DasientTwitter has acquired security startup Dasient, a company that specializes in fighting spam and malware.

The Dasient team will be plugged into Twitter's "revenue engineering" group as Twitter monetizes with self-serve ads, reports TechCrunch.

In terms of the size of the team this acquisition was a large one, said TechCrunch's sources.

It could be a match made in heaven -- the most likely scenario seems that Twitter wants to protect its self-serve ad product from being used as a vehicle for spam.

With Dasient being well-versed in anti-spam and anti-malware efforts, it could be just what Twitter needs to maintain the product.
