What the 2026 FDA Cybersecurity Guidance Requires
The February 2026 guidance reshapes how the FDA oversees medical device cybersecurity. Instead of treating it as a separate technical concern, cybersecurity is now fully integrated into Quality Management System (QMS) processes. This shift aligns with the updated Quality Management System Regulation (QMSR), which references ISO 13485:2016. Maven Regulatory Solutions explains:
Cybersecurity is no longer a standalone technical consideration - it is embedded into: Risk Management, Design Controls, Validation Activities, [and] Postmarket Surveillance. [3]
This integration establishes the foundation for several key changes.
Major Changes in the 2026 Guidance
The updated guidance introduces several adjustments that impact how manufacturers and healthcare delivery organizations approach device security. One major change is the requirement for manufacturers to adopt a Secure Product Development Framework (SPDF). This framework covers the entire Total Product Lifecycle (TPLC), including threat modeling, secure architecture design, and penetration testing during both development and deployment.
The FDA now supports a risk-based assurance model, which allows manufacturers to provide digital evidence - such as system logs and automated test results - during audits. This approach simplifies compliance while maintaining safety standards.
Another critical change is the FDA’s authority, effective October 1, 2023, to "Refuse to Accept" (RTA) premarket submissions that fail to meet Section 524B requirements. Additionally, noncompliance with Section 524B(b), which focuses on ensuring device cybersecurity, is classified as a prohibited act under section 301(q) of the FD&C Act. [4]
Requirements for Cyber Devices Under Section 524B
Section 524B applies to any device equipped with software, including firmware or programmable logic, that connects to the internet. The definition of connectivity is broad, covering Wi‑Fi, cellular, Bluetooth, RF, and even hardware connectors like USB or serial ports.
For healthcare delivery organizations, understanding these requirements is essential. They help determine which devices within a facility are subject to stricter oversight. Manufacturers must now include three key elements in their premarket submissions:
- A postmarket monitoring plan to identify and address vulnerabilities within an acceptable timeframe.
- Evidence of cybersecure design and maintenance processes that ensure the device and its related systems remain secure.
- A complete Software Bill of Materials (SBOM) that lists all proprietary, commercial, open-source, and off-the-shelf components. [4]
The term "related systems" broadens the scope to include manufacturer-controlled elements, such as update servers and connections to healthcare facility networks. [1]
Required Documentation and Reporting
Manufacturers are required to provide documentation that demonstrates ongoing security management. SBOMs must be machine-readable and include details on all component types - proprietary, commercial, open-source, and off-the-shelf - so organizations can assess supply chain risks and quickly address vulnerabilities.
Premarket submissions should also include threat models, security architecture views (such as analyses of multi-patient harm scenarios), and patch management plans. Additionally, manufacturers must establish Coordinated Vulnerability Disclosure (CVD) procedures to address vulnerabilities identified by both internal teams and external researchers. Device labeling must supply enough information for healthcare facilities to securely configure, update, and manage devices within their networks.
The level of documentation required depends on the device’s cybersecurity risk. Even simpler devices may need robust controls if they connect to a network or operate within safety-critical environments. For modified devices, full 524B documentation is required if cybersecurity is impacted; otherwise, a summary assessment will suffice. [4]
Compliance Challenges for HDOs
While manufacturers are required to adhere to FDA mandates, Healthcare Delivery Organizations (HDOs) encounter practical difficulties when incorporating cybersecurity into their existing systems. Shifting cybersecurity from being treated as a separate technical issue to embedding it within Quality Management Systems (QMS) introduces complexities across multiple departments. One of the primary hurdles lies in adapting legacy quality systems to accommodate cybersecurity needs.
Adding Cybersecurity to Existing QMS
HDOs have traditionally designed their Quality Management Systems with a focus on clinical risk management, often sidelining cybersecurity considerations. However, the 2026 guidance mandates that security events be integrated into existing Corrective and Preventive Action (CAPA) processes. This means that vulnerabilities must now trigger formal quality actions, requiring collaboration between IT security teams, clinical engineering, and quality assurance. Regulatory guidance emphasizes that cybersecurity is no longer an isolated concern but a core element of risk management, design controls, validation processes, and postmarket surveillance.
Assessing Vendor and Device Inventory
Updating internal systems is only part of the challenge. HDOs must also map out their device ecosystems to determine which devices meet the "cyber device" criteria. This involves identifying devices equipped with technologies like Wi-Fi, cellular, Bluetooth, RF communications, or hardware connectors such as USB, Ethernet, or serial ports. Even older devices not originally designed for internet connectivity but featuring interfaces like USB ports fall under this definition. Additionally, HDOs must evaluate connected systems, including manufacturer-controlled update servers and facility networks, broadening the scope of the inventory process.
Maintaining SBOMs and Patch Updates
Managing Software Bills of Materials (SBOMs) is another ongoing challenge. HDOs are required to secure machine-readable SBOMs that comply with the NTIA's seven mandatory fields. Matthew Hazelett, Cybersecurity Policy Analyst at the FDA, underscores this requirement:
Manufacturers should provide machine-readable SBOMs, and that they should be consistent with the minimum elements... identified in the October 2021 National Telecommunications and Information Administration, or NTIA, Multistakeholder Process. [5]
Once collected, this data must be cross-referenced against vulnerability resources such as the NIST National Vulnerability Database and CISA's Known Exploited Vulnerability Catalog. HDOs must also monitor the support status and end-of-life timelines for every software component, adding another layer of complexity to the process.
