Manage Network Tunnel Groups

Tunnels and tunnel groups are core concepts in managing connections between your data centers and Cisco Secure Access.

Secure Access enables fast, reliable, and secure private network connections to your applications through IPsec (Internet Protocol Security) IKEv2 (Internet Key Exchange, version 2) tunnels.
Network devices that are capable of establishing IPsec tunnels forward traffic to one of the Secure Access data centers where the tunnel head end is located.
User devices can read, write, and update private resources by setting up virtual private networks (VPNs) or zero trust network access (ZTNA) connections to Secure Access through these IPsec tunnels.
A network tunnel group provides the framework for establishing tunnel redundancy and high availability. Connect tunnels to the hubs within a network tunnel group to securely control user access to the Internet and private resources.
