structured formats. Traditional ML algorithms, as implemented in popular libraries like scikit-learn and pandas , operate on the assumption of fixed-dimensional tabular data consisting of rows and columns. This fundamental mismatch forces data scientists to manually convert JSON documents into tabular form—a time-consuming process that requires significant domain expertise. Recent advances in natural language processing (NLP) demonstrate the power of Transformers in learning from unstructured data but their application to semi-structured data has been under-studied. To bridge this gap, MongoDB's ML research group has developed a novel Transformer-based architecture designed for supervised learning on semi-structured data (e.g., JSON data in a document model database). We call this new architecture ORiGAMi (Object Representation through Generative, Autoregressive Modelling), and we're excited to make it available to the community at github.com/mongodb-labs/origami . It includes components that make training a Transformer model feasible on datasets entailing as few as 200 labeled samples. By combining this data efficiency with the flexibility of Transformers, ORiGAMi enables prediction directly from semi-structured documents, without the cumbersome flattening and manual feature extraction required for tabular data representation. You can read more about our model on arXiv . Technical innovation The key insight behind ORiGAMi lies in its tokenization strategy: documents are transformed into sequences of key-value pairs and special structural tokens that encode nested types like arrays and subdocuments: These token sequences serve as input to the Transformer model trained to predict the next token given a portion of the document, similar to how large language models (LLMs) are trained on text tokens. What’s more, our modifications to the standard Transformer architecture include guardrails to ensure that the model only generates valid, well-formed documents, and a novel position encoding strategy that respects the order invariance of key/value pairs in JSON. These modifications also allow for much smaller models compared to LLMs, which can thus be trained on consumer hardware in minutes to hours depending on dataset size and complexity, versus days to weeks for LLMs. By reformulating classification as a next-token prediction task, ORiGAMi can predict any field within a document, including complex types like arrays and nested subdocuments. This unified approach eliminates the need for separate models or preprocessing pipelines for different prediction tasks. Example use case Our initial focus has been supervised learning: training models from labeled data to make predictions on unseen documents. Let's explore a practical example of user segmentation. Consider a collection where each document represents a user profile, containing both simple fields and complex nested structures: { "_id": "user_7842", "email": "sarah.chen@example.com", "signup_date": "2024-01-15", "device_history": [ { "device": "mobile_ios", "first_seen": "2024-01-15", "last_seen": "2024-02-11" }, { "device": "desktop_chrome", "first_seen": "2024-01-16", "last_seen": "2024-02-10" } ], "subscription": { "plan": "pro", "billing_cycle": "annual", "features_used": ["analytics", "api_access", "team_sharing"], "usage_metrics": { "storage_gb": 45.2, "api_calls_per_day": 1250, "active_projects": 8 } }, "user_segment": "enterprise_power_user" // <-- target field } Suppose you want to automatically classify users into segments like "enterprise_power_user", "smb_growth", or "early_stage_startup" based on their behavior and characteristics. Some documents in your collection already have correct labels, perhaps assigned through manual analysis or customer interviews. Traditional ML approaches would require flattening this rich document structure, leading to very sparse tables and potentially losing important hierarchical relationships. With ORiGAMi, you can: Train directly on the raw documents with existing labels Preserve the full context of nested structures and arrays Make predictions for the "user_segment" field on new users immediately after signup Update predictions as user behavior evolves without rebuilding feature pipelines Getting started with ORiGAMi We're excited to be open-sourcing ORiGAMi ( github.com/mongodb-labs/origami ) and you can read more about our model on arXiv . We've also included a command-line interface that lets users make predictions without writing any code. Training a model is as simple as pointing ORiGAMi to your MongoDB collection: origami train <mongo-uri> -d app -c users Once trained, you can generate predictions and seamlessly integrate them back into your MongoDB workflow. For example, to predict user segments for new signups (from the analytics.signups collection ) and write the resulting predictions back to MongoDB to an analytics.predicted collection: origami predict <mongo-uri> -d analytics -c signups --target user_segment --json | mongoimport -d analytics -c predicted For those looking to dive deeper, we've also included several Jupyter notebooks in the repository that demonstrate advanced features and customization options. Model performance can be improved by adjusting the hyperparameters. We're just scratching the surface of what's possible with document-native machine learning, and have many more use cases in mind. We invite you to explore the repository, contribute to the project, and share how you use ORiGAMi to solve real-world problems. Head over to the ORiGAMi github repo , play around with it, and tell us about new ways of applying it and problems it’s well-suited to solving.
