Temel Bilgiler
What Is Bug Sweeping (TSCM)?
TSCM (Technical Surveillance Counter-Measures) is the full set of preventive and detective controls applied against technical surveillance risks.
Protection Goal
Aims to prevent critical information assets from leaking through unauthorized listening, monitoring, or recording in physical environments such as boardrooms, executive offices, and R&D areas.
Comprehensive Approach
TSCM is not just "finding devices." The process combines risk analysis, evidence-based assessment, and a remediation plan.
Maturity Uplift
Structured to raise the organization's environment security maturity and sustain it over time.

TSCM engagements can be planned as tek seferlik or periyodik based on the organization's risk level.
- Tek seferlik tarama: Comprehensive check for a specific meeting, process, or area
- Periyodik tarama: Regular schedule for executive floors, R&D, or critical units
- Emergency sweep: Rapid response when suspicion arises

Out of Scope — Important Notice
The TSCM service exists to identify technical risk and improve environment security. Scope boundaries are defined explicitly so corporate processes stay on solid ground:
- It is not a forensic investigation and does not aim to identify perpetrators
- It does not constitute criminal attribution or identification
- Findings are analyzed within a corporate reporting framework and recommendations are provided
- Matters requiring legal action are referred to the competent authorities
Frequently Asked Questions
TSCM Frequently Asked Questions
Frequently asked questions about bug sweeping and environment security
Duration depends on the size of the area, the number of rooms, and the sweep scope. A typical executive office takes 2-4 hours; a large boardroom can take 4-8 hours. Once scope is set, we build a detailed work plan and share the estimated duration.
We analyze unauthorized RF emissions, wireless device and emission risks, elements posing hidden camera/microphone/recorder risk, meeting security weaknesses, and room layout risks. Every finding is reported by risk level.
No. Penetration testing examines vulnerabilities at the system and application layer. TSCM assesses technical surveillance risks in the physical environment and the RF spectrum. Both matter for corporate security — they simply work at different layers.
It delivers the most value for holdings, manufacturing and R&D centers, finance and insurance institutions, healthcare organizations, law and consulting firms, and organizations running tender processes. It is critical wherever trade secrets and know-how live.
It depends on risk level. For high-risk areas we recommend periodic sweeps every 3-6 months. Sweeps can also run before critical meetings, after new hires, or whenever suspicion arises. Each organization gets a tailored sweep plan.
The full TSCM report is delivered within 3-5 business days after fieldwork ends. In urgent cases, preliminary findings can be shared the same day. The report covers the executive summary, technical findings, risk analysis, and action plan.
