Anti-malware firm Dasient has announced its sale to microblogging site Twitter.
In a blog post, Dasient said the acquisition was "effective immediately" and it would be bringing its technology, tools and team to the revenue engineering team at Twitter.
Dasient describes itself as a "web anti-malware technology" provider with technology that scans the web and harnesses "the power of data to mount defences against future malware attacks".
In 2009, Dasient launched a web anti-malware platform that was capable of scanning URLs and websites for the presence of harmful content, and followed that in 2010 with an 'anti-malvertising' service.
Dasient was founded by former Google engineers Neil Daswani and Shariq Rizvi, and former McKinsey strategy consultant Ameet Ranadive. Daswani was
senior security engineer and product manager at Google before becoming CTO of Dasient, while Rizvi was a software engineer at Google before becoming vice-president of engineering at Dasient.
Dasient said: “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.”
Alisdair Faulkner, chief products officer at ThreatMetrix, said: “Unlike Google, which has the luxury of pre-screening sites before adding a URL to its index, Twitter is about what's being shared now. The shortened URL is Twitter's Achilles heel and a malware mind-field for consumers.
“Consumers and impostors alike are sharing tiny tidbits laced with malice. This acquisition is a win for Twitter and a loss for other social networks, publishers and advertisers that increasingly need real-time cyber crime protection.”
