Get information about Firewall Products based on surveys of vendors. You can also choose to compare product features side-by-side, and follow links to contact vendors. Note that the surveys are currently sadly out-of-date, as my support for this project was cut off in 2003. I've decided to revive the surveys, and add questions about IPv6 support in firewalls, so look for updated surveys in the near future. Also look for new, short articles about how firewalls work, why firewalls don't protect you from current security threats, and more. Firewalls are still an essential part of network security, whether you have one Internet-connected system via cable or your neighbor's wireless, or manage a large network for a business. The search tool permits comparison on a feature-by-feature basis by selecting the Compare button, and picking out the features you are most interested in. You can ignore features you don't care about by leaving those questions blank, as well increasing the weighting of those features that are most important to you. The resulting list of products shows the relative ranking for products based on your selection criteria. The Firewall Archives include older papers by firewall experts.
