Open Source SSO Built for Real-World Systems

Keycloak is widely recognized as one of the best IAM software options for teams that need flexibility, transparency, and full control over identity data. But out-of-the-box Keycloak covers maybe 60-70% of what a production system needs.

Perfsys specializes in closing that gap. We adapt Keycloak to real operational needs: from customer portals and internal tools to multi-brand and enterprise-scale systems.

Centralized SSO Login Across Applications

We set up Keycloak as your central identity provider with SSO across customer-facing apps, internal systems, and third-party services using OAuth2 and OpenID Connect.

problems icon

Identity Federation & Directory Integration

We connect Keycloak with your existing identity sources such as Active Directory or legacy user databases. Your users keep their current credentials without re-registering.

problems icon

Secure Architecture with Public and Private Access

We deploy Keycloak on AWS with public endpoints for customer authentication and admin access isolated in private networks. Separate environments for dev, staging, and production.

problems icon

Extending Keycloak via Keycloak API

We extend Keycloak using the Keycloak API: advanced user search, custom admin workflows, secure impersonation for support teams, and integrations with your internal tools.

problems icon

Custom MFA and Authentication Flows

Email-based MFA, device recognition and trusted sessions, conditional MFA based on context or risk level. Stronger security without frustrating your users.

problems icon

Branded Login & Communication

Custom login screens, registration flows, account pages, and email templates for each brand or product. One identity platform behind the scenes, multiple brand experiences in front.
