Interoperability vs. Security: FDA Priorities Explained
Interoperability vs Security in Medical Devices: FDA Requirements Comparison
The FDA treats interoperability and security as equally critical goals that manufacturers need to prioritize throughout a medical device’s lifecycle. To align with future FDA standards, it’s essential to understand what these terms mean and how they interplay.
What is Interoperability?
Interoperability, as defined by the FDA, refers to "the ability to safely, securely, and effectively exchange and use information among one or more devices, products, technologies, or systems" [6]. Think of a glucose monitor that shares readings with an insulin pump or a ventilator that sends data to a hospital’s electronic health record (EHR) system - these systems must not only communicate but also interpret and act on the data correctly.
To achieve this, manufacturers need to define clear functional, performance, and interface requirements. This includes standardizing units of measure, data formats, and communication protocols. The FDA relies on recognized standards like the AAMI/ANSI/UL 2800 series for interoperability and the ISO/IEEE 11073 series for device communication [6]. When implemented effectively, interoperability can reduce medical errors, enhance care coordination, and drive innovation across healthcare systems.
What is Security?
Security, or more specifically cybersecurity, is described by the FDA as "the process of ensuring medical devices are sufficiently resilient to cybersecurity threats, protecting against critical medical device security risks like unauthorized access and data manipulation" [8][2]. This applies to every stage of a device’s lifecycle - from design and development to post-market monitoring and eventual decommissioning.
In 2026, the FDA made significant updates by aligning cybersecurity requirements with the Quality System Management Regulation (QMSR) and ISO 13485 standards [2]. This change ensures that security is integrated into design controls, validation processes, and risk management frameworks, treating it as a core component of device quality. Manufacturers must now adopt practices like threat modeling, secure development processes, and continuous monitoring to address vulnerabilities proactively.
Here’s a quick comparison of the two priorities:
| Feature | Interoperability | Security (Cybersecurity) |
|---|---|---|
| Primary Goal | Enable data exchange and functional use across systems [6] | Protect devices and data from unauthorized access and threats [8] |
| Design Focus | Interface characteristics, units of measure, and data interpretation [3] | Resilience, vulnerability management, and threat mitigation [8][2] |
| Outcome | Improved care, reduced errors, and innovation [6] | Device safety, data integrity, and system resilience [2] |
| FDA Guidance | Design Considerations and Pre-market Submission Recommendations [7] | Cybersecurity in Medical Devices: Quality Management System Considerations (2025/2026) [8][2] |
Interoperability focuses on making devices work together seamlessly, while security ensures that these connections and the data they carry are protected from threats [6][2]. Addressing both is non-negotiable in today’s interconnected healthcare landscape. A device that excels in data exchange but falls short on security cannot fulfill its intended purpose under FDA guidelines. This balance is crucial to navigating the regulatory complexities discussed later.
FDA Cybersecurity Guidance: Core Requirements
The FDA's updated cybersecurity guidance, as of June 27, 2025 [8][9], lays out clear expectations for manufacturers to embed both interoperability and security into medical device designs. This update follows the Food and Drug Omnibus Reform Act (FDORA), signed on December 29, 2022, which granted the FDA explicit authority to demand cybersecurity information in medical device submissions. Under Section 524B, non-compliance is now classified as a prohibited act, potentially leading to criminal charges or legal action [10]. Cybersecurity is now treated as a critical component of quality management, aligning with the Quality System Management Regulation (QMSR) and ISO 13485 standards. Below, we break down the FDA's specific requirements for managing enterprise cybersecurity risks.
