What is IPsec VPN?​

IPsec, Internet Protocol Security, is a protocol for the protection of Internet protocol (IP) transmission of data.VPN, on the other hand, is a dedicated network based on a public network that allows for secure data transfer.IPsec VPN, in combination with the advantages of both, can create a virtual private network in the public network to secure communications between different locations, including remote working, resource-sharing, etc.
