Technical Surveillance Counter-Measures

How much is your information worth?

Counter Intelligence Solutions Group, Inc. specializes in Technical Surveillance Counter-Measures (TSCM). TSCM is also referred to as a sweep service. Our sweeps will search and locate any hidden transmitters, telephone taps, video cameras, microphones, and other recording devices. We are the licensed experts in the TSCM industry, and our staff licenses other TSCM operators all across the globe. Don't be fooled by $200 RF Detectors that only search 5% of the frequency spectrum, or by the telephone tap detection devices that rely on voltage drops to find taps. It takes a well-trained professional to perform a complete sweep service, and that is who we are.

Sweeps are divided into three parts. Part I includes an Electronic Security Survey (ESS), and is designed to be a systematic search of the entire radio frequency spectrum. We identify all receivable transmissions and discern the presence of any unauthorized or covert transmissions to include frequency hopping, subcarriers and spread spectrum. Each hallway/room/office, including vents, ducts, equipment/furniture will be swept. Frequencies up to 40GHz will be fully searched and inspected.

Part II is the Countermeasure Testing of Telephones and Telephone Lines (CTTTL). All phones and phone lines will be electronically tested using the CCTA-1000 or a Time Domain Reflectometer. Telephone canalization is conducted from the basement or frame room of a facility up to every phone, fax and computer instrument. All telephones on the premises will be tested electronically, dismantled and inspected for foriegn devices and nonstandard wiring, including a search for any hook switch compromise, which allows the room to be "heard" when the phone is not being used.

Part III is a physical search that covers the entire designated area. This includes checking for unusual wiring as well as all standard wiring in the designated area.

Our final report will include an evaluation of existing security measures and procedures currently in use. This includes access control, video surveillance, perimeter security, building and mailroom design, as well as executive protection programs. The CISG Sweep Team is ready to solve your eavesdropping problems. Your confidentiality is assured.
