What kind of VPN does Cloud VPN employ between a VPC and a peered network?

Cloud VPN uses IPSec VPN technology to establish secure connections between a Virtual Private Cloud (VPC) and a peered network. IPSec (Internet Protocol Security) is a suite of protocols designed to ensure secure communication over IP networks by providing encryption and authentication.

Using IPSec allows for a robust level of security and is well-suited for site-to-site connections. This protocol is commonly used in enterprise environments where the need to encrypt traffic over the internet or untrusted networks is critical, making it the preferred choice for Cloud VPN in Google Cloud.

Aside from its strong encryption capabilities, IPSec also supports various configurations and can handle different types of traffic, making it versatile for various networking scenarios. This focus on security and flexibility is essential for organizations that require secure connections between their on-premises infrastructures or other cloud environments and their Google Cloud resources.
