CORE IMPACT v5.1 includes enhancements to address the significant increase in client-side attacks on end-user applications as well as enhancement to existing functionality. This version makes it even easier for network and security administrators to safely and efficiently exploit vulnerabilities in their network, replicating the kinds of access a hacker, worm or virus could achieve, and proving actual paths of attacks that must be eliminated.

If you haven't seen their Flash Demo of a real pen test in action using Core Impact, I highly recommend it. It will blow your mind.
