The Cisco ASA 5550 Adaptive Security Appliance scales with businesses as their network security requirements grow, delivering exceptional investment protection and services scalability. Businesses can scale their SSL and IPsec VPN capacity to support a larger number of mobile workers, remote sites, and business partners. Up to 5000 AnyConnect and/or clientless VPN peers can be supported on each Cisco ASA 5550 by installing an Essential or a Premium AnyConnect VPN license; 5000 IPsec VPN peers are supported on the base platform. VPN capacity and resiliency can also be increased by taking advantage of the Cisco ASA 5550’s integrated VPN clustering and load-balancing capabilities. The Cisco ASA 5550 supports up to 10 appliances in a cluster, supporting a maximum of 50,000 AnyConnect and/or clientless VPN peers or 50,000 IPsec VPN peers per cluster. For business continuity and event planning, the ASA 5550 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.
Using the optional security context capabilities of the Cisco ASA 5550 Adaptive Security Appliance, businesses can deploy up to 100 virtual firewalls within an appliance to enable compartmentalized control of security policies on a per-department or per-customer basis, and deliver reduced overall management and support costs.
