Technical Surveillance Countermeasures (TSCM): What to Know

You may never need TSCM, but if you do, it’s already too late.

Technical Surveillance Countermeasures (TSCM), often called “bug sweeps,” are specialized procedures used to detect and neutralize hidden surveillance devices. These include microphones, cameras, GPS trackers, and other tools used to capture private information without consent.


Who Needs TSCM Services?

TSCM isn’t just for government agencies or high-profile executives. We’ve conducted sweeps for:

  • Law firms handling sensitive litigation
  • Corporations involved in mergers or IP development
  • Executives experiencing targeted harassment or leaks
  • Individuals in high-risk personal situations

If you suspect your privacy is being compromised or if you’re handling information someone might want to intercept, TSCM may be warranted.


What TSCM Involves

Professional TSCM sweeps typically include:

  • RF (radio frequency) spectrum analysis to detect wireless transmissions
  • Physical inspection of offices, conference rooms, or vehicles
  • Analysis of phone systems, wiring, and suspicious objects
  • Documentation of findings and guidance on next steps

If suspicious devices are found, we assist in coordinating with legal counsel or law enforcement as needed ensuring evidence is preserved and chain of custody is maintained.

The goal isn’t just to find bugs, it’s to restore peace of mind and provide a clear, defensible path forward.


Discretion Is Everything

Because TSCM often involves sensitive concerns; internal investigations, family conflicts, legal exposure, discretion and professionalism are paramount.