Risk Management Expectations
The FDA requires manufacturers to implement a Secure Product Development Framework (SPDF) designed to minimize vulnerabilities throughout a device's lifecycle [10]. This framework focuses on key areas like security risk management, architecture, and rigorous testing. Unlike traditional safety assessments that rely on historical data, the FDA emphasizes analyzing the exploitability of vulnerabilities rather than estimating the likelihood of incidents. As stated by the agency:
"Cybersecurity risks are difficult to predict and recognizes that it is not possible to assess and quantify the likelihood of an incident occurring based on historical data or modeling." [10]
Manufacturers are expected to assess devices within their broader system context and provide a Software Bill of Materials (SBOM) to ensure supply chain transparency. Utilizing automated vendor risk assessments can further streamline this transparency. For devices designed to work with other systems, this includes evaluating whether additional security measures are necessary for communication protocols like Bluetooth, Wi-Fi, or standard network layers [10]. Premarket submissions must include a Cybersecurity Risk Management Report and a Threat Model, documenting how security risks are systematically managed [10]. These steps aim to strike a balance between strong security and maintaining seamless data exchange capabilities. The next section explores the specific controls required for secure data sharing.
Security Controls for Data Sharing
For devices that share data with other systems, the FDA advises implementing controls to ensure that interoperability does not compromise security. These controls are essential for maintaining the integrity of data exchanges in interoperable systems. Examples include encryption, authentication mechanisms, and error-handling measures to protect data integrity [10]. The FDA underscores this point:
"Properly implemented cybersecurity controls will help ensure the safe and effective exchange and use of information." [10]
Automated security testing is also recommended to identify and address vulnerabilities early in the development process. Furthermore, manufacturers must document all cybersecurity risks and controls related to interoperable interfaces, including those connecting to healthcare systems or general-purpose computing platforms [10]. Devices equipped with wireless features or hardware connectors like USB or Ethernet - even if not directly connected to the internet - are classified as "cyber devices" and must address potential threats. Additionally, manufacturers are required to create a postmarket plan to monitor, identify, and address vulnerabilities as they arise [10].
Trade-offs Between Interoperability and Security
Medical device manufacturers are navigating a tough balancing act: creating devices that seamlessly share patient data while ensuring those same devices remain secure from cyber threats. The FDA's stringent cybersecurity requirements emphasize that both interoperability and security are critical for device quality and patient safety. This dual focus is particularly important in environments like hospitals, where a typical 300-bed facility generates around 1.37 TB of data daily, with medical devices accounting for 5%–11% of connected endpoints [11].
Interoperability plays a key role in modern healthcare. It allows devices to exchange data effortlessly, enabling faster clinical decisions, reducing manual errors, and providing access to diverse datasets that improve diagnoses [6]. However, every connection point also creates an opening for potential cyberattacks. As Phil Englert, Director of Medical Device Security at Health-ISAC, puts it:
"Cybersecurity engineering is about preventing devices from doing tasks you don't want or expect" [11].
The regulatory landscape has evolved significantly. Under current FDA standards, a device that offers excellent data-sharing capabilities but lacks robust security features is considered to have failed its intended purpose. This shift underscores the importance of addressing both aspects - interoperability and security - equally.
Benefits and Challenges: A Side-by-Side Look
| Priority | Primary Benefits | Key Challenges |
|---|---|---|
| Interoperability | Faster clinical decisions, fewer manual errors, improved patient outcomes, and access to diverse datasets for better diagnoses [6]. | Increased connectivity expands the attack surface, risks of data corruption or interception, and challenges in meeting varied communication standards like ISO/IEEE 11073 [6]. |
| Security | Stronger data protection, prevention of unauthorized access, and assurance of device reliability and confidentiality [11]. | Potential delays in urgent care due to authentication protocols, stricter documentation needs (like SBOMs), and costly redesigns of older systems [2][11]. |
The path forward is clear: manufacturers must integrate interoperability and security considerations from the very start of the design process. Security can no longer be treated as an afterthought. Instead, it must be woven into risk management strategies that align with existing regulatory frameworks [2]. This proactive approach is essential for achieving secure, efficient data-sharing without compromising patient safety.
How to Balance Interoperability and Security
To effectively balance interoperability and security, it's essential to incorporate cybersecurity into your quality management system right from the start. The FDA emphasized this on February 4, 2026, when it reissued its final cybersecurity guidance, aligning it with the updated Quality System Management Regulation (QMSR) and ISO 13485 standards [5]. George Strom, Business Development Director of IoT at Intertek, highlighted this approach:
"Those who integrate cybersecurity into their quality culture rather than treating it as a regulatory checkbox will be best positioned to meet regulatory expectations" [2].
