Government, Commercial or Corporate TSCM Training?

The need for effective Technical Surveillance Counter-Measures (TSCM) training has never been greater. Whether you require commercial, government or corporate TSCM training courses, we’ve got it covered. Whether operating in the private sector or within government environments, organisations must ensure they are equipped to detect and counter technical surveillance threats at the appropriate level.

At Verrimus, in collaboration with SIASS – Technical Surveillance Services, we provide structured TSCM training programmes tailored to three distinct sectors: commercial, corporate, and government. Each course is specifically designed to meet the operational requirements, threat profiles, and responsibilities associated with these environments.

Tailored Training for Defined Operational Needs

We recognise that TSCM is not a one-size-fits-all discipline. As such, our training is carefully segmented:

Commercial and Corporate TSCM Training

Our commercial and corporate courses focus on equipping practitioners with the skills required to detect, identify, and precisely locate all forms of COTS (Commercial Off-The-Shelf) technical surveillance devices.

These programmes are ideal for:

  • Private investigators
  • Close protection operatives
  • Security professionals
  • Organisations seeking to build internal awareness and capability

Participants will gain practical, hands-on experience in real-world detection methodologies, ensuring they can effectively counter the most commonly deployed surveillance threats.

All attendees on commercial and corporate courses are required to sign non-disclosure and ethical conduct agreements, ensuring that the knowledge and techniques delivered are applied responsibly and professionally.

Expanding Professional Capability

If you are currently offering TSCM services to your client base, or looking to do so, we encourage you to engage with:

SIASS – Technical Surveillance Services, who now provide COMMERCIAL TSCM training in collaboration with ourselves.

This pathway is specifically designed to help independent practitioners and service providers enhance their technical capability and credibility in the field.

Supporting Organisational TSCM Capability

For organisations seeking to establish, develop, or maintain an in-house TSCM capability, or for those responsible for procuring external TSCM services, we recommend engaging with:

SIASS – Technical Surveillance Services, who now deliver CORPORATE TSCM training in collaboration with ourselves.

These courses are structured to support organisational resilience, procurement awareness, and internal capability development, ensuring that businesses can confidently manage their technical surveillance risk.

Government and High-Threat Environment Training

For those operating within military, law enforcement, or government TSCM teams, the threat landscape is significantly more advanced.

Our government-level training, delivered through the Verrimus TSCM Training Centre, addresses higher-level threats and sophisticated surveillance attacks, providing the depth of knowledge and operational capability required in national security and high-risk environments.
