The Cisco ASA 5580-20 and 5580-40 Adaptive Security Appliances deliver multigigabit security services for large enterprise, data center, and service-provider networks in a robust, 4-rack-unit form factor. The Cisco ASA 5580 accommodates high-density copper and optical interfaces with scalability from Fast Ethernet to 10 Gigabit Ethernet, enabling unparalleled security and deployment flexibility. Cisco ASA 5580 Adaptive Security Appliances include six interface card expansion slots with support for up to 24 Gigabit Ethernet interfaces or up to twelve 10 Gigabit Ethernet interfaces that simplify provisioning and enable campus segmentation. Furthermore, this high-density design enables security virtualization while retaining physical segmentation desired in managed security and infrastructure consolidation applications.

The Cisco ASA 5580 Series is offered at two performance levels: the Cisco ASA 5580-20 with 5 Gbps of real-world firewall performance, and the high-end Cisco ASA 5580-40 with 10 Gbps of real-world firewall performance. Their multicore, multiprocessor architecture delivers radical scalability for the most demanding network security and VPN concentration applications. Real-time applications can be transparently secured thanks to the extremely low latency, high session concurrency, and connection setup rates.

Businesses can scale their SSL and IPsec VPN capacity to support a larger number of mobile workers, remote sites, and business partners. Up to 10,000 AnyConnect and/or clientless VPN peers can be supported on each Cisco ASA 5580 by installing an Essential or a Premium AnyConnect VPN license; 10,000 IPsec VPN peers are supported on the base platform. Cisco ASA 5580 Adaptive Security Appliances can also be clustered to improve reliability and scalability, with support for up to 100,000 AnyConnect and/or clientless or IPsec remote-access clients when deploying 10 appliances in a cluster. For business continuity and event planning, the ASA 5580 can also benefit from the Cisco VPN FLEX licenses, which enable administrators to react to or plan for short-term bursts of concurrent Premium VPN remote-access users, for up to a 2-month period.

Additional features, including security virtualization through the use of security contexts and VLANs, increase service velocity while reducing operational and administrative overhead.
