Board of Directors

Advising our CEO and senior management team in the overall business approach is Paragon’s Board of Directors. Comprised of experienced individuals from the Department of Defense, Federal Cybersecurity, Military and Legislative communities. The Board of Directors also serves as our Proxy Board, which creates an independent operating unit and separate Paragon from its foreign parent shareholder and allows us to leverage for the benefit of our US Government clients the economies of scale of a $9 Billion global corporation, while at the same time precluding the parent organization from any substantive knowledge of Paragon’s work in the cleared or US government environments.
