How To Choose The Right IoMT Security Vendor

Last updated: April 2026

The Internet of Medical Things (IoMT) market continues to expand rapidly. Over seven million IoMT devices are projected to be deployed in smart hospitals by 2026, more than double the number in 2021. The average hospital now houses between 10 and 15 connected medical devices per bed, and in large health systems, that can mean upwards of 350,000 IoMT devices across a single organization.

That growth has made IoMT a primary target for attackers. Healthcare-related ransomware attacks grew 30% in 2025, with 293 attacks recorded against hospitals and direct care providers. Research across 2.25 million IoMT devices found that medical devices average 6.2 vulnerabilities per device and that 99% of hospitals manage at least one IoMT device with a known exploited vulnerability. Meanwhile, 60% of medical devices in active use are end-of-life with no available security patches.

Conventional IT security tools were not built for these devices. IoMT equipment runs proprietary firmware, communicates over clinical protocols, cannot host security agents, and often cannot be taken offline for patching without affecting patient care. Securing these devices requires a purpose-built approach, and the vendor you choose determines whether that approach actually works in your environment.

This article covers why IoMT matters to your organization, what capabilities separate effective IoMT security platforms from inadequate ones, and how to evaluate vendors against the realities of a healthcare environment.

Why IoMT Devices Matter to Your Hospital

Connected medical devices deliver measurable value across healthcare operations. Understanding that value provides important context for evaluating security investments. The goal of IoMT security is to protect these benefits without slowing them down.

Improved clinical outcomes. IoMT devices provide real-time patient data, from continuous vital sign monitoring through infusion pump telemetry to imaging system integration with electronic health records. Clinicians make better-informed treatment decisions when they have access to accurate, timely device data. Remote patient monitoring extends care beyond the hospital walls, improving outcomes for chronic conditions while reducing readmissions.

Operational efficiency. Connected devices automate data collection that previously required manual effort, freeing clinical staff to focus on direct patient care. Asset tracking systems reduce the time nurses spend locating equipment. Automated dispensing systems improve medication accuracy while reducing pharmacy workload.

Cost reduction. Higher device utilization, fewer manual workflows, and reduced adverse events translate to lower operating costs. Organizations that understand which devices are actually in use (and which sit idle) can make smarter procurement decisions and avoid unnecessary capital expenditure.

Regulatory compliance. Connected devices that generate audit trails, report utilization data, and integrate with compliance platforms help organizations meet HIPAA requirements, respond to FDA safety communications, and satisfy the growing number of state-level cybersecurity mandates like New York’s 10 NYCRR 405.46 and the Texas HHSC directive.

Recruitment and reputation. Healthcare professionals increasingly expect to work with current technology. Organizations known for investing in connected clinical infrastructure attract stronger clinical talent and build patient trust.

Protecting these benefits means choosing an IoMT security vendor that understands clinical workflows, device constraints, and the regulatory environment your organization operates within.

6 Capabilities to Evaluate When Choosing an IoMT Security Vendor

Not every IoMT security platform delivers the same depth of coverage. The following six capabilities are what separate vendors that work in production healthcare environments from those that work only in demos.

1. Pre-Purchase Security Assessment

The most cost-effective time to address IoMT risk is before a device ever touches your network. Evaluating a device’s security posture during procurement allows your organization to negotiate with manufacturers, set configuration requirements, and avoid introducing known vulnerabilities into your environment.

An effective pre-purchase capability should provide a comprehensive risk profile for the device, including known vulnerabilities, manufacturer patching history, end-of-life projections, and recommended secure configuration settings. It should also evaluate the device against your existing network architecture to identify potential risks specific to your environment.

Asimily’s ProSecure database maintains security profiles across a wide range of medical and laboratory devices. The platform generates a detailed risk assessment before procurement, including configuration recommendations and risk modeling that shows how the device would affect your organization’s overall security posture. This means your security team has data to bring to procurement conversations rather than discovering problems after deployment.

2. Passive, Safe Device Discovery and Inventory

Accurate inventory is the foundation of every other IoMT security function. You cannot prioritize vulnerabilities, write segmentation policies, or detect anomalies for devices you do not know are on your network.

In clinical environments, discovery must be passive. Active vulnerability scanning has been documented to disrupt medical devices, including devices actively involved in patient care. An infusion pump that crashes during a scan is not a hypothetical risk; it is a patient safety event.

Look for vendors that use passive deep packet inspection to identify and classify IoMT devices based on their network traffic, without sending any packets to the devices themselves. The inventory should capture manufacturer, model, firmware version, operating system, communication patterns, network neighbors, and clinical department assignment.

Asimily’s passive discovery covers IoMT, IoT, IT, and OT devices from a single platform. The protocol analyzer handles clinical protocols alongside standard IT traffic, and new device types can be classified through rapid protocol analysis without waiting for a product release cycle. The platform also tracks device utilization data, giving biomedical engineering and clinical technology teams insight into how devices are actually being used, not just where they are.

