Network Security
MongoDB Realm uses TLS 1.3 to secure all network requests to and from your application, including apps that connect from a Realm SDK as well as queries and operations on a linked MongoDB Atlas data source. The TLS certificate is pre-defined and cannot be customized.

MongoDB Realm only sends requests from the following IP addresses. You can copy this list to an allowlist on your firewall:

IP Access List
MongoDB Realm allows client requests from the enabled entries in the app's IP access list. Allowed requests will still use Realm's authentication and authorization rules. By default, your Realm app allows access from any client.
