GSMK is a leader in mobile voice and message security. Located in Berlin, Germany, the company develops, produces and markets the first mobile, satellite and desktop phones that provide strong end-to-end voice encryption with full source code published for review.

GSMK CryptoPhones were the first products to take advantage of the fact that the

CPU performance of portable consumer devices, like mobile phones and PDAs, is now sufficient for strong real-time voice encryption. The processing power that is available today in every pocket now makes it possible to effectively counter rampant telecommunications surveillance and targeted attacks on your sensitive information.

They envision a day when strong, verifiable and trustworthy voice encryption in all mobile devices will be commonplace, just like strong encryption is in Internet routers today. Recent technological advances now finally allow every one of us to regain some of the privacy they lost. Widespread, uncontrolled wiretapping and privacy violations are currently threatening the business environment, civil liberties, and the very future of democratic societies.

There seems to be no realistic way to stem by political process alone the current flood of intrusive communication surveillance, industrial espionage, and the risk for democratic institutions that comes with it. With the advent of GSMK CryptoPhones, strong cryptographic protection of confidential voice calls and messages has finally become available to a wide range of individuals, corporations, and institutions.

GSMK CryptoPhones mean voice and message encryption you can trust.

From its very first secure mobile phone, the first product world-wide to encrypt mobile telephone calls in real time by taking advantage of the CPU performance of modern mobile devices, GSMK has created groundbreaking products that have defined the industry.

- Mobile device security: GSMK has pioneered the development of hardened mobile devices and operating systems that offer true 360-degree protection not only against attacks on communication links, but also against attack on the device itself. GSMK’s history of serving very demanding clients that can not afford the security of their communications to be compromised – be they governments, international institutions, or private clients – has made the company very familiar and uniquely qualified to deal with an organization’s requirements to secure large fleets of mobile devices.
