Cool,.but from the post it seems like all it does is:

• Recommend disabling old algorithms, which you would have already done if you followed a modern hardening guide like https://infosec.mozilla.org/guidelines/openssh
• Detect if you are running a known-vulnerable version of OpenSSH, which wouldn't be an issue if you keep good patch hygiene and install your SSH server through you operating systems' package manager

So what's the point? Who is this for?

Thanks for pushing the awareness.

Personally I made sure SSH is only accessible when connected through a VPN setup for that purpose. As in, that same machine hosts a Wireguard setup (through Tailscale) and you need to connect to that first before SSH is available. And then SSH also only accepts key-based authentication. I don't think I need more than that?
