Espionage- and eavesdropping-secure facilities

Advanced espionage- and eavesdropping-secure facilities for authorities, defense, police and international institutions that meet the highest security and eavesdropping protection requirements.

Espionage- and eavesdropping-secure facilities

At IAC Acoustics, we specialize in the design, construction, and delivery of high-security solutions that protect against electronic eavesdropping (SIGINT), radio frequency scanning (RF), electromagnetic signal compromise (TEMPEST), and acoustic leaks. Our solutions are suitable for:

• Defense and military units
• Intelligence services and police
• Government and security authorities
• NATO and EU institutions

We build stationary, mobile, and modular espionage- and eavesdropping-secure facilities according to the strictest national and international standards, with a particular focus on EU, NATO, Denmark, Norway, and Sweden’s classification of secure areas.

EU Classified Information (EUCI) – EU Security Levels

The EU regulates secure areas under the EUCI system, classifying information and the facilities that protect them:

• EU RESTRICTED – Basic security level with fundamental access control.
• EU CONFIDENTIAL – Requires physical security, access control, and surveillance.
• EU SECRET – Stricter access rules, enhanced surveillance, and protection against electronic eavesdropping.
• EU TOP SECRET – The highest security level, featuring fully shielded rooms, signal protection, and advanced access control.

All EU-classified areas must comply with the EU Security Policy Framework.

NATO’s Classification of Secure Areas

NATO follows a similar classification system, where the highest levels require total protection against signal and electromagnetic eavesdropping:

• NATO RESTRICTED
• NATO CONFIDENTIAL
• NATO SECRET
• COSMIC TOP SECRET (equivalent to EU TOP SECRET)

Facilities handling NATO-classified information must comply with NATO’s security policy (C-M(2002)49).

Nordic Countries

In the Nordic countries, facilities handling classified information must comply with both NATO and EU security standards, while also following national regulations: Denmark under the Center for Cyber Security (CFCS), Norway under the National Security Authority (NSM) and the Security Act (Sikkerhetsloven), Sweden under the Security Protection Act (Säkerhetsskyddslagen), the Armed Forces and MSB’s guidelines, and Finland under the Security Clearance Act and guidance from SUPO and the Ministry of Defence.

SCIF & SAPF – When compromise is not an option

We also have expertise in designing and installing Sensitive Compartmented Information Facilities (SCIF) and Special Access Program Facilities (SAPF). These facilities safeguard classified communication and operations against both electronic surveillance and physical intrusion.

Our solutions include:

• Fixed facilities – Permanently integrated into existing buildings.
• Mobile units – Container-based security solutions for missions.
• Modular installations – Tailor-made solutions for specific security needs.

Notably, IAC Acoustics' SCIF Doors are approved by the U.S. authorities for installation in SCIF/SAPF and other secured facilities designed in accordance with C Tech Spec – for ICD/ICS 705 and JAFAN 6/9.

These doors can be equipped with GAS-approved S&G 2740B and Kaba Mas X-10 locks.

Requirements for Espionage-secure facilities

To ensure an area meets the highest security and eavesdropping protection standards, the following elements must be in place:

• Physical security – Secure walls, doors, and windows to prevent unauthorized access.
• Access control – Biometric identification, authorized access logs.
• Surveillance – CCTV, motion sensors, and security logging.
• Electronic eavesdropping protection – Shielding against SIGINT, TEMPEST certification.
• Communication security – Encrypted lines, signal management, RF shielding.

To deliver total security, we integrate a wide range of highly specialized products into our solutions:

• High-security doors & wall panels – Prevent both physical intrusion and signal leakage.
• Ventilation panels – Allow airflow without risking acoustic leaks.
• Electrical filters & EMI/RF shielding – Neutralize signal manipulation and electromagnetic leakage.
• Acoustic security – Compliant with NATO and EU soundproofing standards.
• Faraday cages & shielded rooms – Complete protection against electronic eavesdropping and signal emissions.

Our solutions safeguard confidential operations against the latest threats from hostile actors, SIGINT surveillance, and advanced eavesdropping techniques.

IAC Acoustics' solutions can comply with the strictest requirements, including:
