The Dasient team joining with Twitter's

Dasient was founded in 2008 by a team of security experts and ex-Google staff. Its technology scans web addresses to detect harmful content, and the company also operates a service aimed at keeping online advertising free of malware. "By joining Twitter, Dasient will be able to apply its technology and team to the world’s largest real-time information network."

Twitter's long been plagued by malware and spam attacks, and this isn't its first security-related acquisition.--Twitter has acquired Internet security firm Dasient, the Sunnyvale, California startup said on its blog on Monday. Dasient, which describes itself as a cloud-based Web antimalware technology company, introduced in 2010 a service to protect advertisement networks and publishers from malicious ads.--The acquisition fits with Twitter's plans to expand revenue from advertising including promoted Twitter messages and accounts.

The Dasient team is joining Twitter's "revenue engineering" team, he said. Twitter said in a message that "Dasient is joining the flock!", and referred to Daswani's blog post. In 2009, Dasient launched its web anti-malware platform, capable of scanning URLs and websites for the presence of harmful content.

In 2010, Dasient launched the industry’s first anti-malvertising service to protect ad networks and publishers from the scourge of malicious ads. Over the last year, we have been very active in securing the ads and content of the some of the industry’s largest ad networks and web sites.” Twitter advertising’s most likely use of a full staff trained in anti-spam and anti-malware strategy is to protect a product (like Twitter’s self-serve ads for example) from fraud and attempts at abuse.
