Surveillance — both physical and technical — represents one of the most insidious threats facing governments, law enforcement operations, and corporate entities. Adversaries conduct surveillance to gather intelligence, map organizational structures, and identify vulnerabilities prior to an operation or attack. OJN's counter-surveillance teams are drawn from former government surveillance detection units and bring operational experience across physical surveillance detection routes, technical surveillance countermeasures (TSCM), and digital surveillance identification. We provide clients with early warning of hostile surveillance activity, detailed threat actor profiling, and practical mitigation recommendations. Our approach is systematic, discreet, and grounded in professional intelligence tradecraft.
