Evolving global cybersecurity regulations: Challenges and opportunities for medtech teams

The landscape of medical device regulations continues to undergo significant changes globally. Most recently, there have been some noticeable shifts in how regulators are approaching the cybersecurity of medical devices. Recent updates from leading regulatory bodies, including the U.S. Food and Drug Administration (FDA), the European Union (EU), and the International Medical Device Regulators Forum (IMDRF), signal a united front in the drive to enhance the cybersecurity measures of medical devices.  

The essence of these updates is clear: Cybersecurity is considered a fundamental aspect of medical device safety and efficacy. The FDA's proposed guidance adjustments, the EU's stringent requirements under the MDR and IVDR, and IMDRF's global harmonization efforts are reshaping the regulatory requirements for a broad range of device types. These changes underscore the importance of integrating robust cybersecurity protections from the earliest stages of device design to their operational lifespan.

With the ever-increasing incidents of security perimeter and data breaches, this transition while warranted, presents challenges for manufacturers to elevate their cybersecurity practices, to innovate with security in mind, and to navigate a complex global regulatory landscape. Yet, it also opens up opportunities to lead in the development of safer, more secure medical technologies that earn the trust of patients and healthcare providers alike.

FDA Cybersecurity Guidances

In the evolving landscape of medical device regulation, the FDA has proposed pivotal updates to its cybersecurity guidance, aiming to fortify the resilience of medical devices against cyber threats. This move reflects the growing interconnectedness of medical devices and the escalating sophistication of cyber threats targeting the healthcare sector. The FDA's draft guidance, "Select Updates for the Premarket Cybersecurity Guidance: Section 524B of the FD&C Act," introduces an entirely new section dedicated to enhancing device cybersecurity throughout its lifecycle. This update emphasizes the criticality of integrating cybersecurity measures from the design phase through the entire lifespan of the device, encompassing premarket authorization, 510(k) clearances, De Novo requests, and more.  

One of the significant highlights from the FDA's proposal is the emphasis on ensuring that devices capable of internet connectivity, whether intentionally or unintentionally, maintain stringent cybersecurity safeguards. This perspective stems from an understanding that the ability to connect to the internet inherently poses potential cybersecurity risks. It also expands best practices for cybersecurity within the medical device sector, building on the earlier adoption of a Secure Product Development Framework (SPDF). This framework aims to minimize vulnerabilities in medical devices by incorporating robust processes throughout the product development lifecycle. The guidance also stresses the importance of transparency, urging manufacturers to provide users with comprehensive cybersecurity controls, potential risks, and technical details through labeling. This approach is intended to empower users to manage cybersecurity risks effectively and respond promptly to any identified issues.

In addition to the FDA updates to cybersecurity guidance within medical device regulations, similar positions have been taken by other global regulatory bodies, recognizing the critical importance of cybersecurity in medical devices. As these frameworks get enacted and updated, the industry is seeing a unified drive toward enhancing the cybersecurity of medical devices, reflecting the global nature of both healthcare and cyber threats.

European Union (EU) Cybersecurity Guidelines

The European Union has continued to be proactive in addressing cybersecurity concerns through the Medical Device Regulation (MDR) and the In Vitro Diagnostic Regulation (IVDR). The MDR, which came into full application in May 2021, and the IVDR, fully applicable from May 2022,  incorporate specific requirements for ensuring the cybersecurity of medical devices. These regulations require manufacturers to consider cybersecurity at all stages of a device's lifecycle, from initial conception to decommissioning.  

More recently, the EU has introduced updates to the Cyber Resilience Act  and drafted a new EU cybersecurity rule to establish a European cybersecurity certification scheme (“ECCS”). The ECCS  would introduce a detailed certification process, prohibiting self-assessment even for low-risk products. It mandates vulnerability disclosure for certified products, sets rigorous expectations for regulators and certification bodies, including regular product sampling and peer assessments, and requires a proactive approach to vulnerability management. The ECCS also would allow for the mutual recognition of standards internationally and mandate the consolidation of existing national certification schemes. This comprehensive approach highlights the EU's commitment to enhancing cybersecurity across the board.  

IMDRF Cybersecurity Guidelines

The International Medical Device Regulators Forum (IMDRF) has also published guidance aimed at harmonizing cybersecurity practices. The IMDRF's guidelines focus on principles for medical device cybersecurity, which include risk management, post-market surveillance, and information sharing amongst stakeholders. These guidelines serve as a reference point for both regulators and manufacturers, aiming to foster a unified approach to addressing cybersecurity risks.

Impact on Device Manufacturers

Manufacturers must navigate these evolving regulatory landscapes, ensuring their devices comply with each jurisdiction's specific requirements. This means incorporating robust cybersecurity measures from the design phase through the entire product lifecycle. Expectations include the ability to update and patch devices in the field, conduct thorough risk assessments, and maintain transparency about a device's cybersecurity measures.  The impact of these changes means that medtech design and commercialization pipelines will need to incorporate cybersecurity as a core component, rather than an afterthought. Manufacturers should anticipate:

  1. Increased Scrutiny: Regulatory submissions will likely require more detailed cybersecurity information, including evidence of risk assessments and mitigation strategies.
  1. Lifecycle Management: There will be a need for plans to address cybersecurity throughout a device’s lifecycle, including mechanisms for providing updates and patches.
  1. Global Harmonization: While regulations may vary in specifics from one region to another, the overarching principles of ensuring device safety and effectiveness through cybersecurity measures are consistent. Manufacturers looking to enter multiple markets will benefit from developing products that meet high cybersecurity standards capable of satisfying various regulatory requirements.

The Path Forward for Medtech Cybersecurity

As medical devices become increasingly interconnected and reliant on digital technologies, the importance of cybersecurity cannot be overstated. The FDA’s, European Union’s, and IMDRF’s updates are part of a broader global movement towards securing medical devices against cyber threats. Manufacturers must stay informed about these regulatory changes, integrating cybersecurity into every stage of their device’s development and lifecycle in order to properly comply with regulatory requirements.  

Manufacturers and stakeholders should also closely monitor developments in cybersecurity regulations across all jurisdictions where they operate or plan to market their devices. Engaging with regulatory bodies, participating in industry forums, and adopting best practices in cybersecurity will be key strategies for navigating these evolving landscapes successfully and ensuring the trustworthiness and resilience of medical devices in the digital age.