ZEE5: A Masterclass in Migrating Microservices to MongoDB Atlas
ZEE5 is a leading Indian over-the-top (OTT) video-streaming platform that delivers streamed content via Internet-connected devices. The platform offers a wide variety of content—movies, TV shows, web series, and original programming—across multiple genres and languages. Owned by Zee Entertainment Enterprises Limited , ZEE5 produces over 260 hours of content daily, with a monthly active user base of more than 119.5 million users across 190 countries. ZEE5’s operations and customer satisfaction are dependent on its backend infrastructure being robust and scalable to handle immense traffic and complex workflows. In order to future-proof its infrastructure and to maintain its competitive edge, the company needed to streamline operations and enhance its database management capabilities. This included the migration of its entire OTT platform, including a total of 100+ microservices and 80+ databases to Google Cloud. Pramod Prakash, Senior Vice President of Engineering at ZEE5, was on the stage of MongoDB.local Bangalore in 2024 . He shared insights into how ZEE5 managed this migration without hindering performance or disrupting its services. “It was a massive project which required a very carefully orchestrated migration plan,” said Prakash. Massive migration, zero downtime: Challenge accepted ZEE5’s team embarked on an ambitious journey to migrate a total of 40+ microservices (out of its 100+ microservices) to MongoDB Atlas . These were previously running on the Community Edition of MongoDB and on other NoSQL databases. One of the challenges of this migration was to ensure continuous data flow for the platform’s 119.5 million streaming users. To do so, Prakash and his team created multiple environments using a change data capture tool . This ensured continuous replication of data so the user experience would not be impacted. “We had to build four environments: dev, QA [Quality Assurance], UAT [User Acceptance Testing], and production,” explained Prakash. “We needed to keep testing and verifying each environment, and then finally enter the production phase when we migrated the data and moved the traffic.” The approach involved migrating production data twice: first for testing and then for the final cutover. This was to minimize any data loss. ZEE5 used MongoDB Atlas’ integrated tools mongosync and mongomirror . The tools helped achieve an essential goal: avoiding any downtime. “We migrated this entire mammoth application with zero downtime!” said Prakash. “We have not stopped ZEE5’s operations at all.” “The second important thing is the performance: you want to be 100% sure that the entire scale and peak traffic will work seamlessly within the new cloud environment,” added Prakash. ZEE5 relied on MongoDB Professional Services (PS)’s support. The PS team helped architect and plan the entire migration strategy. They also accompanied Prakash’s team step by step to ensure there would be no unexpected disruptions. The production environment was built and tested rigorously before the final migration to ensure seamless performance at peak traffic levels. “We iterated until we were 100% sure that the new environment was ready to take up ZEE5’s peak traffic. Functionally, it was all perfect,” said Prakash. The power of the Atlas platform According to Prakash, the power of MongoDB Atlas lies in the fact that it offers a fully managed platform. “There is no maintenance overhead at all,” he said. “All upgrades happen automatically without any downtime. We are also leveraging auto-scaling capabilities and point-in-time recovery.” All of this enables efficient handling of varying traffic loads without manual intervention. Additionally, data recovery capabilities are enhanced, and most importantly, the engineering team can prioritise application development rather than operational maintenance. As of February 2025, MongoDB Atlas supports a total of seven key use cases at ZEE5: payments, subscriptions, plans and coupons, video engineering, Zee Music (users’ preferences and playlists), content metadata, and the platform’s communication engine (SMS and email notifications). Looking ahead, ZEE5 is working on more use cases powered by MongoDB. For example, the company is looking to completely migrate their master data source for content metadata to MongoDB Atlas. ZEE5 is also considering relying on MongoDB Atlas to support and enhance its search and recommendations capabilities. Interested in learning how MongoDB is powering other companies applications?

