Technical surveillance countermeasures

TSCM

Home brand: RF sweeps, physical inspection, and cyber-adjacent checks for boardrooms, facilities, and private venues.

We detect and defeat covert listening devices, compromised networks, and insider-placed hardware. Engagements are scoped to your site: measured work, not fear-led pitches.

Role: Acoustic. Complementary specialist. Where TSCM addresses electronic and physical surveillance, Acoustic Security closes the speech-privacy lane: leakage paths, sound masking, and microphone risk.

Retrofit speech privacy without rebuilding interiors. Audits, sound masking, vendor-orphaned system care, and microphone nullification for workplaces that need confidentiality beyond a sweep.

Our London location microsite: corporate, cyber threat assessment, and residential paths for Greater London work, delivered by the same TSCM Partners team.

Use tscmlondon.co.uk when the brief is Greater London. Book locally or through the main TSCM Partners contact form; coverage, method, and office details are on the London site.

Our Birmingham location microsite: corporate, cyber threat assessment, and residential paths for Birmingham and the West Midlands, delivered by the same TSCM Partners team.

Use tscmbirmingham.co.uk when the brief is Birmingham or the West Midlands. Book locally or through the main TSCM Partners contact form; coverage, method, and office details are on the Birmingham site.

Our Estonia market site: services and audience solutions in Estonian, with clear boundaries (countermeasures, not surveillance).

Use tscm.ee for Estonia-facing briefs. Technical checks, office inspections, audits, and virtual research - booked through the same TSCM Partners team.

Our dedicated inspection practice: documented physical, RF, and network inspections of boardrooms, offices, and residences across the UK, Europe, and the US.

Where procurement, legal, and facilities teams specify a TSCM inspection rather than a bug sweep, this is the same TSCM Partners team delivering a scoped, reported inspection, methodology, coverage, and indicative pricing are set out on the site.

Role: Risk. Governance practice of TSCM Partners. Where this site delivers sweeps and inspections, TSCM Risk owns risk assessment, risk-register wording, sweep-frequency programmes and compliance mapping for the board and ISMS.

TSCM risk assessments, openly published programme frameworks (policy, risk register wording, sweep frequency, board reporting), and compliance guidance mapping NIS2, ISO 27001, the UK Corporate Governance Code and UK GDPR to technical surveillance risk.

Role: Audit. Structured technical audit and assurance content for procurement, compliance and board reviews. Complements Partners fieldwork and Risk programme design with audit-ready evidence, not another sweep vendor.

Guides and engagement framing for security and compliance audits around technical surveillance, the evidence layer when ISMS owners and auditors ask what was checked and how often.

Role: SAPP. Operational home for proximity attack-surface programmes. Where Partners books the hub engagement, SAPP delivers proximity threat management beyond the classic room sweep.

Proximity threat management and PASM delivery for executives, travel and venues, the layer that sits beside continuous TSCM when the risk is not only inside one boardroom.

Role: Marko. Published frameworks (including PASM) that programme design aligns to. Not a fieldwork vendor, the reference layer Risk, SAPP and Partners programmes cite.

Framework documentation for proximity attack surface management and related technical surveillance programme design, use when you need the published method, not an on-site sweep.
