TSCM audit services for organisations and individuals
A professional technical surveillance countermeasures audit finds covert listening devices, hidden cameras, and compromised networks before your strategy, negotiations, or private life leave the room. Delivered by TSCM Partners with documented findings and indicative pricing upfront.
Why organisations commission TSCM audits
The problem
Covert listening devices, compromised networks, and insider-placed hardware can expose strategy, negotiations, and personal safety — often with no visible sign of breach. Most organisations only discover a problem after sensitive information has already left the room.
How an audit solves it
A TSCM audit combines RF sweeps, physical inspection, and cyber-adjacent checks in one measured engagement, scoped to your site and not sold on fear. The same operational standard applies to a corporate facility or a private residence.
Why TSCM Partners
Discreet teams, documented findings, and a clear next step — not a generic security pitch. Indicative pricing upfront, a named follow-up, and engagements built for environments where confidentiality actually matters.
What a professional TSCM audit covers
Every engagement is scoped to the site and threat profile, but a full technical surveillance countermeasures audit draws on six core capabilities.
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.
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.
