Counter-/Anti-Surveillance Course

Our Counter- / Anti-Surveillance (CS/AS) Course offers the most effective and proven methods for early detection and potential counter of hostile surveillance and observations. Our CS training courses can be adapted to meet the specific needs and requirements of the client and are unparalleled in its kind; our training courses are provided by highly experienced specialists.

The CS/AS training course focuses on the following skills:

  • Reducing the chances of terrorist and/or criminal activities against an asset or an individual.
  • Increasing the chances of recognizing and detecting hostile surveillance and reconnaissance of an asset or individual.
  • Improving knowledge, skills, capabilities, and trust of security professionals in detecting suspicious activity.
  • Reducing the risk of kidnapping and other criminal and/or terrorist actions directed against a person(s), by applying anti-and counter-surveillance and the so-called ‘best practices in the field of security'.
  • Increasing individual self-confidence by raising awareness among staff and introducing proven skills and procedures specifically designed to detect surveillance and alert them to suspicious activity.
  • Improving the professional and security image of your organization.


In the Counter-/Anti-Surveillance Course, tactics and techniques are taught of which the application may be sensitive. TGA will only transfer the knowledge to persons and companies that have been pre-screened by TGA. Anyone wishing to participate in the course must be in possession of a Certificate of Good Conduct (VOG) and must further participate in a telephone screening interview and background study. If the outcome is positive, you can be registered for the relevant study program.
