Our Origin Story in a Nutshell

KeyCaliber was founded by a former Executive Office of the President and Department of Homeland Security security leader who observed that the cybersecurity community was usually missing half of the risk equation (the Impact side) because there were so many challenges around getting the data from folks outside of the cybersecurity department.

KeyCaliber’s mission is to bring this missing piece to security and IT teams so that they can optimize their precious resources and ensure cyber resilience.

We have years of experience on the defensive and offensive side of cyber so we fully understand how difficult it is to secure and operate complex environments in the face of cyber attacks of increasing sophistication and frequency. We are here to make the fight not just manageable but winnable.
