Positioning guardrails
Best for
- Engineering teams that want to self-host identity on their own infrastructure, including on-prem, hybrid and air-gapped deployments.
- B2C, B2B and B2B2C products that need OAuth2, OIDC, SAML v2, passkeys and MFA delivered through APIs.
- Security and platform teams that need fine-grained authorization for users, services and AI agents.
- Companies that want predictable pricing with unlimited identity providers on every plan.
- Regulated businesses that need GDPR compliance and a HIPAA BAA as they scale.
Ideal size: 20–500 people · Scale-up or enterprise with an engineering team that owns identity infrastructure
Not for
- Teams looking for a no-code identity product they never have to operate or deploy.
- Buyers who expect advanced MFA, threat detection and 24/7 support on a free tier.
- Organizations that want a broad SaaS app marketplace rather than a focused CIAM server.
- Companies without engineering capacity to run or integrate an identity service.
