THE PROBLEM

The hidden risk of legacy IAM

Why enterprises must modernize legacy IAM before it becomes a liability

With global cybercrime projected at $10.5 trillion annually, outdated IAM platforms – CAS servers, custom LDAP directories, legacy extranets with homegrown authentication – create risks that compound over time, making IAM modernization essential for identity-centric security – the shift from perimeter-based to identity-driven protection. They cannot support Zero Trust, lack modern federation protocols, and become increasingly expensive to maintain.

Watch our short explainer to understand the key risks enterprises face when delaying IAM modernization.

  • 61% of data breaches involve credential misuse – legacy systems amplify risk
  • No support for modern protocols (OAuth 2.0, OIDC, SAML 2.0)
  • Password-based authentication with no MFA capability
  • No centralized audit trail for NIS2/KSC compliance
  • Fragmented identity silos across merged entities
  • Vendor lock-in with no API-driven migration path

Our Process

IAM modernization, step by step

We deliver both full-scale “big bang” cutovers and phased, progressive migrations – choosing the right approach based on your timeline and regulatory deadlines. Each approach is designed for enterprise environments where downtime is measured in revenue lost. Whether driven by NIS2 compliance deadlines or the need to eliminate password-based vulnerabilities, our IAM transformation process addresses the root causes of legacy identity risk.

FAQ

Frequently asked questions about IAM modernization

We have experience migrating a wide range of legacy identity systems to Keycloak, including CAS (Central Authentication Service), custom LDAP directories, proprietary SSO platforms, legacy extranets with homegrown authentication, customer-facing identity platforms (CIAM) for external portals and partner ecosystems, and various commercial IAM solutions. Our approach includes backward-compatible API layers, phased user migration, and password separation strategies to ensure zero disruption during the transition.

Timeline depends on the complexity of your legacy environment. A focused migration for a single legacy IAM system can be executed in weeks. Large-scale enterprise transformations – involving multiple legacy systems, tens of thousands of users, and complex application integrations – typically span 3 to 9 months using our phased migration factory approach. We prioritize critical applications first and migrate users in controlled batches to minimize risk.

Both. As a Red Hat Advanced Partner, we deploy either open-source Keycloak or Red Hat Build of Keycloak (RHBK) depending on your requirements. RHBK is recommended for regulated environments that require vendor-backed SLAs, certified security patches, and long-term support cycles. Both options are deployed on enterprise infrastructure — OpenShift, Kubernetes, or on-premises — with the same level of architectural rigor.

Our migration methodology is designed for zero-downtime transitions. We run Keycloak in parallel with your legacy system during the migration period. Users are migrated progressively — either through forced migration at next login or batch migration of historical accounts. Backward-compatible APIs ensure that existing application integrations continue to work throughout the process. Legacy systems are decommissioned only after full migration is verified.

The NIS2 directive (and its Polish transposition, the KSC amendment) mandates deployment of MFA, access governance, identity lifecycle management, and incident reporting capabilities within 12 months of enactment. Legacy IAM systems typically cannot satisfy these requirements. Keycloak-based modernization provides centralized MFA enforcement, RBAC policies, immutable audit trails, and integration with national S46 incident reporting — directly addressing the compliance timeline. Essential entities face fines of up to 2% of global turnover for non-compliance.

We provide ongoing managed Keycloak operations as part of our modern IAM solutions – 24/7 monitoring, security patching, version upgrades, performance tuning, and configuration management. Many of our enterprise clients continue with our managed service for years after the initial migration. We also support progressive expansion: adding passwordless authentication, adaptive MFA, federated identity for partners, and self-service portals as your needs evolve.

Moving legacy IAM configurations directly into Keycloak — replicates old problems in a new system. We avoid this by applying proven IAM modernization strategies that redesign identity architecture during the migration: rationalizing legacy access policies, consolidating fragmented user stores into a single source of truth, and replacing proprietary protocols with OAuth 2.0, OIDC, and SAML 2.0. Our phased migration factory approach introduces Keycloak capabilities incrementally — SSO first, then MFA, then federation — with backward-compatible APIs maintaining business continuity at every stage. Legacy systems run in parallel until each migration phase is validated, so there’s never a risky “all-at-once” cutover unless the timeline demands it.
Avoid a pure “lift and shift” of legacy on-premises IAM into the cloud by first assessing specific needs, existing identity architectures, and business priorities. Adopt a phased deployment that modernizes iam functionality, introduces iam and identity governance iteratively, and tests integrations with enterprise applications. Prioritize a single source of truth, establish access control baselines, and incorporate risk management to prevent security gaps and ensure a smoother transition that preserves business continuity.

We deploy Keycloak on OpenShift or Kubernetes, which runs consistently across AWS, Azure, GCP, private cloud, and on-premises data centers. Identity federation via OIDC and SAML bridges authentication across all environments, giving users single sign-on regardless of where applications are hosted. For regulated enterprises running legacy on-premises systems alongside cloud workloads, Keycloak acts as the centralized identity broker – federating identity across environments without requiring you to move user data to a single cloud provider. This hybrid portability is critical for NIS2 high-risk vendor phase-out compliance and EU data sovereignty requirements.
A robust deployment strategy uses a modular, organizationally aligned framework that supports hybrid environments and cloud scalability. Implement identity federation, single sign-on, and standardized connectors for enterprise applications to streamline access across multicloud and legacy systems. Focus on interoperability, scalability, and a phased approach that preserves existing identity while incrementally introducing new tools and automation to meet business needs.

Keycloak provides the modern authentication and privileged access foundation that Identity Governance and Administration (IGA) platforms depend on. Natively, Keycloak enforces RBAC/ABAC policies, step-up authentication for sensitive operations, time-limited access tokens, and session-level controls — handling the PAM layer directly. For full lifecycle governance — automated access reviews, entitlement certifications, segregation of duties enforcement, and joiner/mover/leaver workflows — Keycloak integrates with IGA platforms like SailPoint and Saviynt via SCIM, OIDC, and REST APIs. The critical point: without a modern authentication layer, IGA tools receive fragmented, inconsistent identity data from legacy systems, making access reviews unreliable. Modernizing to Keycloak first gives IGA platforms a clean, authoritative identity source to govern.

We recommend tracking concrete KPIs that directly reflect migration success: SSO adoption rate across migrated applications, MFA enrollment percentage, mean time-to-provision for new users, number of legacy systems retired, and zero-downtime incidents post-migration. For compliance, monitor NIS2/KSC audit readiness score, percentage of access reviews completed on schedule, and incident response time against S46 reporting requirements. Operational efficiency metrics include reduction in manual identity administration tasks, password reset volume (which should drop significantly with SSO and passwordless authentication), and cost savings from decommissioned legacy IAM license fees. We establish baseline measurements during the discovery phase so progress is quantifiable throughout the engagement.
Track metrics like time-to-provision, number of access-related incidents, percentage of automated access reviews, mean time to remediate risky entitlements, and user experience scores (e.g., single sign-on adoption). Also monitor compliance metrics, scalability indicators (support for increased users/enterprise applications), and reduction in manual workflows. Use these metrics to continuously refine the framework, justify investment in iam tools and ai-driven IAM, and ensure the program aligns with business priorities and regulatory compliance.
