The ICSA Labs PC Firewall Certification program is an independent and comprehensive process that vigorously tests, assesses and validates the security of PC firewalls relied upon by individual users in remote locations. The first products to receive ICSA Labs PC Firewall Certification include Symantec Corporation's (Nasdaq: SYMC) Norton Personal Firewall for Microsoft's Windows 98, Windows ME, Windows NT Workstation, and Windows 2000 Professional; Tiny Software's Tiny Personal Firewall for Windows 2000; and Zone Labs' ZoneAlarm Pro for Windows 2000. "For many of our customers, the ICSA Labs Certification plays an important role in their evaluation process, knowing it validates the product's performance against the Lab's testing criteria," said Gregor Freund, CEO and co-founder of Zone Labs.
