RF Spectrum Analysis

Radio frequency (RF) analysis involves detecting, analyzing, and locating potentially hostile transmissions, such as those produced by room bugs and GPS tracking devices. RF spectrum analysis is a technical skill that requires knowledge of spectrum allocation, signal propagation, modulation, masking methods, and direction-finding techniques.


Wi-Fi Analysis

Eavesdroppers sometimes use existing or rogue Wi-Fi networks to exfiltrate data, making it important to audit Wi-Fi networks in sensitive spaces. Once potentially rogue networks or clients are identified, they can be located and further assessed.


Wired System Analysis

Ethernet, telephone, AC, and alarm system wiring provide pathways for information to exit a target area. Wires should be traced and electronically inspected to ensure that they are not being used for such purposes.


Ultrasonic Inspection

Ultrasonic sound can be used to secretly transmit information over short distances. Additionally, some eavesdropping devices unintentionally emit detectable ultrasonic noise, making them easier to detect.


Business and residential telephone systems are vulnerable to numerous eavesdropping techniques. We electronically test telephone instruments, trace wiring, and inspect on-site distribution frames and demarcation points for taps. 

Telephone System Analysis


Clients concerned with electronic espionage often overlook a more obvious threat: acoustic leakage. Before dealing with higher level threats, it makes sense to determine if discussions can simply be overheard, sometimes with the aid of special microphones. Various tools can be used to test for and mitigate this threat.

Acoustic Leakage Analysis


Hidden Camera Detection

Covert cameras can be detected through RF analysis, thermal imagery inspection, and special tools that detect semi-conductors and lens reflection.


Equipment Auditing

A thorough equipment audit identifies all the equipment in a workspace and serves as a baseline for subsequent inspections. After the initial audit, it is relatively easy to identify objects later brought into a workspace that might serve as hosts for eavesdropping devices.


Thermal Imagery Inspection

Most eavesdropping devices generate heat. Thermal imagery inspections allow us to identify heat sources that could indicate the presence of eavesdropping devices.


Infrared & Laser Detection

Some eavesdropping devices use light instead of RF to transmit conversations or data. Such devices operate line-of-sight and can only be detected through a physical search or by using specialized tools.
