"Effective immediately, we will be bringing our technology, tools, and team to the revenue engineering team at Twitter," Dasient wrote on its company blog.
Known for its anti-malware platform, which can scan web addresses to assess the presence of harmful content, Dasient represents Twitter's second web security acquisition in three months. In November, Twitter bought Whisper Systems, an encryption startup that originally built encryption software for Android.
The purchase of Dasient is the latest sign of San Francisc0-based Twitter's growing dedication to online security, an issue that the company had skimped on in the past. Along with its web address analysis products, Dasient has also created a service that can hunt down malicious online advertising to protect the ads and content of customer websites.
The purchase price was not disclosed in the company's post. Dasient, founded in 2008, is the brainchild of a few ex-Googlers including co-founders Neil Daswani and Shariq Rivzi.
"By joining Twitter, Dasient will be able to apply its technology and team to the world’s largest real-time information network," the company wrote. "As part of this merger, Dasient is winding down its business and is no longer able to accept new customers."
With now over 100 million active users, Twitter is expanding. eMarketer reports that revenues are likely to hit $139.5 million this year, triple what they were in 2010.
