Comprehensive protection and prevention against eavesdropping – professional solutions for your security.



📋 Solution Proposal: Active Information Protection and Prevention

Dear Customer,
In today's competitive environment, information, strategic plans and business secrets are the most valuable assets of your company. However, with the advent of digital technologies, 5G networks and artificial intelligence, the risk of industrial espionage has increased dramatically. According to global security analyses for 2026, the market for eavesdropping technology is experiencing massive growth, with up to 39% of demand for protection now coming from large enterprises and corporations actively protecting their data.

Traditional one-time inspections (so-called "bug sweeps") are no longer sufficient for modern threats. We offer you a comprehensive, integrated TSCM (Technical Surveillance Counter-Measures) system that combines cutting-edge radio frequency analysis, physical security and continuous real-time monitoring.

🔎 I. What does a professional TSCM system include

Professional protection is not about one miracle device from an e-shop. It is a methodological and technological ecosystem divided into key components:

1. Hardware and technical infrastructure

  • Broadband RF analyzers (SDR) – Continuously scan the radio spectrum (from 9 kHz to tens of GHz). Detect modern transmissions including 5G, Wi-Fi 6E/7 and satellite communications.
  • Non-Linear Junction Detectors (NLJD) – Search for semiconductor components. Can locate a microphone or camera hidden in a wall or furniture, even when the device is completely turned off or discharged.
  • Thermal imaging and physical inspection – Professional thermal cameras reveal microscopic heat traces emitted by working electronics. Physical inspection includes disassembly of sockets, ceilings and inspection of interior items.
  • Cable analysis (VLF/LF) – Inspection of power distribution, Ethernet networks and air conditioning, which attackers often abuse for covert data transmission or power supply.

2. Setting security priorities

  • Critical spaces – Meeting rooms, top management offices, spaces for strategic mergers and acquisitions (M&A).
  • Data infrastructure – Server rooms, network nodes, telephone exchanges.
  • Mobile component – Protection of management vehicles and securing communication on business trips.

🛠 II. Implementation options: Two pillars of protection

A. Tactical one-time inspection (Sweeps)

In-depth technical and physical inspection of the space carried out by our expert team before an important meeting or at regular intervals (quarterly/semi-annually).

B. Continuous active protection (IPMS)

  • Creation of digital fingerprint (Baseline) – The system learns the normal radio profile of your office (official Wi-Fi, Bluetooth keyboards).
  • Anomaly detection and AI analysis – Approximately 41% of modern TSCM solutions today use automated threat detection using artificial intelligence. If an unknown signal activates in the room, the system immediately raises an alarm.
  • Precise localization – Thanks to advanced triangulation, the IPMS system can pinpoint the position of a bug in space with an accuracy of 1 to 3 meters.
  • Intelligent acoustic masking – Acoustic transducers generate white noise directly on windows, eliminating the threat of laser microphones that detect glass vibrations from outside. Special ceiling sound-masking systems cover human speech for possible dictaphones, while you hear normally at the table.

📊 III. Comparison of approaches (Pros and Cons)

To help you make the right decision, we provide a transparent overview of the advantages and disadvantages of each solution:

Security solution Benefits (PRO) Limitations (CON)
One-time Sweep (Tactical inspection)
  • Excellent detection of switched-off bugs thanks to NLJD.
  • Lower initial costs.
  • Detailed physical inspection.
  • Protects the space only at the moment of inspection.
  • The attacker can install a bug immediately after the technicians leave.
Continuous IPMS (Active protection 24/7)
  • Permanent protection 365 days a year.
  • Detects sophisticated attacks (recording during the day, sending data at night).
  • Immediate alarm and localization.
  • Higher initial investment in hardware.
  • Cannot detect devices that do not transmit (pure dictaphones).

💡 Statistical fact
According to recognized Western studies (e.g. Bastille Insights), the probability of detecting a sophisticated, irregularly transmitting bug using occasional one-time sweeps is less than 5%. With continuous monitoring (IPMS), this success rate rises to more than 98%.


⚠️ IV. Implementation pitfalls and limitations

As a professional partner, we deal with you openly. No system in the world provides 100% protection if other security components are neglected.

  • Human factor ("Internal enemy") – If a manager or employee deliberately takes information out, or records a meeting on their own smartphone in their pocket, technical means in the room will not prevent it.
  • Purely passive recording – Miniature dictaphones that store audio on an internal micro-SD card and do not transmit any radio signal. IPMS will not detect them. They can only be eliminated by a combination of acoustic noise and regular physical sweeps using NLJD.
  • Software compromise (Cyber-TSCM) – If the attacker does not attack the room, but directly infects your smartphone or laptop with spyware (e.g. abuse of Teams, Zoom platforms), physical protection of the space will not stop the leak. Communication security also requires cyber protection of end devices.
  • Legal restrictions in the EU – The deployment of active radio jammers (RF jammers) is illegal for civilian entities in Slovakia. Our company therefore strictly implements legal forms of protection – radio frequency shielding of spaces (Faraday cage) and acoustic masking, which are 100% safe and in accordance with the law.

📈 V. Proposed optimal procedure (Strategic recommendation)

Based on best international practice, we recommend a Hybrid protection model for medium and large enterprises that minimizes blind spots:

  1. Phase 1: Initial deep sweep (Tactical audit) – We will clean the premises of all historical, dormant or passive devices using NLJD, thermal imaging and physical inspection.
  2. Phase 2: Implementation of IPMS (Continuous shield) – We will deploy discreet sensors in cleaned key rooms (boardroom, CEO) for permanent monitoring of the radio spectrum and acoustic window masking.
  3. Phase 3: Regular audit and training – We will perform a control sweep once a year and retrain your staff in basic security hygiene (carrying smartphones to secret meetings, checking gift items).

➡️ VI. What will follow?

Every building is unique in its architecture and radio background. To prepare an accurate price calculation for you, we propose the following procedure:

  • Are you interested in a comprehensive hybrid model, or are you primarily looking for one-time security for a specific important meeting?
  • What is the approximate area (m²) or number of rooms you need to urgently protect?
  • Do you want to include scanning of company vehicles in the protection?

We look forward to possible cooperation in protecting your business. Our technologies are ready to ensure that your internal information remains truly yours alone.
