VPN or virtual private network creates secure network connection using the internet enabling organisations to have an internal network. It is also quite useful in connecting the various branches of the offices located in different locations to the main office using a cohesive network. VPNs can connect multiple networks together securely; most organisations use VPNs to share servers and other networked resources among multiple offices. Moreover, it is useful in providing online privacy to the users especially while connecting to public or untrusted network such as Wi-Fi in a coffee shop. The increasing threats to the online users are leading to the requirement for secure services such as VPN. VPN is widely used for its features; it is possible to set up VPN using both Windows 7 and also Windows 8 while following the few steps of the simple set up process.VPN is considered most useful for corporate communications as it facilitates exchange of confidential voice messages, video or data. VPN service consists of a web of computers linked together to share files and other resources. The traffic over any VPN is encrypted to ensure the privacy of data; all the data is encrypted on sending and decrypted only on receiving. Such process prevents the disclosure of data as only authenticated users can access the data using passwords. The relative speed, ease and convenience are leading to the wide application of VPN in organisations. Organisations can adjust the number of sites in the VPN according to changing requirements. Large organisations, educational institutions and government agencies use VPN service. VPN is known for its connectivity as it is widely used by remote users to access private networks securely. Besides it basic functions, VPN is very helpful in connecting users to their home or offices while they are travelling or located in remote areas.
