You are looking for IDP/IDS functionality. As I said, UTM boxes offer that
service usually, Fortigate boxes can do it as well. Subscription for
IDP/IDS service will often cost some extra money.

If a web server is all you want to protect, then a simple NAT router
will do all you need if you properly secure the server and web services.

What OS/Web service are you running?

How does NATting ensure protocol integrity and stop inline attacks?
Answer: It can't. You need some application layer proxy to do that.

Cheers,

It doesn't as you've so nicely put it, but, if your server is properly
secured, since I don't know what OS/Service, there is a good chancec
that you're not going to get much more protection that would do you much
good.
