You can run different hosts on one web server, like company.com goes to localhost:5555 (your app or whatever) and ssh.company.com goes to localhost:8443 (let's say you're running ssh3 on that port)
* depending on your web server/reverse proxy configuration
[for instance, I run Kestrel and it really isn't designed to target more than one site; I do it, but it's like bending that Lego brick to make it fit where it shouldn't go]
