Free Zonealarm firewall available for download

Check Point Software Technologies launched a Windows Vista version of its flagship Zonealarm firewall and blamed the delay on a switch to the new operating system's application programming interfaces (API).

The Vista version of Zonealarm, a two-way firewall that will continue to be given away, is said to be the first from a major security vendor to apply Vista's Windows Filtering Platform (WFP), said Laura Yecies, the general manager of Check Point's consumer security line.

"This is a bit later than we would have liked," said Yecies, noting the four-month lag between Vista's retail release and Zonealarm's appearance. "We underestimated the schedule impact of WFP. But long term, WFP will give us more support and more stability on Vista. It was a lot of extra work, but we'll have to do fewer hacks in the future."

WFP, a new Vista architecture that lets developers tap into the TCP/IP processing path, was a hard row to hoe. "At times, it seemed like we were an extension of Microsoft QA. They patched and made changes based on what we found while we were developing," Yecies said. Microsoft used WFP to create its own Windows Firewall, which is bundled with Vista.

Even so, Check Point is committed to keeping Zonealarm a free download.

"It's very important to who were are," Yecies said. Zone Labs, which was acquired by Check Point in 2004, made its name by giving away the firewall. "And we think it's the right thing to do," she said. "Our paid users live in a safer world because there are 20 million more protected by the free firewall."

Check Point touted Zonealarm, also the foundation of the Zonealarm Internet Suite that was released Wednesday for Vista, as an "operating system-level" firewall. "Eighteen months ago, we decided that the firewall had to operate at the lowest level of the OS, to monitor every call, every program," said Jordy Berson, Zonealarm product manager.

"There are so many new threats that we need a behavioural-based firewall" to detect and defeat more insidious attackers, including rootkits and drive by-installed keyloggers, Berson said. "Zonealarm does for the computer itself what it was already doing for the network," she said. The Vista firewall tracks 30 different behaviours, such as API calling, logging keystrokes or injecting code, then decides if what it's seeing is safe. If not, it shuts down the process as a more traditional firewall shuts down access to the Internet when it spots a rogue.

The free Zonelarm firewall will be available for download from the Check Point site later today. Zonealarm Internet Security Suite 7.1, priced at US$39.95 (a three-user pack is US$49.95) should also appear later today. Customers with current subscriptions to earlier editions can update to the Vista version free of charge.
