Managed Server 10: OpenSSH Security Configuration, scheduled 9 hours ago

For several years, we have followed the OpenSSH recommendations published by Mozilla to ensure a secure and reliable SSH environment. As Mozilla has discontinued updates to these guidelines, we have decided to align our configuration with the latest recommendations from OpenSSH and Debian. This change brings our setup in line with current best practices and ensures continued security and compatibility. The update affects the Ciphers, MACs, and KexAlgorithms used in our OpenSSH server configuration.

We do not expect any issues for our customers. However, if you experience any unexpected behavior, please let us know. We are happy to adjust the configuration for individual servers as needed.
