The coverage, resilience and flexibility provided by satellite communications make it the most suitable technology for security communications.

Satellites operators understand the communications requirements of military and civil Government users:

Mobility: Security activities are increasingly about small groups or units that need to move quickly – "mobile expeditionary forces" – for example to get to an airport to deploy rapidly to a remote location, whether in support of UN Peace Keeping Operations or more active military operations, such as Afghanistan or Iraq.

A total solution: Very Small Aperture Terminals (VSAT) that operate in higher frequency bands (Ku/Ka) provide greater bandwidth and capacity, but are generally more permanent installations in a deployed command post. L-Band mobile satellite services deliver voice and IP-based data services through light-weight, portable terminals for mobile and remote groups

All-weather: Satellite services provided over L-Band do not suffer from attenuation of their satellite signals by rain, snow, or other water-based weather conditions, offering more resilient and reliable satellite services for essential communications.

Interoperability: Fixed and some mobile satellite service operators provide satellite communications over an IP architecture, enabling military forces, civilian security services and aid/NGO first-responder agencies to have access to voice communications and all normal IP-based services and applications, such as email, VPN, internet browser, etc.

Information assurance: Users can employ a range of cryptographic hardware and software-based information security solutions to ensure the privacy and integrity of their voice and data communications
