OneLogin

OneLogin provides cloud-based single sign-on, multi-factor authentication, and user provisioning for workforce identity and access management, letting organizations centralize authentication across SaaS applications and enforce consistent access policy from one console. It was one of the earlier independent IDaaS (identity-as-a-service) vendors to reach meaningful enterprise scale, competing directly with Okta and Microsoft Entra ID in the workforce SSO market before being acquired.

Founded in 2009 and originally headquartered in San Francisco, OneLogin was acquired by One Identity — itself a Quest Software business unit — in October 2021, in a deal aimed at giving One Identity a market-leading access management product to pair with its existing privileged access management and identity governance lines. Rather than being folded away or discontinued, OneLogin has continued to operate as a distinct, actively developed product line under the One Identity brand: it was named an Overall Leader in KuppingerCole’s 2025 Access Management Leadership Compass and continues to be marketed and sold as “OneLogin by One Identity” to more than 5,000 customers as of 2026.

The practical effect of the acquisition is that OneLogin now benefits from the resources and existing customer base of a larger identity security portfolio, but competes in an access management market increasingly dominated by Okta, Microsoft Entra ID, and Ping Identity, all of which have substantially larger market share. Independent analyst recognition (KuppingerCole, Gartner Peer Insights) provides real third-party validation of the product’s continued competitiveness, even five years after the acquisition closed.
