Nimer Kees is a security researcher working where offensive security meets AI, researching how systems are meant to reason and how easily they can be talked out of it. He has over a decade in the field. He started in red teaming, breaking into networks, applications, and the assumptions holding them together, before moving into security research, insider threat, and AI research. He has built research capabilities from scratch at startups and large enterprises, hiring teams, building tooling, and turning scattered findings into a research practice that ships results. Much of that work has focused on insider threat and advanced attackers, understanding how trusted access is abused and what it looks like before it happens. At Above Security, he leads AI and research, applying an attacker's instincts to insider threat detection. The goal is technology built not on how people and systems should behave, but on how they actually behave when someone tests the edges.
