How Graphnet Health Transformed Their Cyber Defence with CyberOne & Microsoft Security

Graphnet Health is the UK’s leading provider of shared care records and population health solutions, playing a pivotal role in enhancing patient outcomes across health and social care systems. With an extensive Microsoft Azure environment supporting around 300 users, Graphnet required an advanced cyber security framework capable of safeguarding critical healthcare data in an increasingly complex digital landscape.

The Challenge

Graphnet faced multiple cyber security challenges due to its complex Microsoft Azure environment and high activity volume across cloud workloads. Additionally, they needed a seamless migration and optimisation of their existing in-house developed security playbooks.

Having previously engaged a Managed Security Provider (MSSP) to deliver a 24x7 SOC service, they fell short of expectations, resulting in a consequential loss of confidence in the service. Graphnet, therefore, urgently required a partner who could deliver proactive managed detection and response (MXDR) with minimal internal overhead.

Selecting The Right Partner

After an extensive market review and competitive tender, Graphnet selected CyberOne for its healthcare industry experience, proven expertise and capability in delivering comprehensive, proactive MXDR services through Microsoft Sentinel. CyberOne’s CREST-certified SOC team stood out due to their proactive approach and ability to deeply integrate with Graphnet’s operational requirements.

MXDR as a Service & Assure 365

CyberOne delivered a robust Managed Extended Detection and Response (MXDR) as a Service through their Assure 365 Managed Microsoft Security Solution, leveraging their deep expertise in the healthcare industry, CyberOne executed:

• A comprehensive audit of Graphnet’s existing Microsoft Sentinel environment.
• Migration and optimisation of Graphnet’s established playbooks.
• Creation of new playbooks aligned with MITRE ATT&CK frameworks.

Additionally, CyberOne integrated proprietary tools within their modular Assure 365 service, enhancing operational efficiency:

• IRIS: An AI-powered automation engine providing real-time alert triage to reduce analyst workload dramatically.
• Hyperion: An actively updated rulebook featuring over 1,000 tailored detection rules aligned to MITRE ATT&CK for increased threat visibility.
• Athena: A powerful threat intelligence programme enabling proactive threat detection and rapid response.

An Immediate Impact & Long-Term Benefits

Graphnet quickly saw measurable improvements:

• Reduced Internal Workload: Dramatic decrease in alert fatigue, allowing the internal team to focus on strategic initiatives rather than day-to-day firefighting.
• Enhanced Threat Detection & Response: Real-time analytics facilitated faster threat containment and streamlined incident resolution.
• Improved Compliance Posture: Continuous monitoring and tailored reporting kept Graphnet aligned with healthcare regulations.
• Future-Proofed Security: The scalable platform is now well-equipped to adapt and grow with Graphnet’s evolving needs, offering sustainable and robust cyber defence