Monitoring Vulnerabilities After Market Release
The challenges don’t end with premarket preparations. Postmarket surveillance requires HDOs to maintain continuous oversight of vulnerabilities. They must differentiate between routine updates and patches addressing critical risks. Manufacturers are expected to provide patches on "reasonably justified regular cycles" for known vulnerabilities and deliver "out-of-cycle" updates for critical issues "as soon as possible." [5] If a vulnerability cannot be patched, manufacturers must share all relevant details to enable "responsible risk transfer", leaving HDOs to implement compensating controls.
This level of vigilance demands dedicated teams to monitor vulnerabilities, engage with organizations like Health-ISAC, manage Coordinated Vulnerability Disclosure procedures, and coordinate responses across clinical and IT teams. Many HDOs are still in the process of developing these capabilities, making this an area of significant operational growth.
How HDOs Can Achieve Compliance
To meet FDA cybersecurity requirements, healthcare delivery organizations (HDOs) must weave cybersecurity into their quality systems, operational workflows, and vendor relationships. The FDA emphasizes that medical device cybersecurity is a shared responsibility among key players, including healthcare facilities, patients, providers, and device manufacturers. This means HDOs can’t just rely on manufacturers - they need to actively manage risks within their own frameworks, such as the NIST Cybersecurity Framework. A strong starting point for this is establishing comprehensive development protocols.
The FDA's Quality Management System Regulation (QMSR) under 21 CFR Part 820 aligns with ISO 13485:2016, requiring risk management throughout a product’s entire lifecycle. This approach ensures cybersecurity isn’t treated as a separate issue but is integrated into existing quality processes. Additionally, Section 524B of the FD&C Act, effective March 29, 2023, enforces specific mandates for cyber devices, reinforcing the need for a proactive approach.
Building a Secure Product Development Framework
HDOs should work with vendors that adopt a Secure Product Development Framework (SPDF). This framework helps minimize vulnerabilities across the device lifecycle - from design to decommissioning. SPDF is not just a technical add-on; it’s a critical part of product development, risk management, and quality systems.
When assessing vendors, HDOs should examine security architecture documentation to confirm that devices meet five key security objectives:
- Authenticity: Verifying the source of software updates.
- Authorization: Managing user access controls effectively.
- Availability: Ensuring devices remain functional during cyber incidents.
- Confidentiality: Protecting patient health information (PHI) during data exchanges.
- Updatability: Establishing workflows for timely software patches.
Device labeling also plays a crucial role. It should outline secure configuration and update procedures. Pay special attention to devices with hardware connectors like USB or Ethernet ports, as the FDA considers these features capable of internet connectivity, even if HDOs don’t plan to use them that way.
Managing Post-Market Cybersecurity Activities
Post-market cybersecurity management involves integrating internal assessments and external feedback into Corrective and Preventive Action (CAPA) systems to address vulnerabilities quickly.
HDOs should actively implement FDA safety communications and alerts to mitigate risks from unpatched devices. Incident playbooks, such as the "Medical Device Cybersecurity Regional Incident Preparedness and Response Playbook", can prepare organizations for large-scale impacts. Additionally, reporting cybersecurity issues through the MedWatch voluntary report form (Form 3500) helps the FDA and manufacturers identify emerging threats.
For devices still in use but no longer marketed, HDOs must manage the Total Product Life Cycle (TPLC). This includes ensuring risk management documentation accounts for differences between devices in the field and those currently marketed. Organizations without sufficient internal resources can turn to regional mutual aid partnerships to address legacy and third-party risks.
Securing vendor relationships is another critical piece of the puzzle.
Managing Third-Party Risk
Vendor risk management begins during procurement. HDOs should require vendors to provide a Software Bill of Materials (SBOM) and a vulnerability management plan during premarket submissions. The SBOM should detail all software components - commercial, open-source, and off-the-shelf - to identify potential supply chain vulnerabilities.
Accountability frameworks are essential. These frameworks should assign manufacturers the responsibility for identifying and addressing cybersecurity risks throughout the product lifecycle. Vendors must also have procedures for coordinated vulnerability disclosures, including those identified by third-party software suppliers and researchers.
Senior management needs to oversee risk management processes and track key metrics, such as the time from vulnerability detection to patch release and full implementation in deployed devices. Participation in Information Sharing and Analysis Organizations (ISAOs), like the Health Information Sharing & Analysis Center (H-ISAC), can provide access to valuable threat intelligence and keep HDOs informed about emerging risks.

Conclusion
The FDA's 2026 cybersecurity guidance is changing how healthcare delivery organizations (HDOs) handle medical device security. By stating that "reasonable assurance of cybersecurity" is now a legal component of a device's safety and effectiveness, the FDA underscores the direct link between cybersecurity and patient outcomes [1]. This goes beyond just meeting regulations - it's about protecting the devices that healthcare facilities rely on every day.
"These recommendations are intended to promote consistency, facilitate efficient premarket review, and help ensure that marketed medical devices are sufficiently resilient to cybersecurity threats." - FDA [2]
One key benefit for HDOs is the visibility provided by Software Bills of Materials (SBOMs). These detailed inventories of software components make it easier to identify vulnerabilities and respond quickly. They also strengthen long-term resilience by ensuring that every part of a device's software ecosystem is accounted for. Along with standardized coordinated vulnerability disclosure (CVD) processes and clear patch management timelines, HDOs can reduce medical device security risks and maintain secure, interoperable networks [1].
The guidance takes a broad view of cybersecurity, addressing everything from the devices themselves to update servers and network connections within healthcare facilities. For organizations managing large inventories of connected devices, this comprehensive strategy helps prevent disruptions that could impact patient care.
