Gotchas - check before you buy

Unpatched servers linger: 14M stayed exposed to regreSSHion because admins don't update

Misconfiguration creates exploit paths; hardening is entirely on you

medium

Free, but enterprise support costs extra — now sells an OpenSSH support service

low

No official security page — returned 404 in our check
