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.

What's included in your Keycloak SSO project
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.
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.
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.
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.
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.
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.
Who This Service Is Perfect For
