Dasient was an internet security company headquartered in Sunnyvale, California. It was founded in 2008 [1] and launched its first product in June 2009.[2][3] Dasient was acquired by Twitter in January 2012.


Dasient provides cloud-based anti-malware services for protecting businesses against web-based malware and malvertising.[4][5]

Dasient's Web Malware Analysis Platform uses a dynamic, behavioral-based engine - based on sophisticated algorithms and anomaly detection technology - to defend against the latest attacks using up-to-date intelligence about malware. This platform includes a system of highly instrumented virtual machines to simulate what actual users would experience when visiting a particular web page or viewing a specific online ad.[6]


The company was founded by former Google personnel Neil Daswani and Shariq Rizvi, and former McKinsey strategy consultant Ameet Ranadive.[7][8]

Dasient was named by Network World as one of ten startups to watch in 2010.[9]

The company received seed funding from Mike Maples, ex-Verisign CEO Stratton Sclavos, and ex-3Com/Palm chairman Eric Benhamou.[10] In February 2011, it was announced that Google Ventures invested in Dasient.[11]

Dasient was acquired by Twitter in January 2012.[12][13][14][15][16][17]
