“Effective immediately, we will be bringing our technology, tools, and team to the revenue engineering team at Twitter”, Dasient wrote Monday on its blog.

“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”, the company wrote.

Dasient will be integrated into Twitter’s “revenue engineering team because they have a deep understanding of advertising-platform security issues,” Rachael Horwitz, a spokesperson for Twitter, told

In addition to providing security services, Dasient also provides research on malware. At the 2011 Black Hat conference, the firm released research showing that privacy and security threats in mobile applications are on the rise, especially for the Android platform.

After analyzing around 10,000 apps downloaded from the Android Market, Dasient researchers found that 842 of them were leaking personal information. The research also highlighted the fact that drive-by downloads are a major issue for Android users to contend with.

This marks the second information security acquisition by Twitter in three months. In November last year, Twitter acquired Whisper Systems, a provider of encryption technology and the brainchild of hacker and security researcher Moxie Marlinspike.
