The Integrated Services Module (ISM) for Cisco 7100 series VPN routers provides high-performance, hardware-assisted tunneling and encryption services suitable for virtual private network (VPN) remote access and site-to-site intranet and extranet applications. As an integral component of the Cisco VPN solution, the ISM provides platform scalability and security while working seamlessly with all services necessary for successful VPN deployments - -security, quality of service (QoS), firewall and intrusion detection, service-level validation, and management. This integration, combined with ISM support for the broad set of WAN media and services offered by the Cisco 7100 series router, ensures the smooth integration of VPN technology into any enterprise or service provider network.
