Cisco FWSM

The Firewall Services Module (FWSM) is a firewall module integrated by Cisco into its Komodo blade on Catalyst 6500 Switches and 7600 Series Routers.

Installed inside a Cisco Catalyst 6500 Series Switch or Cisco 7600 Internet Router, the FWSM allows any VLAN on the switch to be passed through to the device to operate as a firewall port and integrates firewall security inside the network infrastructure.
