Audit-ready TSCM evidence for Risk and Audit Committees
Technical surveillance countermeasures audits that produce control effectiveness findings, independent third-party review, and a retained report your board pack can use — ISMS-aligned assurance without turning a room inspection into a full risk programme. Delivered by TSCM Partners.
What oversight bodies actually need
Large organisations do not buy “bug sweeps.” They buy assurance that survives committee scrutiny. This site exists for that deliverable.
Control effectiveness
A dated assessment of whether technical surveillance controls on scoped spaces are operating as intended — language Risk and Audit Committees already use for other assurance work.
Independent third-party review
External specialists, not an internal walk-through. Findings are framed for oversight: what was in scope, what was tested, what was found, and what remains open.
Retained report
A board reporting pack you keep: scope, method, residual risk, and remediation priorities. Usable by internal audit, legal, and insurers — not a verbal all-clear.
Methods behind the evidence
The report is the product. The tools below are how it is produced — scoped to the site and threat profile, not sold as a gadget catalogue.
RF spectrum analysis
Broadband radio-frequency survey of the site to detect active transmitters, GSM/LTE devices, Wi-Fi and Bluetooth implants, and burst or frequency-hopping bugs.
Physical inspection
Methodical hands-on examination of furniture, fittings, wiring, sockets, ceiling voids, and vehicles for concealed devices, including dormant and hard-wired hardware.
Non-linear junction detection
NLJD equipment locates semiconductor electronics even when a device is switched off, out of battery, or deliberately silent — the threats a simple scan misses.
Wi-Fi and network checks
Identification of rogue access points, unauthorised devices on the network, and cyber-adjacent vulnerabilities that turn IT infrastructure into a listening post.
Thermal and visual imaging
Thermal cameras and optical lens detection reveal powered devices behind surfaces and pinhole cameras that are invisible to the naked eye.
Documented findings
Every audit ends with a written report: what was inspected, what was found, the risk assessment, and clear remediation steps with a named follow-up contact.

TSCM audit questions, answered
What is a TSCM audit?
A TSCM audit (technical surveillance countermeasures audit) is a professional inspection of a building, room, vehicle, or network to detect covert listening devices, hidden cameras, GPS trackers, and other illicit surveillance technology. It combines RF spectrum analysis, physical search, non-linear junction detection, and network checks, and concludes with a documented report of findings and remediation steps — evidence a Risk or Audit Committee can retain.
How much does a TSCM audit cost?
Corporate TSCM audits are typically priced per square foot or per room, with engagements commonly ranging from around $2 to $5 per square foot in the US and comparable rates in the UK and Europe. Residential audits often start from a flat fee. The final quote depends on the size of the site, the complexity of the electronic environment, and your threat profile. TSCM Partners provides indicative pricing upfront before any engagement.
How often should a TSCM audit be carried out?
High-risk environments such as boardrooms, deal rooms, and R&D facilities are usually audited quarterly. An annual audit is a prudent baseline for general corporate offices. Additional audits are recommended before sensitive meetings, after building work or personnel changes, following a suspected breach, and during mergers, acquisitions, or litigation.
Who carries out the audit?
All audits arranged through this site are delivered by TSCM Partners: discreet, experienced technical teams using professional-grade equipment, operating across the United Kingdom, United States, and Europe for both commercial and private clients.
Is a TSCM audit the same as a bug sweep?
A bug sweep is one component of a TSCM audit. A full audit goes further: it includes physical inspection, detection of dormant devices, network and Wi-Fi checks, an assessment of information-security vulnerabilities, and a documented report — not just a scan for active transmitters.
Is the engagement confidential?
Yes. Discretion is fundamental to the work. Audits can be scheduled outside business hours, teams operate without drawing attention, and findings are reported only to your designated point of contact.
