The Cisco VPN Internal Service Module (VPN ISM) is a module for the Cisco Integrated Services Routers Generation 2 (ISR G2) that provides the capability to considerably increase performance for VPN encrypted traffic. The module has a multicore processor that operates independently of the host router resources, helping ensure maximum concurrent encrypted application performance while maintaining competitive performance for other types of traffic. The Cisco VPN ISM supports the latest versions of cryptography standards, including stronger National Security Agency (NSA) regulated cryptographic algorithms such as Suite B Cryptography. Service Module offers better usage with maximum efficiency and convenience Service Module with optical network application/usage for maximum dependability and convenience
