Co-founder and Chief Hacking Officer at River Security, where we help organizations reduce risk through offensive security, attack surface management, and incident response.

Principal Instructor at SANS, teaching SEC504: Hacker Tools, Techniques, and Incident Handling.

I started in 2009 at a Norwegian ISP in development and IT operations, led penetration testing and incident response at Netsecurity, and founded River Security in 2020. That path from builder to operator to leader shapes how I hack and how I teach. Based in Bergen, Norway.
