So, you will buy "specialized" security tools like firewall or
Anti-Virus, but not web content filtering tool?

I would like to see how your real-time signatures get updated with the
randomization implemented in the new VML metasploit module. Your
"countless" exploit variants will become really innumerable.

The problem is that the signatures are written for the exploit, and
not for the vulnerability.
