TSCM & Bug Sweeping Services
Technical assurance for private spaces. A clearly defined brief, discreet coordination and specialist assessment of electronic eavesdropping concerns.
Private homes · Private offices · Confidential conversations
Confidence begins with a well-defined inspection.
A confidential meeting, a change in household access or a specific concern about electronic eavesdropping may justify a technical review. Technical Surveillance Countermeasures (TSCM), commonly called bug sweeping, examines an agreed space for indicators of unauthorised surveillance and relevant technical security weaknesses.
Pegasus Ops defines and coordinates the client brief. A trusted third-party TSCM specialist carries out the technical inspection, testing and reporting. TSCM is the only security service we deliver through a third party; our other security services are delivered by Pegasus Ops. You retain a clear Pegasus point of contact throughout the engagement.
We assess enquiries for London and the wider UK, as well as international requirements. The location, access, specialist availability and practical arrangements are confirmed before an instruction is accepted. The proposal explains who performs the work, what is covered and the limits of the assessment.
Technical assurance shaped around the setting
Residential bug sweeping
A review of agreed rooms or areas within a private home or estate. The brief establishes the property authority, access arrangements and how the inspection can fit around family life. The specialist confirms the appropriate extent of physical and technical inspection.
Private offices and meeting spaces
TSCM can support concerns about confidential discussions in offices, boardrooms or private meeting rooms. The purpose, relevant areas and available working period are agreed, with arrangements for notifying the client of a significant finding.
A specific concern or change in access
An unusual discovery, unexplained information disclosure or change in access may warrant assessment. Begin with a broad description so the appropriate review can be considered. A concern alone does not establish that a surveillance device is present.
Specialist requirements
Vehicles, temporary premises and other settings require an individual assessment of suitability and access. Coverage is confirmed in the written scope. A premises inspection does not automatically include devices, networks, vehicles or unrelated locations.

From the first conversation to a useful technical assessment
01 · Establish the requirement
Share the general setting, timing and reason for the enquiry. Pegasus clarifies who may authorise access, which spaces matter and the purpose of the review.
02 · Confirm the specialist brief
The proposal identifies the third-party technical delivery, scope, fee, expenses, access requirements and reporting arrangements. Work begins only after the instruction is agreed.
03 · Review and act
The specialist explains the findings and limitations. Pegasus helps the client understand how agreed recommendations connect with existing protective arrangements. Any follow-up inspection or additional work is separately scoped.
Connect technical findings with the wider security picture
A technical sweep answers a different question from counter-surveillance, which addresses possible unwanted observation of a principal or location. Threat monitoring and OSINT examines relevant public information. We help identify the appropriate starting point.
Where findings affect a property or private office, the response can connect with residential security, family-office security or a security risk assessment. Each service has its own agreed scope and responsibilities.
Questions before you instruct us
How do I find hidden cameras in a home or office?
Begin with the specific concern, the rooms involved and who can authorise an inspection. An unfamiliar object or unexpected disclosure is a reason to assess the facts; it does not establish that a hidden camera is present. Explain what you observed and when, and agree a private way to discuss the detail.
A quick visual check should not be treated as proof that a space is free from surveillance. FCDO Services’ guidance on hidden cameras recommends that professionally installed devices are handled by TSCM professionals. Pegasus coordinates a defined brief with a trusted third-party specialist, who confirms the inspection methods, findings and limitations.
What does TSCM stand for?
TSCM means Technical Surveillance Countermeasures. In this service it is a specialist technical assessment of agreed spaces for indicators of electronic eavesdropping and related security weaknesses. Bug sweeping is a commonly used term for this work.
Who carries out the bug sweep?
Pegasus Ops scopes and coordinates the engagement. A trusted third-party specialist conducts the technical inspection, testing and reporting. TSCM is our only security service delivered through a third party; the other security services are delivered by Pegasus Ops.
Can a sweep guarantee that a space is secure?
No inspection can provide an unlimited guarantee. Findings relate to the agreed scope, access, conditions and time of inspection. Limitations are explained in the report, and later changes may justify a further review.
Do you offer bug sweeping services in London and internationally?
London and UK enquiries can be assessed, and international requirements are considered individually. Location, permissions, access, specialist availability, travel and reporting requirements are confirmed before work is accepted.
How much do TSCM services cost?
The quote reflects the type and size of the setting, areas in scope, access, working period, preparation, reporting and travel. The proposal explains the fee, expenses and exclusions. Follow-up work is agreed separately.
Is this part of a counter-surveillance engagement?
A technical sweep is a separate instruction from counter-surveillance services. Where both are relevant, the proposal distinguishes the technical specialist’s role from Pegasus’s protective work and explains how findings are shared.
Discuss the setting. Define the right review.
Begin with the general location, timing and purpose of the enquiry. Detailed property information and sensitive concerns can be discussed through an agreed channel after initial contact.
