Hospitals and health systems are rapidly becoming high-risk targets for cyberattacks because of the explosion of connected medical devices on their networks.

In 2025, modern hospitals operate with dozens of connected technologies per patient bed — from MRI scanners and infusion pumps to networked tablets and monitoring systems. That means large hospital systems may manage tens of thousands of devices. Every single one of those devices is a potential weakness if not properly secured and monitored.
And things are worse than most people realize. A Cybernews survey notes that 93% of major healthcare organizations experienced common cyberattacks in the past 12 months alone. This rising tide of attacks reflects broader industry trends showing healthcare remains among the most targeted sectors for ransomware, data theft, and medical device exploitation.
Why Device Vulnerability Is a Critical Problem
One of the core issues facing hospital security teams is lack of visibility into connected devices. Forty-three percent of hospital CISOs said that complete device visibility was their most pressing challenge. In many cases, IT departments do not even know which devices are connected to the network — let alone where they are or how secure they might be.
This gap creates blind spots attackers can exploit. Hospitals often mix specialized medical gear with everyday devices, like Bluetooth speakers or personal tablets, all of which can connect to internal networks without cybersecurity oversight.
External research corroborates these risks. Reports find that more than half of medical devices in hospitals have critical vulnerabilities, and 53% of internet-connected medical devices analyzed had known security flaws. These vulnerabilities can compromise patient data, disrupt clinical operations, and — in the worst cases — directly affect treatment delivery.
Organizational Failures Amplify Cyber Risk
Security challenges are not just technical — they are organizational. A substantial number of hospital security leaders blame unclear ownership and fragmented responsibilities for widening the attack surface. According to the Cybernews article, many medical devices are deployed or modified by clinical teams, biomedical engineers, or third-party technicians without notifying IT security.
That means security teams often only learn about a device after it is already on the network. This lack of coordination makes it nearly impossible to enforce consistent cybersecurity policies, patch known vulnerabilities, or apply threat detection tools uniformly across environments.
Across the healthcare sector, surveys have repeatedly shown that hospitals spend less than 4% of IT budgets on medical device security, and many lack even basic inventories of connected equipment. Without solid asset tracking and risk ownership, hospitals are forced to respond to threats instead of preventing them.
The Limits of Traditional Detect and Respond
Many organizations still depend on detect and respond security models, such as antivirus, endpoint detection and response (EDR), and SIEM analytics. But when hospitals don’t even know which devices are connected — or where they live on the network — detection tools often miss threats until it’s too late.
For example, ransomware detection is only effective when all devices are visible and accounted for. Yet, as the Cybernews piece notes, detection priorities often stem from visibility problems itself.
This reality shows why traditional reactive cybersecurity fails in environments with thousands of unmanaged endpoints spread across IT, IoT, IoMT (Internet of Medical Things), and OT systems. Once attackers gain a foothold, lateral movement and deep network access can occur undetected. Patient data, imaging results, and critical system controls are suddenly ripe for compromise.
A Better Approach: Isolation and Containment
To truly defend modern hospital networks, especially those supporting clinical care, organizations need to shift from detect and respond to isolation and containment. This means limiting what code can run where and preventing unauthorized execution and lateral movement outright.
That is where AppGuard shines. With more than a decade of proven endpoint protection success, AppGuard does not depend on detection signatures or post-compromise alerts. Instead, it isolates critical systems, restricts unexpected behaviors, and contains threats at their source before they can spread. AppGuard protects endpoints — including workstations, servers, and networked devices — without heavy performance overhead or complex management.
Healthcare organizations that adopt this approach can:
-
Block unknown and unauthorized threats before execution. Isolation prevents malware from ever running its harmful code.
-
Stop lateral movement. When attackers try to move between devices or escalate privileges, containment boundaries prevent compromise propagation.
-
Protect unmanaged and legacy systems. AppGuard’s model supports hardened defense for devices that cannot easily be patched or where deep visibility is limited.
Endpoint protection built on isolation and containment changes the equation from reactive to preventative.
Conclusion: Act Before Your Hospital Is the Next Headline
Hospitals are at the forefront of digital transformation, but that progress brings serious cyber risk. Connected medical devices offer attackers multiple entry points, and lack of visibility and accountability means threats can go unnoticed until damage is done.
Healthcare cyber incidents are real, costly, and potentially life threatening. It is time for business owners and security leaders to think differently. The old paradigm of detect and respond is no longer enough.
