Case Study
Secure Hybrid Identity for UK Public Sector Regulator
Industry: Public Sector (Regulatory)
Organisation Size: >1,000 employees
RCS Role: Cloud Identity & Security Partner
Microsoft Platform: Azure Active Directory | Azure AD Connect | RBAC | Azure Site Recovery | Azure DevOps | Terraform
The Challenge
A UK regulatory authority operated a legacy on-premises Active Directory and messaging environment that required modernisation and secure integration with Azure.
Regulatory expectations around identity governance, resilience, and auditability were high. The organisation needed to strengthen access control, improve operational visibility, and ensure continuity, without disrupting core regulatory functions.
The challenge was to transform identity into a secure, governed hybrid platform capable of supporting long-term digital growth.
The Approach
RCS led the restructuring of the on-premises Active Directory environment and securely extended identity services into Azure.
The programme focused on creating a central source of truth for identity and access, embedding governance and automation from the outset.
Key elements included:
- Design and implementation of a secure hybrid identity architecture
- Role-Based Access Control (RBAC) models for users and service accounts
- Infrastructure-as-Code for domain controller and platform deployments
- Automated build and deployment pipelines using Azure DevOps and Terraform
- Integration of backup, disaster recovery, and Azure Site Recovery
- Strengthened auditing and logging aligned to regulatory requirements
Identity governance was treated as foundational architecture, not an afterthought.
The Outcome
The authority transitioned to a modern, resilient hybrid identity platform with improved governance and operational stability.
- Centralised and standardised identity management
- Stronger access control and least-privilege enforcement
- Improved audit readiness and traceability
- Enhanced resilience through automated recovery capabilities
- Reduced operational risk through codified infrastructure
The organisation established a secure identity backbone capable of supporting regulatory obligations and future cloud adoption initiatives.
Delivery Impact
- Hybrid identity platform standardised across environments
- Automated infrastructure deployment for domain services
- Strengthened audit and compliance posture
- Improved resilience through integrated disaster recovery
