VPN Basics: Internet Protocol Security (IPSec) Internet Protocol Security (IPSec) is an Internet Engineering Task Force (IETF) standard suite of protocols that provides data authentication, integrity, and confidentiality when data is transferred between communication points across IP networks. IPSec provides data security at the IP packet level. IPsec | InfoSec News All IPsec VPN configurations require at least two items: (1) the Internet Security Association and Key Management Protocol (ISAKMP) or Internet Key Exchange (IKE) policy; and (2) the IPsec policy. If the cryptography on either of these policies is configured to allow obsolete cryptographic algorithms, the entire VPN is at risk and data Remote Secure Access VPN | Check Point Software

When properly configured, an IPSEC VPN provides multiple layers of security that ensure the security mode and integrity of the data that is being transmitted through the encrypted tunnel. This way an organization can feel confident that the data has not been intercepted and altered in transit and that they can rely on what they are seeing.

Below is a list of the Cryptographic algorithms used in IPSec Authenticity & Integrity Protection HMAC-SHA1/SHA2 Confidentiality 3DES-CBC it can also use AES-CBC and AES-GCM it's worth noting that AES-GCM will also do authentication, so that could be a reason for choosing it.
