Okta has raised $25 million for its solution to cloud-based enterprise application identity management. The round was led by new investor Sequoia Capital, with participation from  existing investors Andreessen Horowitz, Greylock Partners, Khosla Ventures, and Floodgate. Okta establishes user identity on both cloud applications and legacy and on-premise programs, saving users from having to use multiple identity management products.
