Case Study

Industry: Financial Services

Organisation Size: 1,500–2,000 employees

RCS Role: DevSecOps Delivery Lead

Microsoft Platform: Azure | Terraform | Azure Security Baseline | SIEM Integration

A Tier-1 financial institution required a greenfield Azure platform built under strict regulatory and risk constraints.

Security, compliance, and operational governance needed to be embedded from day one. Retrofitting controls post-deployment was not acceptable in a highly regulated financial environment.

The organisation needed a secure foundation that would allow product and engineering teams to move quickly, without increasing risk exposure.

RCS designed and delivered a fully automated Azure platform aligned to Microsoft Cloud Adoption Framework and Azure security best practices.

Key elements included:

• Infrastructure-as-Code using Terraform to ensure repeatable, auditable deployments
• Shift-left DevSecOps approach embedding security controls early in the lifecycle
• Integration of SIEM and cloud-native security tooling for continuous monitoring
• Codified policy enforcement to prevent configuration drift
• Role-based access controls aligned to least-privilege principles

Security controls were not layered on after deployment, they were designed directly into the platform architecture.

The institution launched a secure, governed Azure platform with:

• Security embedded into every deployment
• Reduced configuration drift through automation
• Improved audit readiness and operational visibility
• Faster delivery cycles without compromising regulatory posture

The result was a scalable Azure foundation capable of supporting long-term growth under strict compliance requirements.
