Identity and Authorisation

We design and implement identity and authorization solutions that form the backbone of trust in digital platforms. From Keycloak and OpenFGA to Okta/Auth0, we deliver enterprise-grade IDP and Authorization architectures that are scalable, compliant, and built to last.

Fragmented identity setups and inconsistent access control lead to security gaps, operational overhead, and compliance risks. A solid identity and authorization layer creates trust, simplifies complexity, and scales with your business.

At UFirst, we design architectures that combine security, usability, and flexibility for both customer-facing platforms and internal systems. For example, we have migrated large monolithic applications to modern service-oriented architectures secured by a central Keycloak identity provider and OpenFGA authorization. By integrating OAuth2 Proxy at the edge, we achieve “security by architecture,” ensuring consistent authentication and authorization across all services without adding complexity to each one.

Identity today extends far beyond basic login flows. We design and operate platforms that support complex scenarios such as multi-tenant architectures (HR or B2B portals where each client company has its own users, branding, and data boundaries within one secure system), hybrid identity models (linking corporate logins from on-premise Active Directory with cloud identities like Google Workspace), and delegated authorization (allowing a team lead to approve vacation requests on behalf of others) across services and applications.

Our team works at the intersection of security, infrastructure, and application development, enabling us to integrate identity seamlessly into distributed systems. Whether it’s handling single sign-on across heterogeneous environments or applying fine-grained access control at scale, we build solutions that fit real enterprise needs rather than generic templates.

We deliberately separate identity management, authorization, and application logic so each layer can evolve without disrupting the others. This approach makes large architectures easier to scale, simplifies regulatory audits, and keeps policies transparent and centrally managed. 

By adhering to open standards, we avoid vendor lock-in and ensure long-term flexibility, making it possible to migrate between platforms without major rework. Whenever possible, we favor open-source and European-based solutions that align with data-sovereignty and compliance requirements.

By treating identity as a core architectural layer rather than an afterthought, we give organizations the flexibility to adopt new services, refactor applications, or switch providers without rewriting security foundations.

We have extensive experience managing identity and authorization in traditional setups, giving us a clear understanding of their limitations. Over time, we have led multiple migrations from fragmented systems to unified architectures built on Keycloak, OpenFGA, or Okta/Auth0. These transitions improve security, reduce complexity, and give organizations more flexibility.

The same principles power our own products, giving us practical insight into what works in real production environments. Organizations looking to modernize their identity and authorization can rely on UFirst for end-to-end implementation and operations services. We build secure, scalable, and future-proof foundations so teams can focus on innovation with confidence.
