Computer Associates is buying Tiny Software for an undisclosed amount.

CA's vice president of eTrust Security Management, Sam Curry, said the buy was primarily for Tiny's firewall software development kit, which will fill a gap in CA's own product line. It's expected the Tiny technology will be added to desktop products that also combine CA's anti-virus and anti-spyware software (acquired last year from PestPatrol).

CA will continue to support and market the Tiny Software line of Tiny Personal and Tiny Server firewalls directly to consumers and business - which have an estimated two million customers at present.

"This firewall, elegantly designed, has been popular with high-tech users," noted Curry. "We've had our own eTrust firewall from years ago, but frankly this is better."

Tiny earlier this year announced its 2005 product line of firewalls, detailing varying types of spyware-related protection, such as preventing code injection. More recently, it released Tiny Firewall 64, a firewall for 64-bit Windows operating systems.
