The Cisco Virtual Private Network modules (VPN modules) optimize the platforms for virtual private networks (VPNs). The Cisco VPN modules provide up to 10 times the performance over software-only encryption by offloading the encryption processing from the router central processing unit (CPU). Ideal for use in enterprise branch offices for connecting remote offices, mobile users, and partner extranets or service provider-managed services customer premises equipment (CPE), the Cisco VPN modules deliver a rich integrated package of routing, firewall, intrusion-detection, and VPN functions. As an integral component of Cisco VPN solutions, the Cisco VPN modules provide industry-standard encryption (IPSec), application-aware quality of service (QoS) and bandwidth management, together with robust perimeter security options.