For manufacturers, this means embedding cybersecurity into design controls (ISO 13485 Clause 7.3) and risk management (ISO 13485 Clause 7.1), alongside clinical safety measures. This strategy aligns with earlier FDA recommendations to integrate cybersecurity throughout the entire device development process.
FDA-Recommended Risk Management Frameworks
To complement integrated cybersecurity efforts, the FDA supports structured frameworks for managing risks effectively. One such framework is the Secure Product Development Framework (SPDF), derived from IEC 81001-5-1. It provides a detailed roadmap for managing security risks, architecture, and testing, spanning from the design phase to post-market monitoring. Similarly, ANSI/AAMI SW96:2023 outlines how to address security-related risks across the Total Product Life Cycle (TPLC) using the ISO 14971 framework [12][13].
When conducting cybersecurity risk assessments, manufacturers should prioritize exploitability over traditional probability-based calculations. Frameworks like CVSS are recommended to evaluate factors such as attack complexity and the level of privileges required. The FDA also advises regularly scanning for vulnerabilities using resources like CISA's Known Exploited Vulnerabilities (KEV) Catalog and proactively eliminating these from devices, as they are actively targeted by attackers. Importantly, most cybersecurity software patches are classified as design changes that typically don't require prior FDA approval, allowing manufacturers to quickly deploy fixes [12].
Protocols for Secure Data Exchange
Securing data exchange is another critical aspect of balancing security with connectivity. Manufacturers should implement robust technical controls to protect data without compromising functionality. Basic steps include replacing default usernames and passwords with unique credentials and enabling access-control mechanisms. Encrypting data both at rest and in transit is essential to block unauthorized access and prevent network eavesdropping. When using technologies like Bluetooth or standard network protocols, additional security measures may be needed to guard against interception.
With the number of connected medical devices expected to reach 94.9 million globally by the end of 2024 [12], assessing a device's cyber risk within the larger healthcare ecosystem is increasingly important. A compromised device could potentially serve as an entry point to other critical systems, such as Electronic Health Records (EHR) [13]. By addressing risks from both malicious attacks and configuration errors, manufacturers can create devices that support seamless data sharing while meeting the high-security standards required in healthcare environments.
Using Tools for Compliance and Risk Management
Managing compliance and risk in the world of networked medical devices is no small feat. With the FDA emphasizing the need for "continual maintenance" of cybersecurity throughout a product's lifecycle - from design to postmarket distribution - it's clear that good intentions alone won't cut it [4]. The growing ecosystem of connected devices demands tools that can keep up, particularly when it comes to tracking software vulnerabilities and ensuring interoperability.

Conclusion
Balancing interoperability with security has become a key focus under the FDA's evolving regulations. Phil Englert, Director of Medical Device Security at Health-ISAC, emphasizes that cybersecurity engineering plays a critical role in preventing devices from performing unintended actions - a software quality issue the FDA links directly to patient safety concerns [14]. This viewpoint highlights the necessity of integrating security and interoperability to safeguard the expanding network of connected medical devices [12].
The FDA's transition to the Quality System Management Regulation (QMSR) weaves cybersecurity requirements into the Quality Management System across the entire product lifecycle. From the early stages of design validation to post-market surveillance, manufacturers must ensure devices can securely and effectively communicate within hospital networks [2][14]. This regulatory update calls for practical, scalable solutions to maintain rigorous oversight.
To meet these demands, manufacturers need structured frameworks and automated tools for continuous monitoring and documentation. The FDA's Compliance Program Manual (#7382.850), effective February 2, 2026, provides clear guidelines for cybersecurity enforcement during inspections. This makes having audit-ready data not just beneficial but essential [1].
Solutions like Censinet RiskOps™ simplify this process by centralizing risk management for medical devices, clinical applications, and supply chains. By adopting such platforms, manufacturers can align with the robust security measures required by the FDA. AI-driven workflows, which streamline security questionnaires and manage vulnerabilities, further enable organizations to scale compliance efforts efficiently. These approaches reflect the FDA's stance that cybersecurity must be a shared organizational responsibility, extending beyond the IT department [2].
