Case Study: NHS Northumbria achieves stronger cyber resilience and reduced IT overhead with Heimdal Security

Stronger Healthcare Security with Heimdal Protecting NHS Northumbria

NHS Northumbria, a healthcare trust managing a large IT estate of 11,000 endpoints, faced increasing DNS-layer threats from hybrid working and extensive third‑party connections while operating with a lean IT team. To close these gaps without adding complexity, the trust engaged Heimdal Security and deployed Heimdal DNS Security to provide autonomous DNS‑level protection and actionable insights.

Heimdal Security rolled out Heimdal DNS Security across all 11,000 endpoints, autonomously detecting and blocking threats that bypassed other tools—such as malicious browser extensions and unauthorized software—while integrating smoothly with existing security controls. The deployment delivered immediate threat mitigation, stronger cyber resilience, minimal daily IT overhead, and actionable intelligence that helped improve NHS Northumbria’s overall security posture.
