Roelof T.

Roelof T. operates at the sharp end of cybersecurity and Open-Source Intelligence (OSINT), with a career that spans from early offensive security work to building widely adopted investigative tooling. He co-founded SensePost, helping shape modern penetration testing practices, and later founded Paterva, where he built Maltego into a standard for entity-centric analysis and link exploration. He is now focused on Ubikron—a structured OSINT platform designed to capture, enrich, and retain investigative context directly from the web, with an emphasis on control, privacy, and long-term knowledge preservation. His work sits at the intersection of engineering, analysis, and tradecraft: building systems that analysts actually use, while continuously exploring how intelligence workflows evolve in response to AI, influence operations, and large-scale data environments. He has delivered talks and training globally, but more importantly, his work reflects a consistent pattern—taking complex, messy information environments and imposing structure on them in a way that makes investigation faster, repeatable, and defensible.
