A virtual private network (VPN) is a type of technology that uses a private channel to encapsulate and transmit data over the Internet. VPNs are typically encrypted to ensure that data security and privacy are not compromised by malicious third-party actors. VPNs can be used by private retail customers as well as large corporate environments to gain access to network resources and highly sensitive data that would otherwise be unavailable to the general public. VPNs are appropriately named because they provide virtual rather than physical access to a private network. They are classified into two types: remote access and site-to-site.
