In short

Counter-surveillance establishes whether you are being watched, by whom and how. It combines counter-observation in the field, sweeps of vehicles and premises for trackers and bugs, a review of devices for spyware, and a plan to reduce the traces you leave yourself. Findings are documented so they can be used in harassment or stalking proceedings.

Trust experts who can stop surveillance before it compromises your security.

How to Recognize That Someone May Be Following or Monitoring You

Surveillance or monitoring can take many subtle forms – from physical observation, through electronic monitoring, to online cyber-tracking. Early recognition of such activities can help prevent serious consequences, including information leaks, data theft, blackmail, or reputational damage.

Common warning signs that you may be under surveillance:

  • recurring vehicles or individuals appearing repeatedly in your surroundings
  • unusual interference in electronic devices
  • unexpected connectivity or battery issues on your phone
  • suspicious emails, links, or files
  • noticeable changes in the behavior of people around you after private meetings or conversations

Do not ignore warning signs – discreet counter-surveillance measures can confirm or rule out potential threats.

Protective Measures Against Surveillance and Monitoring

Detectum uses integrated counter-surveillance methods that combine field analysis, technological tools, and digital investigation. Our goal is not only to detect threats but also to restore a full sense of personal and business security.

Protective actions include:

  • monitoring and analysis of surroundings for signs of surveillance
  • inspection of rooms, vehicles, and mobile devices
  • analysis of digital networks and wireless connections
  • identification of individuals or entities potentially involved in surveillance
  • development of individualized security procedures

Effective privacy protection requires knowledge, experience, and complete discretion-exactly what Detectum provides.

Neutralization of Listening Devices and Surveillance Equipment

Listening devices, directional microphones, GSM recorders, or hidden cameras concealed in everyday objects are only some of the tools used to obtain information illegally. The Detectum team has experience in detecting and neutralizing surveillance devices in offices, vehicles, and private residences.

As part of neutralization services, we perform:

  • radio signal and frequency analysis
  • detection of active and passive listening devices
  • inspection of conference rooms, offices, and vehicles
  • security assessment of communication systems and Wi-Fi networks
  • preparation of a security report with recommendations

Neutralizing surveillance devices is not only about technology- it is about experience and procedures that guarantee effectiveness.

Preventing Surveillance - Security Begins with Awareness

The best method of protecting privacy is prevention. Detectum offers training and consultations in personal and information security, helping clients recognize threats and effectively counter them.

Preventive programs include:

  • risk assessment and identification of habits that may facilitate surveillance
  • implementation of secure communication practices
  • protection of mobile devices and personal data
  • verification of contractors and business environments
  • periodic private and corporate security audits

An informed user is the most effective barrier against surveillance and eavesdropping.

Frequently asked questions

Counter-surveillance — questions and answers

How can I tell if someone is following me?

Warning signs include the same vehicle appearing in different places, repeated chance encounters with the same person, others knowing plans you never shared, unusual phone behaviour and traces of tampering in your car. Certainty comes only from counter-observation conducted by a detective.

How does counter-surveillance differ from bug detection?

Bug detection is a sweep of a specific place. Counter-surveillance goes further: it establishes whether you are being followed in the field, by whom and by what methods, combining counter-observation, vehicle and device sweeps and analysis of your own digital traces.

Can you establish who ordered the surveillance?

Sometimes. Counter-observation can identify the person or vehicle conducting the surveillance, and further enquiries may lead to whoever commissioned it. This cannot be guaranteed in advance — it depends on how professionally the other side operates.

Can the material be used in a stalking case?

Yes. Documentation with dates, places and photographs is standard material in harassment cases under Polish criminal law and in applications for restraining orders.

What can I do before I call?

Write down dates, times, places and descriptions — registration numbers, appearance, circumstances. Do not confront anyone and do not remove any device you find. A chronological note is the best possible starting point.
