Twitter Acquires Online Security Firm Dasient To Beef Up Malware Protection

In a bid to strengthen its resolve against malware and other malicious attacks, Twitter has acquired Dasient, an internet security company founded by ex-Google staffers Neil Daswani, Shariq Rizvi and Ameet Ranadive, for an undisclosed sum.

The move appears to be largely a talent purchase, and Dasient will be bringing their “technology, tools, and team” to the revenue engineering team at Twitter, effective immediately.

Dasient announced the acquisition on their blog:

Since its inception, Dasient has been focused on solving web-scale security problems involving malware and other types of online abuse. 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.

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.

Dasient is joining Twitter’s revenue engineering team because “they have a deep understanding of advertising-platform security issues,” says Twitter spokesperson Rachael Horwitz.

Malware and other site-wide exploits have been a problem for Twitter essentially since the platform first opened its doors (one early, notable example being the Mikeyy worm). In 2010, Twitter launched their own URL shortener,, in a bid to further combat the spread of malicious links.

The Dasient buyout is the latest in a series of talent purchases by Twitter, which has included Summify, AdGrok and TweetDeck.
