A hospital’s most critical equipment, infusion pumps, ventilators, insulin pumps, MRI machines, used to live in a world of its own, disconnected from broader networks and largely invisible to hackers. That world no longer exists. Today’s medical devices are networked, software-driven, and increasingly exposed to the same threats that target banks, retailers, and government agencies. The difference is that when one of these systems fails, the consequence isn’t a data breach headline, it’s a delayed surgery, a stalled infusion pump, or worse.
The Numbers Tell the Story
The 2026 Medical Device Cybersecurity Index surveyed 551 healthcare professionals. Respondents came from the US, UK, and Germany.
Nearly a quarter of healthcare organizations reported a cyberattack or exploited vulnerability linked to a medical device. Four out of five of these incidents caused meaningful disruption to patient care.
The impact is far from abstract. It can lead to delayed imaging and postponed procedures. It can also create gaps in critical care delivery.
The scale of unresolved risk is just as troubling. The same research found that more than a quarter of organizations run devices past their manufacturer’s end-of-support date.
Nearly half also acknowledge using equipment with known, unpatched vulnerabilities. This echoes older findings from an FBI report. The report found that more than half of connected medical and IoT devices had at least one unpatched critical vulnerability.
Industry analysts say the problem remains largely unresolved years later. This highlights the ongoing security risks facing connected healthcare devices.
Perhaps most alarming, the human cost of these incidents is becoming measurable rather than theoretical. A separate study, referenced in recent industry coverage, found that in-hospital mortality rose by roughly a third during ransomware incidents, a statistic that reframes medical device cybersecurity as a clinical safety issue rather than a purely technical one.
Why Devices Are So Hard to Secure
Several structural problems make medical devices uniquely difficult to protect.
Long lifecycles, slow patching. Unlike a laptop or phone, medical equipment is expected to last a decade or more. Replacing an MRI machine or a fleet of infusion pumps isn’t driven by security concerns; it’s driven by capital budgets and clinical need. Industry research has found that it takes roughly three years on average from the time a device is purchased to when vulnerabilities in its components are even disclosed, a gap that leaves hospitals operating blind for long stretches.
Downtime is dangerous. Applying a firmware patch to a hospital device isn’t as simple as a routine software update. Taking equipment offline, even briefly, can itself create clinical risk, meaning IT and security teams must weigh cybersecurity benefits against the possibility of interrupting care.
The rise of the Internet of Medical Things (IoMT) means more devices are now networked. Each connected device can become a potential entry point for attackers.
AI-enabled devices add another layer of risk. A 2026 research study flagged vulnerabilities in AI-enabled and AI-assisted medical devices. It also highlighted another concern. AI models could be used to develop exploits targeting healthcare organizations.
More than half of the surveyed organizations already use AI-enabled or AI-assisted medical technologies. This means the risk is not hypothetical. It is already part of current healthcare deployments.
Regulators and Buyers Are Responding
The good news is that medical device cybersecurity is no longer an afterthought in purchasing decisions. The 2026 Index found that the vast majority of organizations now include cybersecurity requirements in their procurement processes, and more than half have rejected a device outright over cybersecurity concerns, a notable jump from the year before.
Regulatory pressure is accelerating this shift. FDA cybersecurity guidance and the EU’s Medical Device Regulation are shaping global manufacturing standards.
New EU Cyber Resilience Act requirements will also take effect in September 2026. These rules include new obligations around vulnerability reporting. They will affect manufacturers selling products in the European market.
Companies must align their vulnerability disclosure practices with both US and EU frameworks. Otherwise, they could face challenges when selling in either market.
What This Means Going Forward
The direction of travel is clear. Medical device cybersecurity is shifting from a compliance checkbox to a core patient safety requirement. It is becoming as important as sterilization standards or dosage accuracy.
Hospitals are getting better at scrutinising what they buy. However, procurement improvements alone cannot secure legacy devices already installed in ICUs, emergency departments, and operating rooms.
Closing this gap will require action from all sides. Manufacturers must build security into devices from the design stage. Hospitals need to invest in ongoing monitoring and patch management. Regulators must also keep tightening the standards that govern which devices can enter the market.
For patients, the stakes could not be more concrete. A compromised device isn’t just an IT incident, it’s a direct threat to the quality and continuity of care. As connected medical technology continues to expand, treating cybersecurity as a secondary concern is no longer an option healthcare organizations can afford.
