HQ: San Francisco, United States · E-learning · Cybersecurity · Identity Management · 1001-5000 employees · Est. 2009 · Trust A · Hiring 366, 26 new
Okta is an American identity company founded in 2009 that manages who can log in to what across an organisation's applications, and it built its position by being neutral between the cloud vendors rather than tied to any one of them. Its workforce identity products handle single sign-on, multi-factor authentication and lifecycle management for employees, while Auth0, acquired in 2021, provides the same capability for developers building customer-facing applications. Headquartered in San Francisco and listed on Nasdaq, it suffered a serious support-system breach in 2023 that put its own security practices under scrutiny in a category built entirely on trust.