Debunking MongoDB Myths: Security, Scale, and Performance
MongoDB has come a long way since its founding in 2007. Many people first encountered MongoDB during its early years. They formed opinions about the database based on impressions from 2012 to 2014. However, much has changed since then. Over the past eleven years, MongoDB has made significant strides. Foremost being the launch of MongoDB Atlas in 2016. It has placed a substantial focus on improving the four critical areas that matter most to businesses and developers alike: security, durability, availability, and performance. Security: Protecting sensitive data from unauthorized access and ensuring regulatory compliance. Durability: Ensuring data remains intact and reliable, even during system failures or unexpected disruptions. Availability: Minimizing downtime and maintaining system operation, no matter what happens. Performance: Delivering fast, consistent application response times and scaling efficiently to meet growing demand. These advancements have earned the trust of some of the world’s largest enterprises, including Toyota , Cisco , Wells Fargo , Bosch , and Verizon . Yet despite this progress, outdated myths regarding MongoDB persist—particularly in these four foundational areas. In this blog, we will tackle those misconceptions head on and set the record straight about MongoDB’s security, durability, availability, and performance. Let’s dive in. Myth 1: “MongoDB is not as secure as a relational database” One of the most persistent myths about MongoDB is that it is not secure—certainly not as secure as traditional relational databases. This misconception likely stems from a series of ransomware attacks in the mid-2010s. Hackers exploited unsecured databases that lacked proper authentication and were left exposed on default TCP ports. While these incidents highlighted poor configuration practices, they have unfairly cast a shadow over MongoDB’s contemporary security capabilities. MongoDB provides robust, intelligent security features designed to protect sensitive data at every stage of its lifecycle. MongoDB encrypts data both in transit and at rest , just like other leading NoSQL and relational databases. However, what sets MongoDB apart is its ability to keep data encrypted while in use. With Queryable Encryption , an industry-first innovation unique to MongoDB, sensitive data can remain encrypted even while it is queried. This eliminates the need to decrypt the data and reduces exposure to threats. MongoDB also supports flexible authentication and authorization that seamlessly integrates with many identity management systems. Features like role-based access control and fine-grained permissions ensure users only have access to what they are authorized for. Concurrently, intuitive configuration makes these controls easy to implement. Beyond encryption and access control, MongoDB includes powerful auditing tools to monitor database activity and advanced network security features, such as IP allow-listing and private networking . Together, these capabilities provide comprehensive protection against unauthorized access and help organizations meet strict compliance requirements. Best of all, these advanced security features are included by default in both MongoDB Atlas and MongoDB Enterprise Advanced at zero cost. MongoDB’s approach simplifies security management while minimizing expenditure. This allows teams to focus on building applications with confidence that their data is protected. Myth 2: “MongoDB’s multi-cloud capabilities do not set it apart from other databases” At first glance, the claim that MongoDB is multi-cloud may not sound special. After all, plenty of databases are available through more than one cloud provider - however, this should not be confused with them all being multi-cloud . True multi-cloud supports ‘cross-cloud’ deployments, i.e. the ability to deploy individual nodes of a single cluster across multiple cloud providers. This distinction is often obfuscated by those vendors unable to run their clusters in such a configuration. Support for multi-cloud clusters in Atlas became generally available in October of 2020. MongoDB Atlas enables deployment not only on Amazon Web Services (AWS), Microsoft Azure, or Google Cloud but also across all three clouds simultaneously with a single cluster. It is possible to set up and configure cross-cloud deployments solely from the Atlas management console. No further configuration is required via the individual cloud providers. This is more than just a convenience; it is a transformative capability that eliminates the boundaries between cloud providers. With MongoDB Atlas, it is as if AWS, Azure, and Google Cloud operate as one unified cloud environment. Why does this matter? For starters, deploying a single database cluster across multiple clouds removes the operational complexity of managing data replication and migration between providers. Seamless data mobility can be achieved. The hardest part of any application to move—the data—now becomes the easiest. Multicloud also enables the creation of application architectures that exploit the best services from multiple cloud providers simultaneously. In addition, cross-cloud deployments deliver unmatched