In the face of competition from security suite vendors, Kerio Technologies will <A HREF="http://news.zdnet.com/2100-1009_22-5903250.html?tag=zdnn.alert">pull the plug on its desktop firewall product</A> at the end of this year. Kerio will stop offering its Kerio Personal Firewall product as of Dec. 31 but will continue to support existing customers until the end of next year. Kerio is pulling out of the desktop firewall space because it can't compete with security suites that bundle a firewall with antivirus and spyware-fighting software, the company said. Such products are sold by companies including Symantec, McAfee, Trend Micro, and Zone Labs.
