John Mathot

Junior Penetration Tester | OSCP, CRTO, BSCP

John holds a B.S. in Biology from the University of Alaska Anchorage and began studying information security in 2022. Before joining KP, he took part in bug bounty programs and performed vulnerability research, finding and reporting security weaknesses in live applications and systems. That background gives him an attacker’s view of how vulnerabilities are discovered, which he now brings to his work with KP’s clients.
