Is this basically https://www.ssllabs.com/ssltest/ but for SSH? If so, that is great. In the past, it has been great to point my sysadmin team at that site and say "My goal is get to an A+ on SSLLabs, the site will tell us what settings to tweak to get there" or to tell external stakeholders "SSLLabs gives us an A+, now stop telling me that LetsEncrypt is somehow not good enough". I'd love to have a simple tool I can point at my internal SSH servers and get a single letter grade like that.
