“A VPN is a generic term that describes any combination of technologies that can be used to secure a connection through an otherwise unsecured or untrusted network.”
Virtual Private Network services can impact your over all computing and network performance. It’s a communication network tunneled through another network, and dedicated for a specific network. One common application is secure communications through the public internet, but a VPN need not have explicit security features, such as an authentication or content encryption. They overlay other network(s) to provide a certain functionality that is meaningful to a user community.
The virtual private network (VPN) has opened up a wide range of possibilities for remote network access to files from almost any geographic location. Using VPN software, computer users can access the files on their home or office computer anywhere they can get a reliable Internet connection. Unfortunately, this easy access to files has also created a new threat in the form of data thieves, criminals who steal personal or sensitive information for personal gain or malicious use.
