What the experts say about us:

“Since the BYOD trend transformed mobile computing and communications, organizations relied on either luck, or software based solutions to secure their voice and SMS communications on smart phones. WHITE NOISE raises the bar and sets the new standard for secure mobile communications with a Swiss made secure element (SE), separate from the smart phone supply chain that encrypts and decrypts communications on the chip itself. Even more impressive is the integration of the SE chip into a Bluetooth headset commonly used in office environments which helps to eliminate the friction of increasing communications security in office settings.”
