Improving Internet of Medical Things (IoMT) Cybersecurity

Improving Internet of Medical Things (IoMT) Cybersecurity

From small, independent practitioners to large, integrated health systems, cyberattacks on healthcare records, IT systems and medical devices have infected even the most protected systems.

Why is it Important to Protect Healthcare Systems from Cyberattacks?

Faced with pandemic challenges and increasing ransomware attacks, healthcare delivery organizations (HDOs) are under pressure to adapt to changing medical priorities plus improve cybersecurity.

However, securing IoMT (Internet of Medical Things) devices and building management systems is not an easy task. Challenges include:

  • Protecting healthcare delivery from costly and dangerous ransomware attacks to ensure patient care and safety
  • Reducing IoMT and building management systems risks
  • Ensuring compliance with quickly changing government regulations and legislation
  • Gaining visibility to new and existing IoT, OT and IT assets, including high volumes of connected medical devices
  • Responding quickly and effectively to IoT/OT security incidents

To ensure continuous and safe care, and improve risk mitigation, healthcare providers need to close IoMT/OT blind spots and security gaps.

You Can’t Protect What You Can’t See

Good security starts with great visibility. Nozomi Networks is your partner for IoMT and OT visibility and cybersecurity solutions for smart hospitals and healthcare facilities.

As hospitals integrate a growing number of IoMT, IT and OT devices into their healthcare and facility systems, cybersecurity becomes more challenging.

The first step to improving the cybersecurity posture of your organization is being able to see all the devices and networks in your facilities.

The Nozomi Networks solution provides automated asset inventory that allows you to see your entire healthcare ecosystem and its risks in one place to keep your systems running and ensure patient safety.

This includes patient diagnostic and monitoring systems, network connected medical devices, IoT devices, and building systems, such as elevators, HVAC and power distribution that keep a facility functioning.

In addition, Nozomi Networks improves your situational awareness by creating a live interactive network visualization for a real-time view of your hospital’s many devices and networks. This shows assets, links, traffic, data flows and more—quickly becoming an indispensable monitoring tool.

Visibility drives confidence. A clear view of your IoMT and building management systems is fundamental to improving cyber risk management across your healthcare facilities.

Secure Your Systems and Protect Healthcare

Keeping patients safe and maintaining healthcare delivery is fundamental. Yet modern hospital systems are vulnerable to cyber threats and downtime risks.

A hospital’s complex and diverse systems provide a large attack surface for threats, especially as more IoMT, IT and OT devices are added. With the rise in ransomware and sophisticated cyberattacks, it’s imperative that facilities anticipate and quickly diagnose and respond to threats.

The Nozomi Networks solution detects malware and IOCs by combining multiple types of OT/IoT/IT threat detection and by receiving continuously updated threat and asset intelligence. It helps you respond efficiently to IoMT/OT incidents with correlated alerts and actionable intelligence that lead to swift remediation.

Our solution rapidly and passively detects vulnerabilities across a wide range of devices, networks and vendors. Its dashboards and reports help you efficiently prioritize and address risks.

Nozomi Networks helps you prevent or minimize security breaches and ransomware attacks, reduces patient and healthcare risk, and improves your cybersecurity and operational resilience.


Given the rise in ransomware attacks on healthcare and nation-state attacks on medical research facilities, healthcare entities should treat network compromises with the utmost priority, comparable to healthcare emergencies.

Expand Your Cybersecurity Strategy

Healthcare networks may be monitored by IT cybersecurity tools and programs today, but if existing and newly added IoMT and OT devices are not adequately covered, they are exposed to cyber risk.

To limit cyber and healthcare risk, healthcare providers need a comprehensive cybersecurity strategy that covers not just traditional IT systems but expanding IoMT and building management systems infrastructure.

The right IoMT/OT solution helps future-proof your facilities with continuous threat intelligence to counter tomorrow’s malware and scalability to handle new technology and properties.

Scale Up

Dispersed facilities and quickly evolving IoMT systems require monitoring at scale. It’s critical to implement a solution that can protect any number of IoMT, OT, IT, edge and cloud assets.

You need an easy-to-deploy and resource-efficient system that scales readily. A SaaS-powered application provides a single pane of glass view of aggregated and prioritized risks across all facilities. It scales quickly and reduces complexity and cost. Paired with a wide range of on-site sensors, such a system meets the needs of any type of healthcare organization.

The Nozomi Networks solution scales smoothly and is easily tailored to meet your needs. It allows you to monitor very high numbers of assets and facilities in a cost- and resource- efficient way.

The Connected Healthcare Experience

In today’s smart hospitals, every step of a patient’s journey involves connected technology that improves healthcare, comfort and safety.

The IoMT and building automation systems that deliver this experience are critical and need to be secured to protect patients and healthcare delivery.

Easy to Deploy IoMT/OT Security

The Nozomi Networks solution easily integrates with your existing hospital or healthcare infrastructure to improve cyber and operational resilience.

The sample deployment approach shown is readily tailored to meet your needs using a flexible architecture, an extensive range of sensors and integrations with other systems.

Flexible, Scalable Deployment

The Nozomi Networks solution readily scales to monitor hundreds of locations and thousands of assets from a central location, so you can efficiently secure your changing devices, systems and presence.

The scalability approach shown is easily tailored to meet your needs using a flexible architecture, an extensive range of sensors and integrations with other systems.