3. Contextual Vulnerability Prioritization

A large health system might have tens of thousands of IoMT devices carrying hundreds of thousands of CVEs. Treating every vulnerability equally buries the security team in work that does not meaningfully reduce risk to patient care or data.

Raw CVSS scores are insufficient for IoMT. A critical CVSS score on a device that sits on an isolated clinical VLAN with no known public exploit carries far less real risk than a medium-severity vulnerability on an internet-reachable imaging system with a published proof-of-concept.

Effective IoMT vulnerability management requires contextual analysis that factors in the device’s network position, whether a known exploit exists in the wild, the device’s clinical function and patient safety implications, and what compensating controls are already in place.

Asimily combines analysis from Asimily Labs with AI/ML-based techniques and the MITRE ATT&CK framework for actual attack path analysis. Rather than using MITRE ATT&CK only for classification, the platform determines whether a vulnerability on a specific device in a specific network context is realistically exploitable. This approach can reduce the list of devices requiring immediate action by an order of magnitude, allowing security and biomed teams to focus remediation where it reduces the most clinical risk.

4. Prescriptive, Actionable Remediation

Identifying vulnerabilities is only useful if your team can act on the findings. Many IoMT security platforms stop at detection, leaving security teams with a list of problems but no guidance on how to fix them within the operational constraints of a healthcare environment.

Evaluate whether the vendor provides specific remediation instructions for each vulnerability, not generic recommendations. In IoMT, the most efficient fix is often not a firmware patch (which may require vendor coordination, clinical validation, and a maintenance window that is weeks away). It might be disabling an unnecessary service, restricting a network port, or applying a targeted segmentation policy that blocks the specific attack path without affecting the device’s clinical function.

Asimily prescribes the most efficient mitigation strategy for each vulnerable device and provides detailed implementation instructions. The platform’s remediation recommendations are ranked by effort and impact, so a team with limited time can apply the highest-value fixes first. Targeted segmentation groups devices by exploit vector using the MITRE ATT&CK framework, allowing risk reduction across thousands of devices within days rather than the months that device-by-device microsegmentation typically requires.

5. Network Segmentation That Works in Clinical Environments

Network segmentation is one of the most effective controls for IoMT environments, but traditional segmentation approaches frequently stall in healthcare settings. The reason: writing granular policies for thousands of heterogeneous medical devices, each with different communication requirements, is a project that overwhelms most teams before it delivers results.

Clinical devices have communication patterns that are more complex and more sensitive to disruption than typical IT endpoints. An imaging system that communicates with PACS, a vendor update server, and the clinical workstations in three different departments requires a policy that permits all of those connections while blocking everything else. Get it wrong, and you disrupt patient care.

Look for vendors that generate segmentation policies automatically based on observed device behavior, allow policy simulation before enforcement, and integrate with your existing NAC and firewall infrastructure rather than requiring new hardware.

Asimily’s Smart Policy Management creates segmentation policies informed by the platform’s deep device inventory and behavioral baselines. The Policy Simulation feature lets teams preview policy effects before deployment, reducing the risk of clinical disruption. Policies are enforced through existing infrastructure, including Cisco ISE and other NAC platforms, firewalls, and switch infrastructure.

6. Incident Response and Forensic Analysis

When a security incident occurs in a clinical environment, the response has constraints that other industries do not. A compromised medical device may be actively involved in patient care. Pulling it offline without understanding the clinical context could cause more harm than the security event itself.

Your IoMT security vendor should provide incident responders with the device context they need to make safe containment decisions: what the device is, what it does, who uses it, what it communicates with, and what clinical workflows depend on it. Packet capture on detection events gives responders the raw data needed for forensic analysis and root cause determination.

Asimily captures network traffic to and from flagged devices, provides a complete communication history for incident investigation, and supports device quarantine at the network level. Responders can trace the origin and scope of malicious activity across the IoMT environment, determine which other devices may be affected, and make informed containment decisions that balance security with patient safety.

Selecting the Right IoMT Security Vendor

The IoMT security market includes vendors with very different approaches to the problem. Some focus on device inventory and visibility. Others emphasize threat detection. A few address the full lifecycle from pre-purchase assessment through operational monitoring, vulnerability management, segmentation, and incident response.

When evaluating vendors, request a proof-of-concept in your actual clinical environment. Key questions to answer during evaluation: What percentage of your IoMT devices does the platform discover and correctly classify, including niche laboratory and clinical devices? How does it handle devices it has not seen before? Can it provide a pre-purchase risk assessment for devices you are considering acquiring? Does it prescribe specific, actionable remediation steps or just flag problems? Can it generate and simulate segmentation policies you trust enough to enforce in a clinical network?

Asimily addresses the full IoMT security lifecycle on a single platform: pre-purchase risk assessment through ProSecure, passive device discovery and inventory, MITRE ATT&CK-based vulnerability prioritization, prescriptive remediation, automated segmentation policy generation with simulation, continuous behavioral monitoring, and forensic packet capture for incident response.
