ZoneAlarm may be the most popular free firewall on the planet – arguably, this is the product that made everyone conscious of the need for firewall protection. The most recent release supports Vista (Download ZoneAlarm for Vista here.).
It's easy to use and its method of configuring outbound protection is particularly useful.
Whenever a program tries to make an outbound internet connection, ZoneAlarm announces it with a pop-up alert. You can then permit or disallow the connection, on a one-time basis or permanently.
Comodo Firewall Pro
ZoneAlarm is popular, but that doesn't make it the best free firewall you can find. One formidable rival is Comodo Firewall Pro, which independent testing site Matousec rated as the top firewall.
Matousec found that Comodo offered the highest level of 'antileak protection', one measure of a firewall's effectiveness.
