One Access Layer for Every API.
Open APIs to partners, customers and AI without expanding your attack surface or slowing delivery. The Curity Identity Server turns every API call into a verified and auditable access decision.
For API-first organizations that need to move fast and stay open
Your API ecosystem is growing faster than your access model. Every endpoint depending on custom authorization solutions adds maintenance, governance and audit gaps. Inconsistent API access control across endpoints is where breaches start.
Open your APIs with confidence. Lock down the attack surface
Secure every API
Every API that rolls its own authentication is a maintenance liability and a security risk. The Curity Identity Server centralizes token issuance to ensure consistent API access control across every endpoint.
One access layer for every API consumer
Partners, customer apps, internal services, AI agents all get precisely scoped access through the same platform. One authorization layer that scales with what you build.
Accelerate partner and developer onboarding
New partners and developers onboard without tickets, manual provisioning or security delays. Dynamic Client Registration automates onboarding while keeping access tightly controlled.
Grow your API ecosystem without growing cost or complexity
Flat-rate licensing means the count of APIs, tokens, partners or AI agents doesn't change the price. Your API access control layer scales with the platform, your cost holds.
How it works in practice
Three patterns API-first organizations run in production today.
A mobile app or single page app needs backend access on behalf of a logged-in user. Tokens can't live in the browser. Secrets can't live in the client. Curity secures the flow using OAuth 2.0 and Token Handler, without exposing tokens or secrets to the frontend. Works with any gateway: Kong, Apigee, AWS API Gateway.
Your APIs speak standards. Your access layer should too
Open standards keep your API ecosystem portable, interoperable and easier to govern over time. OAuth 2.0, OpenID Connect, FAPI 2.0, Token Exchange, DPoP and SCIM, with OpenID Foundation certification and flexible deployment across self-hosted, hybrid or cloud, with configuration as code.
Proven across API ecosystems serving millions of daily transactions
There's not a single ICA service that doesn't use Curity in one way or another.
ICA Gruppen, Sweden's largest retail group, started with a few internal applications and grew the Curity Identity Server into the API access control layer for every service across retail, banking, pharmacy and real estate. Internal APIs, partner integrations, customer-facing services — all governed through one platform. One access decision model for every API consumer.
