Twitter has beefed up their malware defenses by acquiring online security firm Dasient, a post from Dasient’s official blog announced yesterday. Effective immediately, Dasient said they will be taking their talents to the Twitterscape’s revenue engineering team.

From the post:

By joining Twitter, Dasient will be able to apply its technology and team to the world’s largest real-time information network. As part of this merger, Dasient is winding down its business and is no longer able to accept new customers.

We would like to thank our customers, partners, investors, and advisers for all of their support over the years, including Google Ventures, Radar Partners, Floodgate, and Benhamou Global Ventures.

Various officials from Dasient made announcements on their personal Twitter accounts:

Twitter’s been on the move lately, earlier this month acquiring Summify after acquiring another security firm, WhisperSystems, back in November.
