For those new to Technical Surveillance Countermeasures (TSCM), understanding the fundamentals is essential. TSCM inspections primarily focus on detecting audio eavesdropping and video voyeurism while also identifying vulnerable information security targets. This includes audio, video, and data during creation, transmission, or storage. Successful TSCM inspections ensure confidentiality in business operations, protect personal privacy, enhance security, and strengthen competitive advantages and profitability. Achieving these goals requires a smart strategy, knowledgeable execution, and thorough follow-through. Our guidance facilitates easy and cost-effective planning.
