Technical Surveillance Countermeasures (TSCM) are techniques and methods used to detect and counter technical surveillance—including unauthorized listening/recording devices and other technical security hazards that allow information to be accessed or removed without authorization.

In practical terms, a TSCM inspection is a methodical evaluation of offices, boardrooms, residences, vehicles, and other sensitive spaces to identify covert threats such as hidden microphones/cameras, suspicious devices, rogue wireless activity, and technical weaknesses that enable eavesdropping.

Yes. TSCM is the professional discipline behind what many call bug sweeps or electronic sweeps, focused on detecting and countering technical surveillance and related hazards.

• Hidden microphones and recorders

• Concealed cameras and covert imaging devices

• Wireless surveillance and rogue transmissions (including suspicious Wi-Fi / RF activity)

• Technical security hazards that allow information to leak through unauthorized technical means

Skye-Global is a security and risk-management provider trusted for high-stakes environments and protective programs. We offer a specialized service that utilizes TSCM as a standalone product offering within our holistic approach of risk mitigation and plan development.

Our TSCM capability is built for clients who need:

• Discretion and professionalism in executive and corporate settings

• Operationally practical recommendations (not generic advice)

• Integration with broader security programs (executive protection, travel security, risk assessment, and site security planning)

Certified / qualified operators: Skye-Global deploys trained, vetted TSCM operators who maintain professional training and certifications aligned with modern TSCM tools and methodology. (Certification details and scope of services available upon request.)

When information is valuable, it becomes a target—especially during moments that are market-moving, litigation-sensitive, or reputation-critical.

Organizations most often schedule TSCM support for:

• Board meetings, executive offices, and secure conference rooms

• Mergers, acquisitions, divestitures, and other high-stakes negotiations

• Litigation, pre-litigation strategy, internal disputes, whistleblower matters

• Executive protection programs (home/office/travel environments)

• Hotels, off-site meetings, aircraft/vehicles, and temporary workspaces

A single compromised conversation can impact: valuation, legal posture, IP protection, operational security, and personal safety.

TSCM reduces risk through layered detection and technical verification; no provider can responsibly guarantee detection of all hypothetical threats. The value is a disciplined program that identifies evidence, anomalies, vulnerabilities, and mitigation actions aligned to your risk profile.

Step 1: Confidential intake (scope, locations, threat context, timing)
Step 2: On-site inspection (discreet workflow; minimal disruption)
Step 3: Outbrief (same day when possible)
Step 4: Written report (risk-ranked findings + mitigations)
Step 5: Optional continuity plan (scheduled inspections for key spaces/events)

• Corporate leadership teams and boards

• Legal teams and compliance leaders

• High-net-worth individuals and family offices

• Critical infrastructure and sensitive industrial operations
