NHS North West London Cybersecurity Enhancement Case Study

This case study outlines the cybersecurity enhancements implemented by NHS North West London Integrated Care Board (ICB) through Heimdal’s solutions, including Privileged Elevation & Delegation Management (PEDM), Application Control, and DNS Security. The ICB, responsible for securing a large healthcare region, faced significant challenges, including the issuance of local admin rights to all GP practice devices, which created security risks such as unauthorized software installations and insider threats. To address these issues, NHS North West London ICB removed permanent admin rights, allowing for controlled privilege escalation and preventing unauthorized applications. The deployment also included DNS Security to block malicious domains and compliance auditing to meet NHS security standards. The successful implementation was supported by strong leadership and a structured communication strategy, leading to a significant reduction in IT site visits and operational costs while enhancing the overall security posture. This transformation aligns with NHS Cyber Assurance Framework compliance and has established new cybersecurity best practices within the organization.
