Security Plane · Identity & Access
Identity platform for single sign-on, multi-factor authentication and user lifecycle management.
Okta is the vendor-neutral commercial option in this category, and that independence is the point: it is not tied to a productivity suite, so it brokers identity across whatever estate you actually run.
It sells two platforms rather than one, a workforce platform under its own name and a customer identity platform under the Auth0 name, and they are licensed and priced quite separately.
Its product breadth is the widest of the three. Alongside single sign-on and multi-factor it sells governance, privileged access, identity threat detection and posture management as first-party products.
Privileged access deserves particular note, because it is the only one of the three to offer it. That line absorbed Axiom Security in September 2025, extending control to cloud, software service and database resources.
Its threat detection line was similarly reshaped by buying Permiso Security, which closed in August 2026 and brought behavioural analytics across human, machine and agent identities.
Deployment is cloud only. There is no self-hosted option; on-premises reach comes from lightweight agents and a gateway that connect outward to your tenant.
Its current direction is agent identity, with a dedicated product generally available since April 2026 that registers agents in the directory, detects shadow agent use in the browser and can deactivate an agent outright.
Read that product's boundaries carefully, because several capabilities people assume are shipping are not. Agent to agent delegation, a gateway control plane and agent threat detection are all published as not yet generally available.
A separate and free capability arrived in August 2026: agent single sign-on, built on an open cross-application access standard extending OAuth, included in core plans rather than sold as an add-on.
Its support system incident of October 2023 affected 134 customers, under one percent, with five sessions hijacked, and no later incident is disclosed.
The same headings are used for every identity & access entry, so two tools can be read side by side.
SubscriptionFrom $6 per user per month, 1500 USD annual minimum
Genuinely published, unusually for this category, but only at suite level. Workforce suites list at $6, $14 and $17 per user per month billed annually, with the top two tiers quote-only, and a $1,500 annual contract minimum. Every add-on is priced on request, including governance, lifecycle management, privileged access, threat protection, posture management and the agent product. Customer identity publishes a $3,000 monthly platform fee with the suites above it quote-only. A 30-day workforce trial is published, and a developer plan for ten monthly active users that does not expire.
Okta was founded in 2009 by Todd McKinnon and Frederic Kerrest, who describe themselves as having created the identity-as-a-service category, and it is headquartered in San Francisco with offices in fifteen countries. It is public on Nasdaq as OKTA, with a fiscal year ending in January. For the quarter to July 2026 it reported total revenue of $805m, up 11% year on year, with subscription revenue of $793m, remaining performance obligations of $4.86bn and free cash flow at 28% of revenue, guiding to $3.22bn for the full year. It reports more than 20,000 customers including two-thirds of the Fortune 100. Its published acquisitions are Axiom Security, closed September 2025, and Permiso Security, closed August 2026; the Auth0 deal terms are not on a current first-party page.
