To help on this front we have participated in a community effort to bring the popular open source module ModSecurity to the IIS platform.

One year ago this week we challenged the security community to take an unconventional focus on defensive innovation. We called that challenge the BlueHat Prize, and tomorrow night, we will award the grand prize of $200,000 to one of the finalists, either Jared DeMott, Ivan Fratric, or Vasilis Pappas. All three finalists submitted prototype mitigations that help prevent exploits that use Return Oriented Programming (ROP) techniques.
