Built by a practitioner.
Perdition Security is led by David Sampson, a security professional with a decade of hands-on offensive and defensive experience across finance, SaaS, healthcare, and AI.
David Sampson has spent ten years in the trenches of cybersecurity — pentesting production systems, leading red team operations, building security programs from zero, and shipping the kind of secure-by-design infrastructure he's been hired to break.
He holds the CISSP and CISM certifications, and his current focus sits at the intersection of offensive security and AI: red-teaming LLM and agent systems, and building the secure AI features that other consultancies still treat as a research topic.
Perdition Security exists because most clients don't need a ten-person consulting pyramid. They need one senior practitioner who can scope honestly, execute carefully, and write a report that their engineers will actually act on. That's the entire model.
How we think.
Manual over scanner
Tools find what tools find. Real findings come from a human reading the code, the traffic, and the assumptions.
Exploitable, not theoretical
We don't pad reports with informational noise. If we report it, we exploited it — or we'll show you exactly how.
Builders and breakers
We ship production AI systems and break them for a living. That dual perspective is what makes our reviews land.
Senior accountability
The person scoping your engagement is the person doing the work and writing the report. No handoffs.
