Techopedia Explains Internet Protocol Security VPN

IPsec primarily utilizes tunnel mode for creating VPN tunnels. IPsec provides an enhanced level of security on VPN connections by default by providing authentication, encryption and compression services at the network level of VPN. This is achieved through the encapsulated security payload (ESP), authentication header (AH) and IP payload compression (IPComp) protocol. For each outgoing IP packet it is encapsulated and secured using the IPsec packet.
