So as a result of Cisco getting more and more into the small business world, they have finally decided to position a small business firewall in the market for the smallest of small businesses. The Cisco SA 500 series of security appliances. This is from the Cisco Small Business Pro line.
The Cisco SA 500 series comes in a variety of models, the SA 520, 520W and 540. The 520W is particularly nice because it provides built-in wireless functionality as well. The 540 is basically the version that supports the most throughput and is the higher end version of the bunch.
From using the SA 520, it is apparent from the start that it is meant to be user friendly. The entire device is configured via the GUI and there is no command line to worry aobut. If you just need a small appliance to drop into a very small business for basic Internet access and firewalling capability, this is a great solution. On top of all that it has VPN and VLAN support so you can do some business-like configuration of the device instead of just throwing in a home based router/firewall.
