![]() The ISA and the ISM provide hardware-accelerated support for multiple encryption functions: ![]() The ISA and the ISM off-load IPSec and MPPE processing from the main processor of the Cisco 7200 series or Cisco 7100 series router, thus freeing resources on the processor engines (that is, the network processor engine on the Cisco 7200 series, and the network processor on the Cisco 7100 series routers) for other tasks. Each provides high-performance, hardware-assisted tunneling and encryption services suitable for virtual private network (VPN) remote access, site-to-site intranet, and extranet applications, as well as platform scalability and security while working with all services necessary for successful VPN deployments-security, quality of service (QoS), firewall and intrusion detection, and service-level validation and management. The ISA is a single-width service adapter and the ISM is a single-width service module. Note The ISA and the ISM are the same board, but differ in their outside appearance.
