Secure Communication with Mobile Devices
Geozone SecureTalk is a mobile communication solution that combines 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, GeozoneSecureTalk protects your operations by keeping your communication 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 that can be 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 to facilitate very flexible deployment options and cover different end user needs and security levels.
GeozoneSecureTalk provides a cost-effective solution that delivers high voice quality over multiple IP networks such as EDGE, UMTS, WiFi or Satellite. In addition, portable and tactical networks can be 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. On request, we can customize the security parameters and algorithms embedded in the product.
