Counter-intelligence
Espionage and illegal surveillance don’t always look like a “hack”. More often, it’s quiet and practical: a covert microphone in a meeting room, a tracker on a vehicle, a burst transmitter that only activates for seconds, or communications intercepted through signalling-layer abuse or rogue infrastructure.
NSI Global’s Counterintelligence services are designed to detect, prevent and neutralise covert threats across physical environments and communications systems — helping government, corporates, and high-risk individuals protect sensitive conversations, strategy, and operational security.
What is Counterintelligence?
Counterintelligence is the discipline of identifying and stopping hostile intelligence collection before it compromises decisions, negotiations, safety or national interests. In practice, that means confirming whether your environments, vehicles, communication pathways and working habits are being exploited, and putting controls in place to prevent it.
At NSI Global, Counterintelligence solutions are delivered through Technical Surveillance Counter Measures (TSCM) and related counter-surveillance services. We locate and neutralise threats such as hidden cameras and microphones, cellular/5G bugs, covert Wi-Fi/Bluetooth devices, GPS trackers, keystroke loggers and phone or line taps. We also identify the technical security gaps that make eavesdropping easier, from insecure meeting setups to vulnerable telephony and rogue IoT.
The result is not guesswork. It’s evidence-based assurance: either your space is clear, or you have a defensible path to action if something is found.
Who Should Consider Counterintelligence?
Government Agencies, Ministers & Senior Officials
Government environments are prime targets for economic and state-sponsored espionage, especially around classified briefings, procurement, inter-agency planning and high-profile engagements. Counterintelligence services help protect committee rooms, temporary venues, official residences, and ministerial or pooled vehicles — with options for both scheduled inspections and real-time monitoring during sensitive meetings.
Corporations, Boards & Deal Teams
In business, one leak can shift pricing, derail an acquisition, compromise a tender, or expose product roadmaps and client data. Counterintelligence is relevant for organisations exposed to competitive intelligence gathering, insider risk, disputes or litigation, or high-value IP — particularly where sensitive discussions occur across boardrooms, collaboration spaces, offsite venues and “mobile offices”.
Executive Leadership, Public Figures & At-Risk Individuals
For senior leaders and high-profile individuals, risk follows you home and on the road. Residences, home offices, hotels, and vehicles are common surveillance targets because they sit outside normal corporate controls. Counterintelligence restores privacy and safety where it matters most — without unnecessary disruption.
Counterintelligence Sub-Services
Bug Sweeps
A disciplined, forensic approach to identifying covert surveillance devices and technical weaknesses in physical environments. This includes comprehensive on-site sweeps of offices, vehicles, residences, meeting rooms, and sensitive facilities.
Corporate Bug Sweeps
For organisations where confidentiality is a commercial advantage. These engagements verify that decision-making spaces and supporting systems haven’t been compromised — and can be scheduled, event-driven, or expanded to wider office environments.
Residential Bug Sweeps
Designed for executives working from home, sensitive-data teams, and individuals facing elevated risk. Residential TSCM focuses on home offices, private living areas, garages and vehicles — where consumer networks and smart devices can create a larger attack surface.
TSCM
For environments where threats are persistent, mobile or time-sensitive. These services extend beyond “point-in-time” sweeps to protect meetings and detect ongoing activity — including insider threats and burst transmissions.
Government Advanced TSCM
Advanced counter-surveillance for government facilities, operations and officials where espionage risk is elevated and assurance must be defensible. Services support sensitive briefings, inter-agency activity, temporary venues, and protection for government fleets and residences.
COMSEC
Communications Security (COMSEC) focuses on communications data protection and communications threat mitigation — ensuring what you say or transmit cannot be intercepted, manipulated or spoofed by an adversary.
