Virtual Private Networks
A VPN is a private network deployed over public facilities (such as the internet) and provides a similar level of security, quality of service and manageability to networks built entirely on dedicated, privately owned or leased facilities. VPNs are a new and exciting technology that can considerable reduce I.T. communication costs. At Imex we believe in dealing with the industry leading technology providers where the product and after sales support are of the highest level. Cisco hardware is responsible for 90% of internet traffic and are the world leader in firewall and VPN solutions.
