Symantec buys anti-spam firm TurnTide

For the routing technology

In brief Symantec has bought TurnTide, an anti-spam start-up, for $28m cash. The acquisition comes on hot on the heels on Symantec's much larger deal to buy spam filtering firm Brightmail for $370m.

TurnTide launched its first anti-spam router product in February. Its technology works by limiting the bandwidth available to machines identified as sending out spam. The acquisition was finalised on Thursday, but news of the deal emerged yesterday when TurnTide posted a notice on its website. ®
