What Is TSCM

A technical sweep for modern surveillance risks.

TSCM is the professional discipline of inspecting an environment for signs of unauthorized surveillance, recording, monitoring, or electronic collection. A proper engagement characterizes the environment — documenting what’s normal so future changes can be detected faster and with confidence.

Our Approach

Baseline. Verify. Document. Recheck.

Many think of TSCM as a one-time sweep. We treat it as a program — establishing a documented baseline so future surveys answer a better question: what is normal here, and what changed?
