This also provides secure access to the private network data by the users on the Virtual network. Such networks are quite efficient and useful for organizations and their users in maintaining privacy in the transactions and details of the organization. This would also make sure no sensitive data is accessed by any unauthorized user or outsider.
Some common types of Virtual Private Network are Site to site VPNs (connects two or more LANs), Remote access VPNs that can be for personal (individual) or corporate access. While corporate VPN allows connection to respective company’s network through a remote device, Personal VPN allows users anonymous surfs, secure shopping and transactions and privacy.
