WebIKE, also called ISAKMP, is the negotiation protocol that lets two hosts agree on how to build an IPsec security association. ISAKMP separates negotiation into two phases: Phase 1 and Phase 2. Phase 1 creates the first tunnel, which protects la ter ISAKMP negotiation messages. Phase 2 creates the tunnel that protects data.

WebIKEv1 specifies two significant negotiation phases for IKE and IPsec SA establishment: Phase 1: Establishes a bidirectional ISAKMP SA between two IKE peers. Once established, any peer can start phase 2 negotiations. Phase 2: Establishes unidirectional IPsec Security Associations (SAs) using the ISAKMP SA established in phase 1.
