In healthcare, a cyberattack is not an IT outage; it's a patient-safety event
Connected medical devices, cloud EHR platforms, and a vast third-party ecosystem have made care delivery more capable, and more exposed. Healthcare is now the most-targeted critical infrastructure sector, where downtime is a patient-safety event. Most security providers cover enterprise IT. Kudelski Security covers IT and the connected medical devices attackers use to reach it.
Clinical environments now connect infusion pumps, imaging systems, and patient monitors to enterprise networks, cloud EHR platforms, and vendor portals. Many run legacy operating systems that cannot be patched on normal cycles or host security agents.
When ransomware enters this flat network, it does not stop at the IT boundary. It reaches the devices delivering care, and no IT recovery plan was designed for a compromised patient monitor.
Healthcare depends on deep integration with clearinghouses, billing processors, benefits administrators, and cloud EHR vendors. Each connection is a potential entry path, and a single upstream compromise can cascade nationwide.
The Change Healthcare attack halted claims and payment processing for roughly 70% of US pharmacies. At this scale, third-party risk cannot be managed through periodic questionnaires alone.
Ransomware that reaches clinical systems takes EHR, imaging, and monitoring offline.
Care is delayed, ambulances divert, and clinicians revert to paper. In healthcare, downtime is a patient-safety event.
Healthcare carries the highest breach cost of any industry: $7.42 million on average (IBM, 2025).
The Change Healthcare attack ultimately cost its parent company $3.1 billion. For thin-margin providers, one incident can threaten viability.
Health data combines financial identifiers, government IDs, clinical history, and biometrics, and unlike a credit card it cannot be reissued.
A 2026 breach at NYC Health + Hospitals exposed the fingerprints and palm prints of 1.8 million people. The exposure is permanent.
HIPAA, NIS2, and the proposed Security Rule overhaul are converging simultaneously.
A material incident triggers mandatory disclosure and investigation, often while the organization is still recovering clinically.
Healthcare organizations operating across the US and EU face overlapping mandatory obligations, tight reporting windows, and material penalties.
Most security providers extend IT tooling into OT as an afterthought. Kudelski Security covers both natively, from its 24/7 Cyber Fusion Centers, correlating IT and OT telemetry in a single detection model rather than running two disconnected practices. Our platform integrates the leading cyber-physical security technologies, so your existing OT investments feed our detection instead of being replaced. Detections are triaged by analysts who understand industrial ecosystems and process constraints, including when not to isolate a system.
When a control system goes down, response time is measured against lost service. Our 24/7 Cyber Incident Response Retainer provides guaranteed response capacity from the moment an incident is declared, with analysts already familiar with your environment. Every engagement runs with a named team that builds working knowledge of your sites, your process constraints, and your regulatory constraints.
Kudelski Security has been recognized seven consecutive times as a Representative Vendor in Gartner's Market Guide for DFIR Retainer Services (2019–2026).
Security spending in healthcare competes with clinical and operational investment, so the business case has to hold. A Forrester Total Economic Impact study of Kudelski Security's MDR service documented a 249% ROI and 68% faster detection and response, with breakeven in under six months.
Healthcare was hit by 460 ransomware attacks in 2025, more than any other critical infrastructure sector (FBI/AHA, 2026). Attackers target hospitals because downtime is a patient-safety event, which raises the pressure to pay quickly, and because clinical networks connect large numbers of unpatched connected medical devices to systems holding highly valuable patient data.
IoMT (Internet of Medical Things) security protects connected clinical devices such as infusion pumps, imaging systems, and patient monitors. Many run legacy operating systems that cannot be patched on normal cycles or host security agents, so when ransomware enters a flat hospital network it reaches the devices delivering care. Kudelski Security's MDR for OT extends detection and response to the IoMT estate.
Healthcare has the highest average breach cost of any industry at $7.42 million, and has held that position for 14 consecutive years (IBM, 2025). Costs escalate because health data combines financial identifiers, government IDs, and clinical history that cannot be reissued, and because incidents often force clinical downtime while the organization is still recovering.
US healthcare organizations must comply with the HIPAA Security Rule, with a proposed modernization that would make MFA, encryption, and asset inventories mandatory. In the EU, NIS2 classifies hospitals as essential entities with 24-hour early-warning and 72-hour reporting duties and penalties up to €10 million or 2% of turnover. The EU Cyber Resilience Act adds vulnerability-reporting duties for connected medical devices from September 2026.
Start with a complete inventory: discover, classify, and map every device, closing the asset-visibility gap that regulators and the proposed HIPAA rule specifically target. Then apply continuous monitoring tuned to clinical environments and network segmentation aligned to IEC 80001. Kudelski Security delivers medical-device asset and exposure management alongside 24/7 MDR built on the Claroty platform.
Ransomware that reaches clinical systems takes EHR, imaging, and monitoring offline. Care is delayed, ambulances divert, and clinicians revert to paper. The 2024 Change Healthcare attack halted claims and payment processing for roughly 70% of US pharmacies and ultimately cost its parent company $3.1 billion. In healthcare, downtime is a patient-safety event.
Safeguard patient data, secure your supply chain, and keep clinical systems online with Kudelski Security's tailored solutions.
