Detailed Review
Curity AB is a Swedish limited company founded in Stockholm in 2015, registration number 559017-0196, at Sankt Göransgatan 66. Its terms of use, last updated on 30 March 2026, name that entity as the contracting party. The product is an identity server built around the standards rather than around a console: OAuth, OpenID Connect, FAPI, SAML and SCIM, with OpenID Foundation certification confirming the implementation conforms.
There is no Curity-operated SaaS. The deployment page describes on-premise, single-cloud, multi-cloud and hybrid installations and nothing else, which is a stronger residency position than any hosted service can offer — the data sits where you put it, and no vendor region picker is involved. It also means the whole operational burden is yours, and there is no way to try the product without standing it up.
The Community Edition is free and the paid editions — Standard, Enterprise and Token Handler — are sold on a flat annual subscription with the price on request, plus a 14-day trial.
Free is not the same as open source here: the code is not published under an open licence. Since May 2023 GRO, a Danish private equity fund, has held an investment in the company, with the size of the stake not stated. Curity's own pages name no ISO 27001 or comparable audit.
What Curity does well
- Swedish AB in Stockholm, founded 2015, registration number 559017-0196
- You choose the infrastructure: on-premise, single-cloud, multi-cloud or hybrid
- OAuth, OpenID Connect, FAPI, SAML and SCIM, certified by the OpenID Foundation
- Free Community Edition, plus a 14-day trial of the paid editions
- Flat annual subscription rather than billing per active user
Where Curity falls short
- No price published for the paid editions — flat annual subscription on request
- Free Community Edition, but the product is not open source
- No vendor-run service at all, so every deployment is your operation
- No ISO 27001 or comparable independent audit stated on its own pages
- Part-owned since 2023 by GRO, a Danish private equity fund, with the stake undisclosed
Standout feature. It runs on hardware you chose, because there is no Curity cloud to run it on instead.
