I found this new web application vulnerability scanner today called Grendel-Scan. At first glance, it looks similar to Paros and other MITM proxy types but I assure you it is more than that.

Description:

Grendel-Scan is an open-source web application security testing tool. It has automated testing module for detecting common web application vulnerabilities, and features geared at aiding manual penetration tests.

Here we have the module screen, which shows some of Grendel’s features which are at least on par with w3af.

I will be using this for a little while, and I will post my findings. Until then, you can find more information at their website. They also have a forum and blog if you find yourself in need of assistance.
