Secure communications with mobile devices


Geozone SecureTalk is a mobile communication solution combining multiple services such as telephony, instant messaging and SMS with sophisticated security mechanisms to protect your organization’s sensitive and classified information. Geozone SecureTalk transforms public networks and standard terminals into highly secure communication channels.

Targeted to government agencies, police and militaries, Geozone SecureTalk protects your operations by keeping communications secure and private. Members of your organization will be able to speak and exchange data with confidence, anywhere and anytime.

Traditional network based solutions used by governments and militaries are very expensive, complex to maintain and do not integrate well with standard wireless or wired communication devices, equipment and networks. The massive introduction of smartphone terminals and increasing mobility habits of public forces and government officials demand a more effective solution to protect classified and top-secret communications. A strong security suite, easily integrated into existing smartphones and networks is the aim behind Geozone SecureTalk. The solution offering also contains special hardened devices to meet the highest security requirements, facilitating very flexible deployment options covering different end user needs and security levels.

Geozone SecureTalk provides a cost-effective solution that delivers high voice quality over multiple IP networks such as EDGE, UMTS, WiFi or Satellite. Portable and tactical networks can be as well deployed on emergency or crisis missions and used with Geozone SecureTalk powered smartphones and computers securing all communications in the region and globally thanks to its double layer encryption architecture and its flexible deployment. We can customize on request the security parameters and algorithms embedded in the product.
