Enterprise-level identity management software startup Centrify has raised a new $42 million round of funding, the company announced today.

Centrify provides a cloud-based identity tracking service that gives businesses a way to let employees use a single sign-on (SSO) across multiple platforms (servers, mobile devices, applications). The result is a more secure experience that gives those businesses a greater degree of control over who is accessing data. Centrify said it has over 5,000 clients, including many companies in the Fortune 50 and more than 60 federal agencies.

The startup said it plans to use the additional capital to expand into international markets and further develop its technology. The funding round comes from strategic investors Samsung Ventures, Fortinet Inc., and Docomo Capital.

Founded in 2004, the Sunnyvale, Calif.-based startup has raised a total of $94 million in funding to date.
