DEFRA: DevSecOps & Multi-Tenant Security Architecture

The Department for Environment, Food & Rural Affairs (DEFRA) needed to enhance cloud security across its multi-tenant Azure environments, improve threat detection and response, and prepare for regulatory audits while ensuring consistent Infrastructure as Code (IaC) security.

To strengthen DEFRA’s cloud security posture and threat response capabilities across Azure environments using modern DevSecOps and IaC best practices.

Accelix Digital delivered proactive threat detection and response using Azure Defender and Sentinel, secured network infrastructure with Terraform and ARM, integrated Azure Lighthouse for cross-tenant visibility, and conducted staff workshops to uplift internal security capabilities.

During the 12-month engagement, DEFRA achieved:

• Resolved high-priority vulnerabilities, including Log4J, across environments
• Established secure, compliant IaC baselines using Terraform
• Improved visibility and reduced threat response times with Azure Sentinel
• Enabled cross-tenant visibility and governance via Azure Lighthouse
• Upskilled internal staff on secure IaC deployment and vulnerability management
