How to Assess Your Healthcare IT Suppliers' Cybersecurity: A Practical Guide
Your EPR vendor has privileged remote access to your clinical network. Your pathology software provider processes thousands of patient results daily. Your managed print company collects output logs from every printer in your organisation. Each of these suppliers is a potential attack vector — and you are responsible under UK GDPR for ensuring they have appropriate security measures in place. Yet most healthcare organisations have no systematic programme for assessing supplier security, relying instead on contractual clauses that are rarely verified.
62% of healthcare data breaches involve a third-party vendor — yet fewer than 30% of NHS organisations have a formal supplier security assessment programme.
A Risk-Based Approach to Healthcare Supplier Security
Not all suppliers warrant the same level of scrutiny. A practical risk-tiering approach classifies suppliers as: Tier 1 (high risk — direct access to clinical systems or patient data; require Cyber Essentials Plus certification, completed security questionnaire, right-to-audit clause, and annual review); Tier 2 (medium risk — access to administrative systems or aggregated non-identifiable data; require Cyber Essentials certification and security questionnaire); Tier 3 (low risk — no system or data access; standard contractual data processing terms). This tiering ensures effort is focused where it matters while creating a defensible paper trail for ICO or DSPT purposes.
What to Include in a Healthcare Supplier Security Questionnaire
A proportionate Tier 1 supplier security questionnaire for healthcare should assess: what data or systems the supplier accesses; whether the supplier holds Cyber Essentials Plus or ISO 27001 certification; how the supplier manages privileged access to NHS systems (MFA, access logging, session recording); what the supplier's patch management and vulnerability management processes are; how the supplier would notify you of a security incident affecting your data; and whether the supplier has ever had a data breach affecting NHS clients. Panorays, deployed by Kyanite Blue, automates continuous external security assessment of suppliers based on their internet-facing footprint — supplementing questionnaire evidence with real-world technical data.
