TSCM (Debugging)

Technical Surveillance Counter-Measures (TSCM) is often referred to as debugging, electronic counter-surveillance or bug sweeping. It's function is the discovery, identification, isolation and defeat of eavesdropping or other electronic devices and digital threats.

Please note: For obvious reasons, when contacting us in connection with TSCM, please do not to call from any area or any phone you believe is being monitored - instead, remove yourself from the suspect area and contact us from a sterile phone (perhaps a payphone). Likewise, if you suspect that a particular computer or perhaps an email account has been compromised then you should not use that computer or email to contact us.

What does TSCM entail?

A professional evaluation of a site's technical security posture consists of a thorough visual, electronic, and physical examination in and about the surveyed area, and includes the use of specialized equipment, such as:

  •  Frequency scanners and filters
  •  Spectrum analyzers
  •  Vector signal analyzers
  •  Non-linear junction detectors
  •  Time-domain reflectometers
  •  Portable x-ray machines
  •  Thermal imaging sensors
  •  Oscilloscopes

Best-of-breed TSCM Equipment

Our TSCM consultants are extensively trained, experienced specialists who use only the best-of-breed counter-surveillance and countermeasures equipment. Most of the equipment is supplied by Research Electronics International (a manufacturer of TSCM equipment that is preferred by governments, military, law-enforcement and intelligence agencies across the globe) and all consultants have been tested and certified by the manufacturer.

We are able to arrange ad-hoc or periodic surveys of your establishment, infrastructure and systems, in order to identify and neutralize any eavesdropping threats, protect your sensitive information and improve information and communications security. Although other technology and devices are also used, the following equipment is instrumental in the majority of TSCM surveys:

OSCOR GREEN Spectrum Analyzer

The OSCOR Green is designed for commercial applications to detect illicit eavesdropping signals, perform site surveys for communication systems, conduct radio frequency (RF) emissions analysis, and investigate misuse of the RF spectrum. The OSCOR Green Spectrum Analyzer sweeps 24GHz in 1 second quickly detecting transmitting electronic surveillance devices. OSCOR Green's unique integrated auto switching antenna system requires no extra antennas or cables. At 9.6lbs/4.4kg, OSCOR Green is portable and convenient to operate. The 8.4in/21.3 cm high resolution touch screen display puts "drag" and "move" controls at your finger tips.

TALAN Telephone and Line Analyzer

The TALAN incorporates several types of telephone line tests including common tests such as voltage, current, resistance, and capacitance tests, as well as NLJD, FDR Frequency Domain Reflectometry, and Digital Demodulation technology into a single piece of equipment. Additionally, the TALAN utilizes an automatic internal pair switching matrix to automatically perform tests on all pair combinations. The ability to perform several different tests allows the user to compare the results of multiple tests on multiple phone lines, quickly identifying any potentially threatening anomalies. With new enhancements built into the TALAN software interface, users can now test internet protocol (IP) packet traffic on VoIP phones and systems. VoIP data collected by the TALAN software includes Source and Destination Mac Addresses; header type; statistics - total packets; packet rate; peak rate and run time. Users can also define advanced filtering options. Data can be stored and exported to USB or Flash as data files for further analysis, sharing and reporting.
