The term Cisco IPsec is just a marketing ploy which basically means plain IPsec using ESP in tunnel mode without any additional encapsulation, and using the Internet Key Exchange protocol (IKE) to establish the tunnel. IKE provides several authentication options, preshared keys (PSK) or X.509 certificates combined with Extended Authentication (XAUTH) user authentication are the most common.
