We protect against wiretapping, spying and industrial espionage

Eavesdropping and bugging protection

Companies, authorities, and individuals are increasingly being targeted by a constantly growing number of complex threats aimed at espionage of confidential data and information.

In addition to the worldwide booming cybercrime, the traditional eavesdropping device ("bug") continues to thrive and is being used in increasingly sophisticated variations at more affordable prices. According to a study by the "Bitkom" association, the costs incurred annually due to espionage, industrial and economic espionage, and malicious employees amount to over 50 billion euros.

Measures for counterespionage, cyber counterespionage, detection of bugs and eavesdropping devices, and technical eavesdropping protection are becoming increasingly necessary.

To protect our customers from these attacks, our TÜV-certified counterespionage team only works with the most advanced defense technologies.

TSCM // Eavesdropping protection for businesses

We protect confidential information for your company and effectively fend off targeted attacks.

To achieve this, we conduct thorough inspections of your office and business premises to detect hidden bugs (bug detection), eavesdropping devices, transmitters, and all types of cameras.

We also examine your telephones (VoIP, analog, or ISDN) and your IT infrastructure (routers, LAN, WLAN) for manipulations or attacks, and conduct searches for bugs and eavesdropping devices.

With our conference and meeting protection service, we offer professional eavesdropping protection and countermeasures for your conferences, meetings, and gatherings worldwide.


Eavesdropping protection for private individuals

Do you feel like you're being watched? Do other people know things about you that they shouldn't? Eavesdropping attacks with bugs and listening devices on private individuals occur much more frequently than expected.

Often, it's neighbors or ex-partners who equip houses or apartments with bugs, surveillance cameras, or hidden microphones or engage in surveillance.

With our private eavesdropping protection service, we conduct a thorough examination of your private living spaces for bugs and eavesdropping devices. We check your mobile phone and IT devices (router, notebook, WLAN) for spy apps and search for hidden listening devices while detecting bugs.

Regain a sense of security in your living spaces and bring the perpetrators to justice.

Technical Surveillance Countermeasures (TSCM) for Businesses

To ensure that confidential information truly remains confidential

The risk of being eavesdropped on and spied upon affects almost everyone nowadays.

Often, it is domestic and foreign competitors, commercial surveillance services, or foreign governments trying to gain access to your confidential information and company know-how.

Passive countermeasures, also known as passive eavesdropping protection, refer to preventive measures against unwanted eavesdropping and surveillance techniques.

Through structural and technical eavesdropping protection measures, we make eavesdropping attacks and espionage attempts virtually impossible
