Kestrel TSCM ® Professional Software | Signals Intelligence Support System (SISS)

Powerful Software Defined Radio (SDR) Spectrum Analytics Software

The Kestrel TSCM ® Professional Software is a powerful and flexible operator centric software defined-radio application ideal for advanced radio-frequency spectrum monitoring. Algorithmic dimensional geo-location heat mapping developed on the principles of an integrated standards-based RF propagation model, significantly enhances Probability of Detection (POD) and Probability of Intercept (POI) at the operational level.

“We are a Canadian Corporation with a Global Reach…”

The Kestrel TSCM ® Professional Software leverages the most advanced RF sensor-based Software Defined Radio (SDR) hardware technology, and provides functionality far beyond that found in typical commercial spectrum analyzers and includes the ability to provide unintentional radiator (TEMPEST) detection, identification and evaluation of emissions.

Kestrel ® embodies unique capabilities that make it particularly attractive for Technical Surveillance Countermeasures (TSCM) and Signals Intelligence (SIGINT) applications, including a wide range of spectrum monitoring and advanced geo-location heat mapping applications, across commercial, and national security interests.

The Kestrel TSCM ® Professional Software is ideal for the intelligence community, executive protection, counter terrorism, managed Remote Spectrum Surveillance and Monitoring (RSSM) TM, and many other demanding applications within law enforcement, government, military, space, and spectrum regulatory agencies.

Securing the Electro-Magnetic Spectrum in a Modern Moving Target Threat Model

The Kestrel TSCM ® Professional Software is an advanced operator centric SDR application optimized for TSCM and similar professional radio-frequency and power line monitoring applications. Kestrel ® brings an array of extraordinary features that are expertly designed to bring the TSCM professional technical operator back into the analytical equation.


The resultant synergies greatly improve effectiveness in comparison with typical industry modified spectrum analyzers.

Kestrel ® provides unique features and functionality for use within a real-time live threat environment, particularly useful for private sector and corporate security teams conducting counter-espionage related technical security operations for all known and emerging threat technology.

The Kestrel TSCM Professional Software | Signals Intelligence Support System provides unique features that include advanced dimensional geo-location heat mapping, ideal for locating all radio-frequency energy across a complex Operator Defined Target Area (ODTA) TM including the ability to detect, identify and resolve TEMPEST related unintentional radiation. The ability to utilize algorithmic heat mapping for power line threat technology identification, analysis and localization is a standard included proprietary feature.

Professional Development TSCM Group Inc., provides the only standards-based Software-Defined Radios (SDR) application that includes TSCM specific features and functionality, developed from the ground up to meet the challenges of a modern moving target threat model.

Kestrel ® includes industry leading support for the FCC (USA), IC (CAN), and ACMA (AUS) official licensing frequency databases at the software level in the form of Frequency Database (FDB) TM files and includes a powerful Operator Frequency Database (OFD) TM technology.

“The competition tells its potential customers that the problem with the Kestrel TSCM ® Professional Software, is that it captures too many signals – Inexplicably Ironic…”

There is a growing requirement and urgency for advanced TSCM | SIGINT capabilities, such as those provided by the Kestrel TSCM ® Professional Software. Industry, government organizations, military and national security entities, including private individuals, face a host of increasingly formidable security threats from a wide-range of practiced threat actors.

Technical advances and market forces have made available inexpensive consumer devices of astonishing sophistication that can be readily adapted for illicit surveillance. Surveillance can even be carried out by compromising wireless devices owned by the victim. The threat is no longer limited to a few hostile nation state actors; it could be virtually anybody.

Kestrel ® reflects decades of practical experience and its progressive development ensures it will continue to meet the evolving needs of TSCM and other professionals. The experience and real-world needs of professionals like you, continue to drive the future evolution of the Kestrel ® software development process

Technical operators have been complaining for years about the lack of mission specific features and functionality required in the field; they now have the opportunity to influence the development of tools and features that they will benefit from in the future.

Whether the requirement is strictly TSCM, detecting drones or analyzing drone radio-frequency signals, deploying drones for dimensional geo-location heat mapping, working in a SIGINT role, or deploying for mobile, fixed-station, or facility level technical security spectrum monitoring, the Kestrel TSCM Professional Software covers all of the essential technology checklists, with powerful innovative new technology.
