TurnTide Inc. was an anti-spam technology company founded in 2004. The firm was created as a spin-off corporation from privacy and anti-spam technology firm ePrivacy Group to bring to market the world’s first anti-spam router. The technology, linking anti-spam detection algorithms with network-level flow controls, was originally marketed by ePrivacy Group under the name “SpamSquelcher”.
TurnTide was acquired by Symantec six months after its creation for $28 million.