resiliency. With cross-cloud failover, in the event of an outage, data can be automatically switched to another cloud provider in the same geographic region. Thus ensuring uninterrupted service. Finally, MongoDB Atlas provides the flexibility to meet regional and cloud provider preferences with ease. Atlas spans 115+ supported regions across all three major cloud providers . This makes it easy to meet customer demands or comply with local regulations using a single database. MongoDB Atlas gives us the ability to run our database on multiple clouds through the same service. With Atlas, we have the freedom from lock-in—each client can choose where they are the most comfortable hosting their data. Gary Hoberman, CEO and Founder - Unquork Myth 3: “I get that MongoDB is built for horizontal scaling, but it is so painful to scale” Horizontal scaling, also known as scale-out, is a core strength of MongoDB. It allows workloads to be distributed by adding more nodes as data and applications expand. However, some beliefs have perpetuated that scaling MongoDB is difficult and complex. The reality? MongoDB makes scaling not just possible, but seamless—whether scaling out horizontally or scaling up vertically. With MongoDB Atlas, vertical scaling—or scale-up—is simple. By enabling auto-scaling , MongoDB Atlas dynamically adjusts cluster resources to meet workload demands. Adding more RAM, CPU, or storage capacity can be performed automatically and on-demand. This ensures optimal performance without continual manual intervention or oversight. If you need to move beyond vertical scaling, MongoDB offers three flexible ways to scale horizontally : Hashed sharding : Data is distributed randomly across nodes using a hashed shard key. This ensures an even distribution of data and workloads to prevent bottlenecks. Ranged sharding : Data is distributed based on ranges of a specific field. This enables fine-grained control over how data is divided. This approach is especially useful for preventing hotspots in workloads. Zone sharding : Data is distributed geographically. This enables compliance with data residency requirements and reduces latency by keeping data closer to users. What happens if the initial sharding strategy does not go as planned? MongoDB addresses this challenge with the ability to refine shard keys and reshard a collection with zero downtime. This ensures data distribution strategies can adapt as needs evolve, all without disrupting applications or users. Myth 4: “Since MongoDB is built for flexibility, it must not be very performant” One common misconception about MongoDB is that its flexibility and versatility must come at the expense of performance. After all, can such an agile database—one built for developers to model data however they want—really deliver the speed and efficiency of a performance-first solution? MongoDB is designed to provide both; unmatched flexibility and exceptional performance —all while keeping costs low. MongoDB’s performance stems from its intelligent architecture and powerful features. Ad hoc queries, indexing , and real-time aggregations make it easy to access and analyze data quickly. How fast are queries? Primary key or indexed queries typically execute in milliseconds. Even complex queries that are not indexed remain efficient. Performance typically is dependent on factors like collection size and machine specifications. What about workloads like search and analytics? Some developers might assume these would compete for resources and degrade performance on operational tasks. However, MongoDB solves this with workload isolation . This feature ensures that operational and nonoperational workloads are separated. This enables each to run at peak performance without requiring costly and time-consuming extract, transform, and load (ETL) processes. Network latency? For globally distributed applications, MongoDB’s hedged reads enable the nearest replica nodes to be read from rather than waiting for a response from distant nodes. This reduces latency and ensures applications remain highly responsive. MongoDB’s real-world performance is backed by incredible use cases: Amadeus processes 630 million bookings per year. Idealo supports 200,000 queries and 60,000 updates per second. Temenos achieves 150,080 transactions per second. This was before the release of MongoDB 8.0 , the most performant version of the database yet. MongoDB 8.0 has delivered: 36% faster reads 32% faster reads and updates 56% faster bulk inserts A stunning 200% improvement for time series queries MongoDB Atlas doesn’t just solve our performance issues. It makes life easier for web developers, who can build and maintain simpler, more straightforward code. Moutia Khatiri, CTO - Tech Accelerator, L’Oreal MongoDB Today MongoDB has evolved far beyond the myths perpetuated during its early years. MongoDB 8.0 delivers robust capabilities across security, durability, availability, and performance. It encrypts sensitive data throughout its lifecycle and enables seamless cross-cloud deployments. It simplifies horizontal and vertical scaling and powers some of the world’s most demanding applications. These capabilities solidify MongoDB’s position as the database of choice for modern applications.

