Founded by a Marine Corps veteran and career penetration tester with over 15 years of experience across cybersecurity, intelligence, and special operations.
Most security programs are built around network defense. Firewalls, EDR, SIEM, vulnerability scanners. These tools matter. But they do not protect you from the attacker who walks through your front door with a cloned badge, calls your help desk with a convincing pretext, or manipulates your AI chatbot into leaking customer data.
Black Ledger Security exists to test the threats that live outside your technical perimeter. We specialize in the human attack surface: physical intrusion, social engineering, OSINT, and AI-enabled threats. These are the attack vectors that real adversaries use to bypass every technical control you own.
Black Ledger Security was founded by a career offensive security professional who spent over a decade in the United States Marine Corps before transitioning to the private sector. Military assignments included Marine Corps Forces Special Operations Command (MARSOC), where he served on a Marine Special Operations Team in direct support of special operations and intelligence agency missions across multiple theaters and joint task forces, with deployments to the CENTCOM and INDOPACOM areas of responsibility.
Since transitioning to private sector cybersecurity in 2021, he has led social engineering teams, conducted solo physical penetration tests against secured corporate and government facilities, and delivered hundreds of offensive security assessments for clients across financial services, healthcare, manufacturing, defense, and critical infrastructure. His current focus is on how large language models, deepfake technology, and agentic AI systems are reshaping the offensive security landscape.
He is the author of Dark Dossier, a weekly threat intelligence publication covering AI security, social engineering tradecraft, and emerging attack techniques.
We are not a generalist IT security firm. We do not sell antivirus, manage your firewall, or monitor your SIEM. We are offensive specialists. Every engagement is designed to answer one question: what would happen if a motivated adversary targeted your people, your facilities, or your AI systems?
Our background in special operations and intelligence gives us a perspective that most security consultants do not have. We think like adversaries because we trained as operators. We plan methodically, execute precisely, and report honestly.
