Chief Security Architect
Mohamad Foustok
Mohamad has led the development of secure software and mission-critical security systems for more than 25 years. He designed the first in-browser crypto module to receive FIPS 140-2 certification and the only FIPS 140-3 compliant solution for securing commercial devices in classified spaces.
His career includes direct collaborations with the NSA, CIA, DISA, and DoD to deliver highly secure communication systems, including one of the only software platforms in the world validated to thwart both Spectre and Meltdown attacks per NSA review.
He earned a Bachelor of Engineering degree from Imperial College London and holds a Master's degree along with PhD studies in Computer Science (ABD), maintaining a 4.0 GPA.
