The invention relates to the field of communications, and discloses a web service mapping method and a system of a security agent in a virtual private network (VPN). Web response analysis and rewriting processes are simplified, achieving is easy, and stability and efficiency are high. In the web service mapping method and the system of the security agent in the VPN, the mapping relation of a domain name or a port which supplies web services and security agents is preset by the security agent in the VPN, wherein different web services correspond to different domain names or different ports.
