Cybersecurity for Healthcare: Protecting Patient Data
Healthcare is one of the most targeted sectors for cyberattacks. You handle sensitive patient data, often rely on older systems, and can't afford downtime. Here's what healthcare organizations need to know about cybersecurity.
Why Healthcare Is Heavily Targeted
Healthcare organizations face unique cyber risks:
Valuable data
Medical records sell for 10-50x more than credit cards on dark web
Life-critical systems
Attackers know you'll pay to restore operations quickly
Complex environments
Mix of old and new systems, many connected devices
Limited IT resources
Often understaffed IT departments relative to risk
24/7 operations
Downtime directly impacts patient care
Regulatory pressure
GDPR + NIS2 + sector-specific requirements
What this looked like for one practice, September 2026
A GP practice in Gouda, in the Netherlands, had patient files stolen. Huisartsencentrum Klein Iterson said people who should not have had access reached part of its systems. Names, dates of birth, addresses, phone numbers and parts of medical files were taken. For some patients, so was the Dutch BSN. That is the same kind of number as the Belgian rijksregisternummer, and it is hard to change and useful for identity fraud for years.
This was a GP practice. Not a hospital with its own security team, and not the kind of organisation most breach stories are about. If you keep other people's medical records with a handful of staff and one shared system, that practice looks a lot like yours. LockBit 5.0 claimed the attack and had already published stolen documents. How the attackers got in was never made public, and the practice said it still did not know how much had been taken.
So: if someone logged into your system tomorrow who had no business being there, would you find out?
NIS2 Classification for Healthcare
Under the NIS2 directive , most healthcare activities sit in a high-criticality sector (Annex I). Whether you are an essential or an important entity depends on your size as well as your sector. For an essential entity this means:
- A periodic conformity assessment (voluntary for important entities)
- More rigorous supervision by authorities
- Higher potential fines for non-compliance
- Mandatory incident reporting (24-hour notification)
- For essential entities: CyFun Essential by default, unless their own risk assessment justifies a lower level they can show they meet by 18 April 2027
- Management held personally accountable
The CyberFundamentals framework helps healthcare organizations meet these requirements in a structured way. Review the different levels to determine which applies.
Being in the healthcare sector does not by itself make you an essential entity: size counts too, and a smaller practice may be an important entity or out of scope. An essential entity defaults to CyFun Essential, but may choose lower when its own risk assessment justifies it, at its own responsibility, and must show by 18 April 2027 that it meets that level. Our 2-minute NIS2 self-check gives a rough on-screen estimate for your healthcare activity: whether you are in NIS2 scope, as which entity, and which CyFun level the CCB risk model points to.

Security Priorities for Healthcare
Focus on these areas first:
1. Patient Data Protection
- Encrypt all patient records (at rest and in transit)
- Implement strict access controls (role-based)
- Audit who accesses what data
- Train staff on data handling
- Have clear data breach procedures
2. Medical Device Security
- Inventory all connected medical devices
- Segment medical devices on separate networks
- Apply patches where possible (coordinate with vendors)
- Monitor device behavior for anomalies
- Plan for devices that can't be patched
3. Ransomware Defense
- Maintain offline backups (tested regularly)
- Implement email security (phishing is #1 vector)
- Deploy endpoint detection and response (EDR)
- Practice incident response scenarios
- Have communication plans for patients/families
4. Availability & Continuity
- Define recovery time objectives for critical systems
- Test failover procedures
- Plan for manual operations during outages
- Coordinate with other healthcare facilities
- Keep paper backup procedures ready
Common Healthcare Challenges
Network segmentation, compensating controls, migration planning
Isolate on dedicated VLANs, monitor traffic, work with vendors on updates
Focus on workflow-friendly security, explain patient safety connection
Prioritize based on risk, use frameworks (CyberFundamentals) for structure
Rolling updates, redundant systems, scheduled maintenance windows
Incident Response for Healthcare
Healthcare incidents require special considerations. Ransomware attacks are particularly dangerous in healthcare due to the direct impact on patient care:

Frequently Asked Questions
Is my medical practice subject to NIS2?
If you are medium-sized or larger (50+ staff, or both turnover and balance sheet above €10 million, Recommendation 2003/361/EC), likely yes. Smaller practices may still be covered if they provide critical healthcare services. Check with the CCB for definitive classification.
What level of CyberFundamentals do healthcare organizations need?
It starts with your NIS2 class. An essential entity that uses CyFun defaults to CyFun Essential: a certificate by 18 April 2027, or an Important verification statement plus a plan to reach Essential by 18 April 2028. It may choose a lower level only when its own risk assessment justifies it, and must show by 18 April 2027 that it meets that level. That choice is its own responsibility, and the CCB inspection service can check it. An important entity had no administrative formality with the CCB by 18 April 2026, but must implement all NIS2 measures, and the CCB can ask for evidence, for example after an incident. It chooses its level using the CCB Selection Tool, which is a risk assessment. If it opts for a voluntary CyFun assessment, the Royal Decree sets at least the Important level (Art. 11). Confirm your class and level before scoping any work: confusing the two is the most common mistake we see.
How do we secure old medical devices?
Network segmentation is key - put legacy devices on isolated networks. Monitor their traffic, limit access, and work with vendors on update schedules. Document compensating controls for devices that can't be patched.
What happens if patient data is breached?
You must notify the Belgian DPA within 72 hours (GDPR), report to CCB within 24 hours (NIS2), and inform affected patients if there's high risk to them. Have procedures ready before an incident occurs.
How do we balance security with clinical workflows?
Involve clinical staff in security planning. Focus on solutions that don't impede patient care - single sign-on, badge access, mobile-friendly authentication. Explain that security protects patients, not just data.
