Our vulnerability reports show that our Macs are running OpenSSH 7.9 and need to be updated to 8.1. The OS is Mojave. This doesn't seem to be as straight forward as on A PC. Any ideas on how this is done?
First thing to note is that ssh is not enabled by default on any install of OS X (excluding server, which is a now-dead version, as a separate build and customizations of OS X).
Upgrading is easy, use MacPorts (many will without question suggest homebrew, I prefer and recommend MacPorts based on historical - personal - experience).

One would have to modify
/System/Library/LaunchDaemons/ssh.plist
to use said upgraded ssh (which will get installed via MacPorts - by default - to /opt/local ), which is no small task especially for Mojave, in which /System is protected by SIP.No-one with a meaningful knowledge of security and macOS (Mac OS X) will recommend disabling SIP. One might be able to do so temporarily, but that's another hill to climb/problem to solve.

Technically, you could leave the default installed openssh alone, but that will still get used when using the macOS GUI (System Preferences > Sharing) to enable ssh ('Remote Login'), unless you managed to edit the above-named plist to point to your updated version.
