Cisco IOS Firewall helps ensure your network's availability and the security of your company's resources by protecting the network infrastructure against network- and application-layer attacks, viruses, and worms. It protects unified communications by guarding Session Initiation Protocol (SIP) endpoints and call-control resources. Cisco IOS Firewall is a stateful firewall solution, certified by Common Criteria (EAL4).
Suitable for branch offices, small to medium business environments, or managed services, Cisco IOS Firewall effectively controls application traffic on the network. A fundamental part of the Cisco Integrated Threat Control framework, it works with other Cisco IOS security features, including Cisco IOS Intrusion Prevention System (IPS), IOS Content Filtering, and IOS Network Address Translation (NAT), to create a completely integrated branch-office perimeter security solution.
