Companies Using Okta

Okta is the identity platform most often named in enterprise security stacks, and it is also one of the hardest to count from the outside. Our crawl of 29.9M active business domains verifies 1,529 organizations running Okta identity code on their own web properties as of August 24, 2026. Okta's own reporting puts its customer base near 20,000 organizations. Both numbers are correct, and the difference between them is the most useful thing on this page.

The reason is architectural. Most Okta seats are workforce identity: an employee opens a company tenant hosted on Okta's own infrastructure, signs in, and lands in Salesforce or Workday. None of that touches the employer's public website, so no crawler can see it. What we can see is the other half of the product, where identity is deployed on the customer's own domain: a branded sign-in page, a partner portal, a student login, a customer account area. Treat 1,529 as a floor on Okta's total customer base and as something more precise than a floor for the segment it actually measures.

"We publish what we can verify on a domain we crawl, and for Okta that means customer-facing identity, not the workforce tenants nobody outside the company ever loads. A number with a known boundary is worth more than a bigger number with a vague one." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Look at where the detections land and the segment defines itself. AMD signs customers in at account.amd.com. Waste Management uses ssologin.wm.com, First Citizens runs treasuryapps.firstcitizens.com, Guardian Life uses signin.guardianlife.com, and NOV uses login.nov.com. The University of Alabama runs mybama.ua.edu and the State of South Carolina runs login.sc.gov. These are named, branded, purpose-built entry points. Nobody stands up a subdomain like that for a pilot, which is why this list behaves differently from a list of sites that happen to have a script installed.

The industry ordering is the finding that surprised me. Higher Education is the single largest industry at 9.8% of the 553 companies with a known sector, ahead of Software Development at 9.6% and Financial Services at 8.9%. Universities are not the biggest identity buyers in dollar terms, but they are the most visible ones, because campus identity is public by design. Every student and staff member signs in through a branded address that anyone can load. Insurance (6.3%) and Hospitality (6.2%) show up for the same structural reason: broker portals and loyalty logins are customer-facing by definition.

The company-size curve confirms the enterprise weighting. Companies with more than 1,000 employees are 31.5% of the sample, and the largest single band is 1,001 to 5,000 at 20.5%. Age tells the same story from another angle: 27.1% of these organizations were founded before 1960. Old institutions with large user populations and compliance obligations are exactly who replaces an aging in-house login with a managed identity provider.

The comparison buyers ask about most is Auth0, which Okta acquired in 2021 and still sells as a separate product. Our data shows two genuinely different footprints. Auth0's largest industry is Software Development at 22.8%, more than double its next sector, because Auth0 wins where a developer picks an authentication SDK. Okta's largest is Higher Education. Same owner, opposite centers of gravity, and the split is a reasonable proxy for how each product is bought: one by an engineering team choosing a library, the other by an IT organization standardizing an institution. Clerk sits further along the same developer axis.

The rivalry that matters commercially is less visible in the category ranking. Okta places 19th of 50 with 0.16% share, but the entries above it are mostly social login buttons: Facebook Login on 621,585 domains and Google Sign-in on 219,115 are one-click options on consumer sites, not platforms competing for an identity budget. Two rows up sits the comparison that counts. Microsoft Entra ID appears on 1,540 domains against Okta's 1,529. On the web-visible layer, Okta's largest competitor is running level with it.

The surrounding stack reads as enterprise infrastructure throughout. Cloudflare fronts 30.4% of Okta domains and Akamai another 8.2%, which is a high Akamai share by any measure and reflects how often a login portal sits behind a managed edge. OneTrust appears on 19.2%, so roughly one in five of these organizations pairs identity work with a formal consent program. Google Analytics covers 42.5%, and the presence of Adobe Analytics on 5.8% points at organizations measuring the sign-in funnel as a conversion path rather than a formality.

"A branded login subdomain is the cleanest buying signal in our data. It means somebody scoped a project, moved a domain, and shipped it. That is a very different prospect from a company evaluating options." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales Signals

• A branded sign-in subdomain such as login.company.com or account.company.com indicates a funded, shipped identity project rather than an evaluation.
• Higher Education leads the sample at 9.8%, so campus identity teams are a reachable segment with public, verifiable deployments.
• 31.5% of these organizations exceed 1,000 employees, which usually means procurement, a security review, and a multi-year contract cycle.
• 19.2% also run OneTrust, so consent and privacy tooling is a reliable adjacent sell into the same buying committee.
• 27.1% were founded before 1960, a population that tends to be migrating away from legacy directory infrastructure rather than starting fresh.
• 414 of the 576 matched companies with a known country are US-based, so a North American territory covers most of the addressable list before any international expansion.

One caution on reading the trend line. Okta's detectable footprint grew quickly from 2021 through 2023 and has been broadly flat since, but that shape describes web-visible deployments only, and the set of domains we crawl turns over every month while our detection signals widen over time. A flat line here is not evidence that Okta stopped growing; it is evidence that the customer-facing slice of its estate has been stable while the workforce side, which we cannot see, went on selling. We explain what a crawl can and cannot establish in our note on technology detection methods, and it applies with unusual force to identity software.
