GABRIEL

RF IN PLACE MONITORING SYSTEMS

Advance Screen for Baseline and Alarm

GABRIEL is a passive, user friendly, cost effective Radio Frequency (RF) IPMS. It is designed to alert you to the use of intentional, unintentional, and unauthorized potentially malicious wireless transmissions in your secure space. This proprietary technology was developed to be deployed in a Secure Work Environment™ (SWE) such as a boardroom, secure area, or data processing center.

The system will alert you to the unauthorized use of mobile wireless devices such as cell phones, laptops, tablets other Portable Electronic Devices (PED’s). It can also detect the use of electronic eavesdropping technology (bugs). GABRIEL is unique in its ability to completely cover the full RF spectrum and at speeds designed to catch stealthy burst transmissions from sophisticated eavesdropping devices

SWE™ Secure Work Environment

Unlike most available sensors that only monitor or scan specific bands, GABRIEL covers the entire spectrum. Alerting in the CELL, Wi-Fi, and Other categories.

GABRIEL is an innovative monitoring capability that allows non-technical users to easily set up and monitor their Secure Work Environment (SWE™). All required software and hardware is included. System functionality (plug & play), operates on Microsoft® Windows 10 environment. The software comes standard on a tablet PC platform but can also be loaded to laptops with sufficient processing speed and enhanced USB requirements.

The system allows the user to effectively monitor and be alerted when RF energy is introduced into a SWE™. Gabriel can also alert to low level TEMPEST signals if desired.


Currently, Gabriel is a stand-alone device. It can be wall mounted inside the SWE™ and/or in a vestibule for entry screening.

Gabriel can be designed and configured to be remotely monitored and controlled via network application. This approach is customized to your network architecture and communicate with your Network Operations Center or Security Operations Center.

GABRIEL eliminates the significant investment and technical expertise required to replicate its capability. You no longer need to use an expensive spectrum analyzer and a signals engineer to monitor your space 24-7.

RF Defense's goal is to protect your organization from having its valuable Intellectual Property (IP) from being compromised. In a time of increasing risk, it is imperative that you shield against unauthorized and unintentional wireless transmissions in addition to your physical and IT security posture.
