About Acoustic Security
We help organisations control speech privacy and stop acoustic leakage in commercial environments.
We measure speech privacy and acoustic leakage in commercial workplaces, then prescribe masking, treatments, or device controls sized to the rooms you already have. The work sits at the intersection of acoustics, on-site measurement, and practical countermeasures for boardrooms, meeting suites, and sensitive facilities.

Leadership
Marko Tuisk
Director, TSCM Partners Ltd / Acoustic Security
Marko is the director of TSCM Partners Ltd, the UK company behind Acoustic Security. The practice is diagnose-first: measure speech privacy and leakage paths before prescribing masking, treatments, or device controls. The company is registered in Reading, England, and serves commercial sites across the UK and selected US markets.
Practice focus
We work on commercial speech privacy, acoustic leakage measurement, attack-vector isolation, and microphone risk in workplaces and sensitive facilities. Engagements are grounded in on-site measurement and reporting you can defend internally, not generic product quotes.
Commercial references
Client identities are withheld by agreement. For serious procurement we can introduce a named contact under NDA.
Financial services headquarters, South East England
Speech privacy audit across executive boardrooms and adjacent open plan. Mapped transmission paths, documented adjacency risk, and prescribed a delivery level before any masking install. Facilities used the report for internal compliance sign-off.
Engagement: speech privacy audit · Year: 2025 · Permission: anonymised
Professional services office, Greater London
Existing sound masking system had drifted after a fit-out. Performance verification, zone retune, and handover notes so the client kept the install without a strip-out or rebuild.
Engagement: sound masking support · Year: 2025 · Permission: anonymised
Named commercial references are available on request after an initial conversation. Contact us and say you need a reference check.
How we work
Diagnose first: audit or measure when the leakage path is unclear. Prescribe next: recommend solution paths and delivery levels sized to your rooms. Deploy or maintain: design, install, retune, or integrate through bookable services once scope is agreed.
Where we work
In the United Kingdom we serve commercial sites across England, Scotland, and Wales, with tiered coverage from major cities to regional estates. See service areas for counties and cities. In the United States we work with commercial clients on the same acoustic lane: speech privacy, leakage control, and device risk. View service areas.
Acoustic lane vs full TSCM
Acoustic Security stays in the acoustic and speech-privacy lane: measurement, masking and treatments, attack-vector isolation, mic nullification, and device custody. We do not sell general RF TSCM sweeps, SCIF build, or cyber device management as our core offer. Where your threat model needs full RF technical surveillance countermeasures or facility accreditation programmes, we partner rather than over-promise.
RF handoff: TSCM Partners · SAPP Security. After diagnose, proximity-risk and independent review: TSCM Risk · TSCM Audit.
Privacy and confidentiality
Enquiry details and site information you share with us are used only to respond and scope work. They are not sold. Floor plans and vulnerability notes are treated as confidential.
NDA before site visit
A mutual NDA is available before any site visit, drawing exchange, or detailed discussion of acoustic vulnerabilities. Request it via Contact.
