SourceCheck Point Software today released ZoneAlarm Internet Security Suite 7.1, a Vista-compatible version of its flagship security suite. Vista-compatible versions of ZoneAlarm Antivirus and the popular free ZoneAlarm Firewall are also available.
Past versions of ZoneAlarm's products have relied on Microsoft's TDI (Transport Device Interface) to track network behavior. Windows Vista retains support for TDI, but introduces the new Windows Filtering Platform (WFP). While porting to Vista using TDI would have been easier, Check Point chose to support WFP for this Vista-compatible version. When installed on Windows 2000 and XP, however, version 7.1 will still use TDI.
According to the Zonealarm forum, the Vista compatible versions go live today (June 14, 2007).
