Kerio Technologies is ending distribution and support for its Kerio Personal Firewall because it cannot compete against bundled security products.
The desktop firewall has been available from Kerio since 2002, and has been downloaded by more than 2m customers, said the company. The basic version is free and a paid-for version offers additional features such as web filtering.
The firewall will not be available after 31 December, although existing customers will get support until the end of next year.
Microsoft already bundles a free personal firewall with its XP operating system, and Dell PC users, for instance, are offered a complete security bundle of firewall, anti-virus, anti-spam and privacy protection from McAfee once they receive their machine.
Kerio will now concentrate on selling its server-based WinRoute firewall to companies.
