National governments as well as international organizations have a wide range of missions and tasks to fulfil in an equally wide range of organizational and legal frameworks.

Serving the mobile security needs of institutional clients in over 50 countries worldwide, we know that no two organizations are alike, and that each individual mission requires great attention to detail to ensure that the COMSEC infrastructure that is to support this mission is up to the task.
Governments need to run large, complex communication networks that must provide reliable platforms for classified information.
A Ministry of Foreign Affairs, for example, must rely on a global transnational network to transport sensitive information between the Ministry at home and embassies and missions around the world. Many of these will be capable of communicating over multiple communication channels including satellite. In addition, in each country, the local embassy needs to be able to communicate securely with the ambassador’s residence, travelling attachés, and other staff members – and they need to be able to consult with officials at home using a secure line. To meet these needs, GSMK can provide a comprehensive secure communications system that is customized to a client’s individual requirements, can be easily scaled when needed, and that can adapt to changing requirements over time.
