The Cisco PIX VPN Accelerator Card+ (VAC+) delivers high-performance, hardware-accelerated IP Security (IPSec) VPN, support for state-of-the-art international cryptographic standards, and highly scalable VPN tunnel aggregation in a solution that comes integrated with, or as an upgrade for, most models of the market-leading Cisco PIX Security Appliance series. Ranging from solutions for small to midsize businesses (SMBs) to large enterprises and service providers, the Cisco PIX Security Appliance series offers extensible platforms that provide robust, enterprise-class integrated network security services and solid investment protection. The Cisco PIX VAC+ takes full advantage of this extensibility and maximizes platform investment protection by offloading computationally intensive VPN cryptographic functions. This enables Cisco PIX Security Appliances to deliver higher-performance stateful inspection firewall services, advanced application and protocol inspection, inline intrusion protection, and robust multimedia and voice security services.
