Jamieson didn't learn cybersecurity in a classroom. He learned it by breaching systems and bypassing controls under real pressure. That background - rooted in survival, not simulation - formed a deep, practical understanding of how attackers compromise infrastructure, manipulate data, and exploit trust at scale.

Today, he works with some of the worlds largest companies to simulate advanced threats, expose blind spots, and pressure-test systems before attackers do. He's trusted in environments where security isn't optional and risk has real-world consequences.

Jamieson is routinely engaged to help solve complex, high-stakes security problems that fall outside conventional playbooks. Sometimes that involves offensive security capabilities; other times, it requires strategic coordination across legal, regulatory, and technical domains.

His value lies in identifying leverage in asymmetric environments where creativity, persistence, and technical fluency converge to produce outcomes under pressure.
