Centrify, the provider of an identity and access management platform, has closed a $42 million financing round led by Accel, Sigma West and Mayfield Fund, bringing its total to-date funding to about $94 million. Also participating in the round were Samsung Ventures, Fortinet and Docomo Capital. Centrify previously raised a $16 million Series D round (led by Index Ventures) at a $127 million valuation in August 2011. The company provides unified identity services across data center, cloud and mobile environments that result in a single sign-on for users and a simplified identity infrastructure for IT. Centrify will reportedly use the new capital to expand its product offering and grow internationally.
