A secure and private communication connection between two or more devices across a public network, such the internet, is provided by VPN (Virtual Private Network) technology. When data is sent between devices, VPNs utilize encryption and tunneling protocols to safeguard its confidentiality, integrity, and authenticity. Remote users, branch offices, or devices can be linked to a main network via VPNs, giving them access to resources just as they were physically present there.

In conclusion, VPN and IPsec are complementary technologies that offer private and secure communication across public networks. IPsec is a set of protocols used to protect IP communications, whereas VPN is a technology that establishes a private network within a public network. For the secrecy, integrity, and validity of data transported across the internet and other public networks, VPNs and IPsecs are both necessary.
