Product Overview
The Cisco ASA 5505 is a full-featured firewall for small business, branch, and enterprise teleworker environments. It delivers high-performance firewall, SSL and IPsec VPN, and rich networking services in a modular, immediately operational appliance. Using the integrated graphical Cisco Adaptive Security Device Manager (ASDM), the Cisco ASA 5505 can be rapidly deployed and easily managed, helping businesses reduce operational costs. It features a flexible 8-port 10/100 Fast Ethernet switch whose ports can be dynamically grouped to create up to three separate VLANs for home, business, and Internet traffic for improved network segmentation and security.
The Cisco ASA 5505 provides two Power over Ethernet (PoE) ports, simplifying the deployment of Cisco IP phones with highly secure zero-touch voice over IP (VoIP) capabilities and the deployment of external wireless access points for extended network mobility. A high-performance intrusion prevention and worm mitigation service is available with the addition of the Advanced Inspection and Prevention Security Services Card (AIP SSC). Multiple USB ports can be used to implement additional services and capabilities, as needed.
As your business needs grow, you can install a Security Plus upgrade license, The Cisco ASA 5505 can then scale to support a higher site to site VPN connection capacity of 25 IPsec VPNconnections, add full DMZ support, and integrate into switched network environments through VLAN trunking support. This upgrade license improves business continuity by helping to enable support for redundant ISP connections and stateless active/standby high-availability services.
Businesses can also extend the Cisco ASA 5505’s VPN service by enabling the Cisco AnyConnect client and clientless VPN remote access to support various mobile workers and business partners. Cisco secure remote access solution deployments can scale to serve up to 25 Cisco AnyConnect or clientless VPN concurrent users on each Cisco ASA 5505. Licenses for AnyConnect are purchased separately from the ASA based on feature tier (Plus/Apex) unique/authorized user count and term. The Apex tier also supports clientless SSL VPN connectivity. Additional information can be found in the AnyConnect ordering guide.[link removed by ].
This combination of market-leading security and VPN services, advanced networking features, flexible remote management capabilities, and future extensibility makes the Cisco ASA 5505 an excellent choice for businesses requiring a best-in-class small business, branch, or enterprise teleworker security solution.

1Maximum throughput measured with UDP traffic under ideal conditions.2Firewall traffic that does not go through the IPS service can have higher throughput.3VPN throughput and maximum sessions depend on the ASA device configuration and VPN traffic patterns, including average packet size. These elements should be taken into consideration as part of your capacity planning. Throughput represents the maximum possible IPsec throughput. Maximum users may be further limited by your throughput requirements.4AnyConnect licenses required. See the AnyConnect Ordering Guide for details. Maximum users may be further limited by your throughput requirements.
