MongoDB and TLS 1.3

MongoDB supports TLS 1.3 on Windows, particularly in newer versions (6.0.7+, 7.0+) which utilize OpenSSL 3.0, and via MongoDB Atlas.

While TLS 1.3 offers superior security and performance, it requires Windows 11 or Windows Server 2022 for native OS-level support. 

  • MongoDB Version Support: TLS 1.3 is supported, with 6.0.7 and 7.0+ featuring OpenSSL 3.0, which enhances security.
  • Operating System Requirements: Native and fully supported TLS 1.3 in Windows is available in Windows 11 and Windows Server 2022.
  • Driver Support: MongoDB drivers (e.g., .NET) are moving towards TLS 1.3, with some requiring manual configuration to enable it.
  • Atlas Support: MongoDB Atlas is rolling out TLS 1.3 by default, for enhanced security and lower latency.
  • Configuration: On self-managed Windows servers, you may need to ensure the operating system has TLS 1.3 enabled, as older Windows versions do not support it officially. 

For the most secure, up-to-date connection, ensuring both MongoDB and the Windows host are on recent versions is recommended.
