The Double-Layered Defense
The link22 Shield isn’t just a container; it’s a sophisticated eavesdropping protection case that uses two distinct mechanisms to secure your environment:
- Acoustic Isolation: The box is constructed to physically block external microphones from picking up the nuances of human speech. By isolating the device from the room’s atmosphere, the “signal” available to a compromised phone is drastically reduced.
- Active Sound Masking: This is the “kill switch” for surveillance. Shield generates a layer of random noise. Unlike a steady hum that can be filtered out by modern AI audio tools, this randomized noise overlaps with speech frequencies, ensuring that even if a recording is made, the output is nothing but unintelligible static.
Integration Without Friction
For the energy sector, military, and government agencies, security only works if it is used. We designed Shield to require zero training. It functions as a natural part of the meeting ritual: phones go in, the lid seals magnetically, and the conversation begins.
By controlling the acoustic environment, Shield eliminates the most unpredictable variable in information security: the mobile phone.
