Where an organisation has multiple sites which are each connected to the Internet, and wishes to join these into a single large network, a Virtual Private Network (VPN) can be used. A VPN is created by setting up encrypted "tunnels" across the Internet between the sites. For this each site requires a Firewall.

Clearstream manages hundreds of VPN networks in the UK and internationally using SonicWALL VPN UTM appliances. SonicWALL UTM appliances are compatible with many other VPN devices supporting industry standard encryption standards. Customers with CISCO, Checkpoint, Nortel Contivity and many other devices can incorprate SonicWALL seamlessly into their network designs.






Clearstream and SonicWALL offer a range of VPN appliances from 20Mbps throughput to Gigabit throughput with full hardware redundancy, to satisfy the largest applications.
