Mobile devices and electronic communication of governments and NGOs, especially in the context of international diplomatic, military and human rights missions, are permanently subject to surveillance, recording, and attacks against data at rest as well as data in transit using advanced spyware.

When faced with such challenges, national governments and high-profile international organizations alike rely on GSMK CryptoPhones to defend themselves against cyber attacks. Field-proven over the course of two decades, GSMK CryptoPhones have earned a stellar reputation for security and reliability - whether operated at home or abroad, whether in the world’s largest cities or in remote areas with poor network coverage and performance.

GSMK covers the entire process from planning to deployment and operation of your individual secure communications infrastructure. GSMK’s lifecycle management services protect your investment and ensure continuous updates and upgrades as your needs grow. The company and its authorized distribution partners are there for you to ensure that you can maximize the lifetime of your existing GSMK CryptoPhone system, and that you can continuously upgrade it to keep up with changing requirements and the growth of your secure communications network.
