Due to your organization's security policies, you may not want to reveal that you are using Cerberus or the version number when a user logs in. In Cerberus you can use the "Mask Server Identification (SSH and HTTP/S)" setting. If this option is checked, the server will use a generic identification string for the welcome message during SSH connections. The server will also omit the server header for HTTP/S connections.
In the Cerberus admin UI, navigate to Configure > Protocols >SSH SFTP Settings and check "Mask Server Identification (SSH and HTTP/S)" and "Update"
