About ZoneAlarm

ZoneAlarm is a well-regarded personal firewall product offered by Zone Labs. Like most firewall software, it alerts the user to any hacking attempts on your computer. Significantly, it also alerts on outbound attempts, when an unrecognized program seeks to access the Internet. The firewall that Microsoft includes in Windows XP lacks outbound protection, highlighting the need for firewall protection beyond what it offers. In ZoneAlarm, access requested by any program can be allowed or denied. The user can easily specify preferred inbound and outbound access privileges for various programs either as each seeks access for the first time, or at any later time. The free version of ZoneAlarm is generally recognized as a fine firewall, and is a very popular download. Zonelab's business model is to continue to improve the free basic model while offering upgrades with more features for a price.