Advancing Encryption in MongoDB Atlas
Maintaining a strong security posture and ensuring compliance with regulations and industry standards are core responsibilities of enterprise security teams. However, satisfying these responsibilities is becoming increasingly complex, time-consuming, and high-stakes. The rapid evolution of the threat landscape is a key driver of this challenge. In 2024, the percentage of organizations that experienced a data breach costing $1 million or more jumped from 27% to 36%. 1 This was partly fueled by a 180% surge from 2023 to 2024 in vulnerability exploitation by attackers. 2 Concurrently, regulations are tightening. Laws like the Health Insurance Portability and Accountability Act (HIPAA) 3 and the U.S. Securities and Exchange Commission’s cybersecurity regulations 4 have introduced stricter security requirements. This has raised the bar for compliance. Thousands of enterprises rely on MongoDB Atlas to protect their sensitive data and support compliance efforts. Encryption plays a crucial role on three levels; securing data at rest, in transit, and in use. However, security teams need more than solely strong encryption. Flexibility and control are essential to align with an organization’s specific requirements. MongoDB is introducing significant upgrades to MongoDB Atlas encryption to meet these needs. This includes enhanced customer-managed key (CMK) functionality and support for TLS 1.3. This post explores these improvements, along with the planned deprecation of outdated TLS versions, to strengthen organizations’ security postures. Why customer-managed keys (CMKs) matter Customer-managed keys (CMKs) are a security and data governance feature that delivers enterprises full control over the encryption keys protecting their data. With CMKs, customers can define and manage their encryption strategy. This ensures they have ultimate authority over access to their sensitive information. MongoDB Atlas customer key management provides file-level encryption, similar to transparent data encryption (TDE) in other databases. This customer-managed encryption-at-rest feature works alongside always-on volume-level encryption 5 in MongoDB Atlas. CMKs ensure all database files and backups are encrypted. MongoDB Atlas also integrates with AWS Key Management Service (AWS KMS), Azure Key Vault , and Google Cloud KMS . This ensures customers have the flexibility to manage keys as part of their broader enterprise security strategy. Customers using CMKs retain complete control of their encryption keys. If an organization needs to revoke access to data due to a security concern or any other reason, it can do so immediately by freezing or destroying the encryption keys. This capability acts as a “kill switch,” ensuring sensitive information becomes inaccessible when protection is critical. Similarly, an organization can destroy the keys to render the data and backups permanently unreadable and irretrievable. This may be applicable should they choose to retire a cluster permanently. Announcing CMK over private networking As part of a commitment to deliver secure and flexible solutions for enterprise customers, MongoDB is introducing CMKs over private networking. This enhancement enables organizations to manage their encryption keys without exposing their key management service (KMS) to the public internet. Using CMKs in MongoDB Atlas previously required Azure Key Vault and AWS KMS to be accessible via public IP addresses prior to today. While functional, this posed challenges for customers who need to keep KMS traffic private. It forced those customers to either expose their KMS endpoints or manage IP allow lists. By using private networking, customers can now: Eliminate the need for public IP exposure. Simplify network management by removing the need to manage allowed IP addresses. This reduces administrative effort and misconfiguration risk. Align with organizational requirements that mandate the use of private networking. Customer key management over private networking is now available for Azure Key Vault and AWS KMS . Customers can enable and manage this feature for all their MongoDB Atlas projects through the MongoDB Atlas UI or the MongoDB Atlas Administration API . More enhancements are coming for MongoDB customer key management in 2025. These include secretless authentication mechanisms and CMKs for search nodes. MongoDB Atlas TLS enhancements advance encryption in transit Securing data in transit is equally vital as a foundation of encryption at rest with CMKs. To address this, MongoDB Atlas enforces TLS by default. This ensures encrypted communication across all aspects of the platform, including client connections. Now MongoDB is reinforcing its TLS implementation with key enhancements for enterprise-grade security. MongoDB is in the process of rolling out fleetwide support for TLS 1.3 in MongoDB Atlas. The latest version of the cryptographic protocol offers several advantages over its predecessors. This includes stronger security defaults, faster handshakes, and reduced latency. Concurrently, TLS versions 1.0 and 1.1 are being deprecated. The rationale for this is known weaknesses and their inability to meet modern security standards. MongoDB is aligning with industry best practices by standardizing on TLS 1.2 and 1.3. This ensures a secure communication environment for all MongoDB Atlas users. Additionally, MongoDB now offers custom cipher suite selection, giving enterprises more control over their cryptographic configurations. This feature lets organizations choose the cipher suites for their TLS connections, ensuring compliance with their security requirements. Achieving encryption everywhere This post covers how MongoDB secures data at rest with CMKs and in transit with TLS. However, what about data in use while it’s being processed in a MongoDB Atlas instance? That’s where Queryable Encryption comes in. This groundbreaking feature enables customers to run expressive queries on encrypted data without ever exposing the plaintext or keys outside the client application.
