David Klein

Customer Advisory Board

I’m very excited to join Cymulate as a board advisor. Every CISO should be looking to constantly validate their investments in security and to test their defenses. I believe Cymulate should be in every CISO’s arsenal, and I’m thrilled to become a part of their journey.

Andrew Smeaton

Attackers take advantage of the lack of security control and agility of corporations. Cymulate is a great CISO ally to overcome these obstacles.

Gorka Díaz de Obre

Continuous security validation (CSV) is a top priority to ensure our security posture is continuously optimized. The output suits technical and executives and facilitates data driven risk conversations. I see Cymulate as a security partner opposed to a security technology, using Cymulate allows us to keep our security vendors honest.

Dan Baylis
Head of Information Security Operations

With Cymulate I can identify unintended consequences of ongoing business-as-usual IT changes and their end-to-end testing coverage provides me the confidence that key controls are functioning optimally all the time.
