New to VPNs?

 

 

VPN, or Virtual Private Network, is a group of two or more computer systems, typically connected to a private network, that communicates securely over a public network (typically the Internet). VPNs may exist between an individual machine and a private network (client-to-server or remote access) or a remote LAN and a private network (site-to-site).

Site to site VPNs involve the use of dedicated VPN hardware at each remote site. They generally provide more robust and lower latency connections, and are setup in an “always on” mode. Typically TenacIT provides these to customers, as they provide the best performance, click here for our VPN services

A VPN connection extends the boundaries of the physical network. Computers that gain access to a VPN can potentially access all the resources of the private network as if they were physically connected to it. This allows for workers, consultants, external vendors and offshore support to connect to the corporate network from any spot on earth, and perform their job remotely. The number of concurrent VPN connections is only limited by the public network bandwidth and the performance capabilities of the VPN server/appliance.

VPNs provide encryption and additional security measures to ensure that only authorized users have access to the network and its data. Traffic is encrypted in both directions while it travels the public network.

Since VPN is a secure method for allowing remote users access to a private network (and in most cases – cheaper and faster than old dial-up connections), VPNs are usually used in cases where remote users require secure access to network resources that could not be accessed in any other way
