The cisco asa 5505 adaptive security appliance is a next-generation, full-featured security appliance for small business, branch office, and enterprise teleworker environments that delivers high-performance firewall, ssl and IPsec vpn, and rich networking services in a modular, "plug-and-play" appliance. Using the integrated web-based cisco adaptive security device manager, the cisco asa 5505 can be rapidly deployed and easily managed, enabling businesses to minimize operations costs. The cisco asa 5505 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, enabling simplified deployment of cisco ip phones with zero-touch secure voice over ip (voip) capabilities, and deployment of external wireless access points for extended network mobility. The cisco asa 5505 also provides significant expandability and investment protection through its modular design, similar to the rest of the cisco asa 5500 series, offering both an external expansion slot and multiple usb ports that enable the addition of services in the future.
