Cell Phone Spying: Is Your Life Being Monitored?!

Eavesdroppers, governmental bodies, and hackers are all out there - but you can prevent them from accessing your private life. Our voice encryption software will help you to protect all your phone calls from interception.

Click on the "Play" button below to listen to a conversation intercepted by a GSM network operator between two cell phones (both were using Secure Voice GSM software).

(Depending on your Internet connection speed the load time before the record starts to play will vary. If the record does not start, you may download it here).

Secure Voice GSM: User Interface

Secure Voice GSM has intuitive interface, works reliably in the background and uses very little system resources. Some software screenshots can be seen below.

2. By pressing the dial button the Secure Voice GSM software starts to establish a secure connection with another cell phone (installed Secure Voice GSM is required).

3. Once connected, the authentication process starts.

4. Once authentication is successful, the key exchanging process begins.
