Healthcare Network Implements Zero-Trust Architecture

A 12-hospital network deployed a full zero-trust security model across 8,000 endpoints, achieving ISO 27001 certification and passing GDPR audit.

The Challenge

Following two near-miss ransomware incidents, the healthcare network needed to fundamentally rearchitect its security posture across 12 hospitals, 8,000+ endpoints, and a hybrid cloud estate — while maintaining 24/7 clinical operations.

Our Approach

Saints & Masters deployed a zero-trust architecture based on Microsoft's integrated security stack — Entra ID for identity governance, Defender for endpoint protection, Sentinel for SIEM, and Intune for device management — with a managed SOC providing 24/7 threat monitoring.

Outcomes & Results

  • Zero-trust architecture deployed across all 12 hospitals
  • 8,000 endpoints brought under unified management
  • ISO 27001:2022 certification achieved within 14 months
  • GDPR technical controls audit passed with no findings
  • Two subsequent ransomware attempts detected and blocked automatically

The zero-trust deployment has fundamentally changed our security posture. We now have visibility and control we never had before.
