How boards can close the gaps that leave hospitals vulnerable to attack

Despite increasing awareness of cyber risks in the healthcare sector, smaller and public hospitals in South Africa often fail to recognize the full extent of the threat. This oversight creates a dangerous paradox: they remain both highly vulnerable and highly attractive targets for attackers.

Cyber risk today extends far beyond IT — it threatens the continuity of operations, the trust of stakeholders, regulatory compliance, financial sustainability, and ultimately patient safety. Unless boards and executives recognise cybersecurity as a strategic governance issue — and act with urgency to strengthen resilience through practical, affordable measures — the sector will remain dangerously exposed.

At Nexus Advisory, we have observed five interconnected factors that explain why many private and public healthcare providers remain reluctant to invest adequately in cyber resilience. These challenges are not just technical shortcomings — they reflect deeper issues of governance, prioritisation, and risk awareness at the executive level.

Unless these challenges are addressed, hospitals will continue to face an escalating exposure to cyber threats, with consequences that extend far beyond IT into operations, reputation, compliance, and ultimately patient safety:

Resource Constraints

• Budget pressures: With already stretched budgets and underfunded infrastructure, cybersecurity is too often dismissed as a “luxury” instead of a necessity.
• IT staffing gaps: Smaller hospitals typically rely on generalist IT staff, leaving no capacity for proactive monitoring or rapid incident response.

Perception of Risk

• “It won’t happen to us”: Leaders assume attackers target larger institutions, when in fact smaller hospitals are viewed as softer targets.
• Focus on physical over digital safety: Patient safety is often equated only with clinical or physical risks, ignoring the reality that cyberattacks can disable lab systems, radiology equipment, or patient records overnight.

Systemic Weaknesses

• Outdated systems: Legacy platforms and poor patching practices make hospitals easy prey.
• Weak governance: Cybersecurity frameworks (ISO 27001, NIST, etc.) are rarely embedded in hospital oversight.
• Fragmentation: Smaller facilities are often isolated from provincial or national cyber strategies.

Cultural and Political Factors

• Compliance-driven: Controls are applied to tick boxes, not to reduce real risk.
• Low executive awareness: Leadership often treats cybersecurity as “IT’s problem” instead of a patient safety and reputational risk.
• Short-term priorities: Investment is deferred in favour of urgent, visible needs such as equipment repairs or clinical staff hires.

Ransomware-Specific Risks

• High exposure: Hospitals’ dependency on uninterrupted access to patient data makes them prime targets.
• Low resilience: Without proper backups or tested recovery plans, an attack can cripple a facility for weeks.
• Insurance gaps: Many healthcare service providers are under-insured, leaving them unable to fund recovery.

Boards and healthcare executives that underestimate cyber threats are placing their institutions, staff, and patients at unacceptable risk. By recognising cybersecurity as a governance and strategic priority — and by committing to affordable, practical safeguards — leaders can strengthen resilience before an attack strikes, not after.

Effective cybersecurity is a matter of leadership, not technology alone. At Nexus Advisory, we partner with healthcare leaders to assess cyber risks and design pragmatic, resource-aware strategies that build lasting resilience.
