Does anyone use Mod Security?

Good or Bad?

Thanks.

I hadn't heard of it before, did anyone end up using it?

Sounds great:

Greetings:

We've been using mod_security from http://www.modsecurity.org/ since version 1.5ish (latest release is 1.86).

It is a rock solid product, which when used properly, can greatly enhance security for Apache, PHP, and CGI.

Thank you.

It not only enhances security, but boosts Apache performance during high loads. If you tune it right, and manage the server.
