The NHS Four Pillars: Building a More Resilient & Secure Supply Chain

Why the Four Pillars matter now

The NHS Four Pillars of Cyber Resilience have been introduced as part of the NHS Cyber Security Awareness Month campaign. This initiative comes at a critical time for healthcare. Cyber criminals are increasingly targeting NHS suppliers as the weakest link in the security chain. Consequently, attacks on connected systems are rising, disrupting clinical services and threatening patient data.

As a result, the NHS is raising expectations of its partners. Every organisation within the NHS Supply Chain must be able to demonstrate resilience – not just compliance.

These pillars – Recognise, Respond, Reinforce, Reflect & Recover – define what that resilience looks like. They form the new standard by which NHS buyers will evaluate suppliers’ readiness to operate in today’s threat landscape.

What alignment means in practice

Alignment requires more than ticking compliance boxes. Standards such as DSPT, ISO 27001, Cyber Essentials Plus and IT Health Checks (ITHC) remain essential, yet they do not always prove how systems perform under real-world attack.

True alignment therefore combines:

• Technical assurance, through penetration testing, vulnerability scanning, and continuous monitoring from a 24/7 Security Operations Centre (SOC).
• Governance alignment, ensuring frameworks are implemented, tested, and maintained.
• Cultural reinforcement, achieved through regular Cyber Awareness Training so staff can recognise and respond to threats.

Together, these elements create measurable evidence of resilience across all four pillars.

Pillar by pillar: how suppliers align

1. Recognise

Suppliers cannot secure what they cannot see. Recognition begins with visibility – of vulnerabilities, dependencies, and human factors.

Regular vulnerability scanning and CREST-approved penetration testing uncover weaknesses before attackers can exploit them. In parallel, Cyber Awareness Training helps staff identify phishing attempts and social-engineering threats that technology alone may miss.

As a result, suppliers move from assumption to insight. They understand where risk lies and can prioritise remediation effectively.

2. Respond

A written response plan is valuable only if it works under pressure. Alignment with this pillar means suppliers improve response capability through live data and practice.

Penetration testing and SOC-driven monitoring provide actionable intelligence. These findings inform incident response playbooks, highlighting where escalation or detection may fail. Moreover, simulated exercises and BCDR tabletop scenarios ensure procedures are tested and refined.

Consequently, organisations respond faster, communicate more effectively, and minimise impact when incidents occur.

3. Reinforce

Resilience depends on strong, validated controls. Achieving Cyber Essentials Plus, ISO 27001, DSPT, and ITHC provides structure, but reinforcement ensures they remain effective over time.

Continuous vulnerability scanning, retesting after remediation, and proactive monitoring from a 24/7 SOC verify that controls operate correctly. In addition, regular consultancy reviews identify configuration drift or emerging risks before they become vulnerabilities.

Therefore, reinforcement is ongoing rather than periodic, embedding a culture of continuous improvement across technical and procedural layers.

4. Reflect & Recover

The final pillar focuses on continuity. When disruption happens, recovery must be swift, coordinated, and informed by experience.

ISO 27001-aligned Business Continuity and Disaster Recovery (BCDR) planning provides the framework. However, effective recovery also depends on insight gained from testing, monitoring, and training. Lessons from penetration testing feed directly into future rehearsals. Likewise, SOC data helps identify root causes and refine defensive strategies.

In turn, suppliers can prove to NHS buyers that recovery is operational, measurable, and continually improving.

A case in point: Epro

Epro, a digital healthcare supplier supporting more than 60,000 NHS users across 11 trusts, faced the challenge of demonstrating resilience rather than just compliance.

Working with Assure Technical, Epro aligned its approach to the Four Pillars:

• Recognise – Annual CREST-approved penetration testing and regular vulnerability assessments exposed risks overlooked by standard audits.
• Respond – Test results shaped incident-response planning and informed staff awareness sessions.
• Reinforce – Achieving Cyber Essentials Plus and aligning with ISO 27001, DSPT, and ITHC validated their controls and ensured continual assurance.
• Reflect & Recover – Consultant-led support embedded BCDR practices and built confidence that recovery was practical, not theoretical.

As a result, Epro reduced internal workload, improved resilience, and strengthened its reputation as a trusted NHS partner.

Why suppliers must act now

The NHS Four Pillars are reshaping expectations. Suppliers that demonstrate alignment will strengthen trust, protect contracts, and position themselves competitively.

Conversely, failing to evidence resilience risks exclusion from frameworks and potential reputational harm.

Next steps for suppliers

Achieving alignment demands a combination of technology, governance, and culture.

Assure Technical supports suppliers with:

• CREST-approved Penetration Testing and Vulnerability Scanning
• 24/7 Security Operations Centre (SOC) monitoring and rapid response
• Cyber Awareness Training tailored for healthcare teams
• Compliance and Certification Support for DSPT, ISO 27001, Cyber Essentials Plus, and ITHC
