Why the next cybersecurity conversation in healthcare is not about data. It is about whether care can continue.
For years, healthcare cybersecurity has largely been discussed as a data protection problem.
Protect patient records. Secure personal information. Meet regulatory requirements. Prevent breaches.
All remain essential. But they no longer capture the scale of the risk.
Healthcare has become extraordinarily dependent on connected digital infrastructure. Electronic health records, diagnostic platforms, imaging systems, laboratories, pharmacies, connected medical devices, cloud services, communications networks and third-party platforms now form part of the machinery through which modern healthcare is delivered.
That changes the cybersecurity question.
What happens when a cyberattack does not simply expose information, but interrupts the ability to deliver care?
From information security to operational resilience
A compromised database is serious.
A hospital unable to access clinical systems, process diagnostic information, communicate effectively or use critical applications presents an entirely different category of risk.
This is why ransomware remains particularly dangerous for healthcare organisations. The attacker does not necessarily need to compromise every system. Disrupting a sufficiently important part of an interconnected clinical environment can create consequences far beyond the original point of intrusion.
The data reflects that pressure.
ENISA’s analysis of health-related incidents found that ransomware accounted for 45% of incidents analysed in its 2024 threat landscape, while data breaches represented another 28%. Healthcare has also been among Europe’s most affected critical sectors.
Meanwhile, Verizon’s 2025 Data Breach Investigations Report found that system intrusion, a category that includes ransomware, overtook miscellaneous errors as the leading breach pattern within healthcare. Across industries, the report also recorded a 34% increase in vulnerability exploitation and found that third-party involvement in breaches had doubled.
The implication is important.
Healthcare organisations are not defending a perimeter anymore. They are defending an ecosystem.
The attack surface has moved
