About J and D Security LLC
Over Two Decades of Security Expertise
Founder & Principle Consultant, J&D Security LLC
Jayson Miller is the founder of J&D Security LLC and a credentialed technical surveillance countermeasures professional with over two decades of experience spanning military, federal intelligence, and homeland security service.
His career began in law enforcement and criminal investigation with the United States Army, where he later transitioned into Counterintelligence before being formally trained and certified in TSCM. He has conducted technical surveillance surveys and security operations at the highest levels of the federal government, serving the Department of Defense, the National Geospatial-Intelligence Agency and the Department of Homeland Security.
Today, Jayson brings that same federal-grade methodology to corporate clients, legal professionals, and private individuals through J&D Security LLC — providing professional security assessments, TSCM surveys, and consultation services to clients who demand discretion, precision, and results.
Why Choose J&D Security
The TSCM and security consulting market includes firms of every size and quality — from large agencies with institutional credibility but limited personal attention, to individuals with consumer equipment and no verifiable professional background.
J&D Security LLC occupies a distinct position: the professional expertise of a senior government TSCM career, delivered with the personal attention and discretion of a boutique firm. Every engagement is handled by Jayson Miller directly — not assigned to a junior analyst or a technician following a checklist.
-
You speak directly with the professional conducting your engagement — not a sales representative or coordinator.
-
Your assessment is reviewed by someone who has spent 35 years doing this work at the government level — not by software or a junior reviewer.
-
Your findings are delivered in a comprehensive written report with specific, actionable recommendations — not a vague summary.
Your engagement is held in complete confidence — discretion is not a feature of our service, it is the foundation of it.
