Counter-Surveillance and Bug Sweeps (TSCM)

Detecting Hidden Threats. Restoring Your Security.

Concerns about covert surveillance can arise when confidential information becomes known unexpectedly, an unexplained device is discovered or sensitive conversations appear to have been overheard.

Conflict International provides professional Technical Surveillance Counter-Measures, commonly known as TSCM or bug sweep services, for individuals, businesses, legal advisers and organisations concerned about unauthorised monitoring.

Our work may include the examination of offices, boardrooms, residences, vehicles and other sensitive environments for potential listening devices, hidden cameras, tracking equipment and related surveillance risks.

Every assignment begins with an assessment of the circumstances, the environment involved and the information believed to be at risk.

What is a professional bug sweep?

A professional bug sweep is a structured physical and technical examination designed to identify indicators of covert surveillance.

The work may involve:

  • Examining rooms, fixtures, furniture and accessible infrastructure.
  • Assessing radio-frequency activity within the environment.
  • Checking for electronic components that may not be visible externally.
  • Reviewing telephone, network and electrical areas where appropriate.
  • Inspecting vehicles for potential tracking or recording devices.
  • Looking for concealed cameras and unusual modifications.
  • Assessing vulnerabilities that may allow future surveillance.

No single piece of equipment can reliably identify every possible threat.

A proportionate TSCM examination therefore combines specialist equipment, physical inspection, technical analysis and an understanding of how covert devices may be installed or concealed.

For a detailed explanation of the process, read What Is a Bug Sweep (TSCM)? Your Essential Guide to Counter-Surveillance and Protecting Privacy.

When should you consider a TSCM sweep?

A bug sweep may be appropriate where there is a specific concern or where the consequences of information loss would be serious.

Common circumstances include:

  • Confidential information becoming known to an unauthorised person.
  • Sensitive negotiations or legal discussions taking place.
  • An unexplained object or device being discovered.
  • Signs of unauthorised entry or interference within a room or vehicle.
  • A relationship, employment or commercial dispute creating a credible surveillance concern.
  • A senior executive or high-profile individual facing an elevated threat.
  • A board meeting, acquisition or strategic discussion requiring a secure environment.
  • A vehicle behaving unusually or showing signs of interference.
  • A residence or hotel room requiring examination after a specific concern.

An unusual noise, poor telephone connection or rapidly draining battery does not by itself prove that surveillance is taking place.

The circumstances should be assessed before deciding what form of technical examination is proportionate.

Environments we can examine

Corporate offices and boardrooms

Commercially sensitive environments may contain strategic plans, client information, intellectual property and confidential negotiations.

A corporate TSCM assignment may cover:

  • Boardrooms.
  • Executive offices.
  • Meeting rooms.
  • Legal and compliance areas.
  • Research and development facilities.
  • Temporary project offices.
  • Conference and negotiation spaces.

The scope should reflect how the room is used, who has access and what information may be at risk.

Private residences

Residential concerns may arise during relationship disputes, stalking, harassment, litigation or following unexplained access to the property.

A residential examination can consider areas where conversations take place and locations where a device could reasonably have been installed.

We approach residential matters discreetly and avoid making assumptions about who may be responsible.

Vehicles

Vehicles may be examined where there is a concern about location tracking, audio monitoring or physical interference.

The work may consider:

  • Accessible interior areas.
  • Exterior mounting points.
  • Power sources.
  • Common concealment locations.
  • Potential GPS or cellular tracking equipment.
  • Unexplained additions or modifications.

Vehicle examinations cannot guarantee that every possible device will be located, particularly where access is restricted or equipment has already been removed.

Hotels and temporary meeting spaces

Hotel rooms, rented offices and conference facilities can create additional risks because many people may have access before an important meeting takes place.

Where appropriate, TSCM support can be arranged before confidential discussions, negotiations or executive travel.

How a TSCM assignment works

Initial threat assessment

We begin by discussing:

  • What has caused the concern.
  • What information may have been exposed.
  • Which rooms, vehicles or locations are involved.
  • Who has had access.
  • Whether anything unusual has been discovered.
  • Whether there are immediate safety, legal or cyber-security concerns.

This helps determine the appropriate scope and avoids unnecessary work.

Planning and preparation

The timing of the examination may be important.

In some cases, the environment should remain undisturbed until the team arrives. In others, urgent account security or police involvement may take priority.

We will explain any practical preparation required before attendance.

Physical and technical examination

The precise methodology depends on the environment and assessed risk.

Equipment may include:

  • Radio-frequency spectrum analysis tools.
  • Non-linear junction detectors.
  • Thermal-imaging equipment.
  • Optical examination tools.
  • Cellular and wireless-signal analysis equipment.
  • Specialist vehicle-search equipment.

Equipment supports the examination, but findings must be interpreted in context. Normal communications systems, building infrastructure and neighbouring signals can all create activity requiring further assessment.

Findings and recommendations

Following the examination, we explain the findings and any limitations affecting the work.

Recommendations may include:

  • Further examination of a specific area.
  • Changes to room access or meeting procedures.
  • Improved physical security.
  • Cyber-security review.
  • Digital-forensic examination of a device.
  • Ongoing monitoring or periodic sweeps.
  • Preservation of a suspected device for legal or police purposes.

A TSCM sweep provides an assessment of the environment at the time it is conducted. It cannot guarantee that surveillance has never occurred or that a device will not be installed later.

TSCM and digital-device concerns

A physical bug sweep is not the same as a forensic examination of a phone, computer or online account.

Where the concern involves:

  • Unauthorised email access.
  • Spyware or malicious software.
  • Compromised cloud storage.
  • Unfamiliar account sessions.
  • Stolen passwords.
  • Suspicious forwarding rules.
  • Remote access to a device.

Separate cyber-security or digital-forensic support may be required.

The initial threat assessment should establish whether the concern is environmental, digital or potentially both.

UK and international coverage

Conflict International is based in London and supports clients across the United Kingdom.

Assignments may be arranged in offices, residences, vehicles, hotels and temporary meeting facilities.

International deployment may also be available, subject to the location, local legal requirements, timescale and scope of work.

We do not promise immediate deployment in every case. Availability depends on the circumstances and the resources required.

Why instruct Conflict International?

Clients instruct Conflict International where the matter requires a discreet, structured and proportionate response.

Our approach includes:

  • Threat-led scoping rather than applying the same process to every environment.
  • Physical and technical examination using specialist equipment.
  • Clear explanation of findings and limitations.
  • Discreet coordination with the client and relevant advisers.
  • UK and international capability where circumstances permit.
  • Recommendations addressing both immediate findings and future risk.

We do not assume that every concern confirms the presence of surveillance.

The purpose of the assessment is to examine the available evidence, identify relevant indicators and help the client decide what action is proportionate.

Discuss your TSCM requirements

The most useful initial information includes:

  • The location and type of environment.
  • The reason for the concern.
  • The approximate size of the property or office.
  • Any suspected device or area of interest.
  • The dates on which information may have been exposed.
  • Whether a vehicle is involved.
  • Any immediate safety or legal concerns.

If you are concerned that an office, residence, vehicle or sensitive meeting space may be subject to unauthorised surveillance, contact Conflict International in confidence to discuss the appropriate scope and next steps.
