Tools and Processes for Medical Device Cybersecurity | FDA Premarket Guidance Explained

The FDA’s 2022 update to its Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions guidance signaled a clear shift: cybersecurity is no longer an afterthought, it’s a core quality requirement.This whitepaper explores the tools and processes necessary for medical device manufacturers (MDMs) to meet these expectations. It introduces the FDA’s secure product development framework (SPDF), maps guidance requirements to specific actions, and highlights how MedCrypt’s technology portfolio helps manufacturers address key areas like cryptography, vulnerability management, device monitoring, and postmarket security.

• R&D leaders and engineering managers building connected medical devices
• Quality and regulatory affairs professionals responsible for 510(k), PMA, or De Novo submissions
• CISOs, product security leaders, and risk managers developing SPDF programs
• Executives seeking to balance cost, compliance, and innovation in product design

• R&D leaders and engineering managers building connected medical devices
• Quality and regulatory affairs professionals responsible for 510(k), PMA, or De Novo submissions
• CISOs, product security leaders, and risk managers developing SPDF programs
• Executives seeking to balance cost, compliance, and innovation in product design

• The FDA’s premarket guidance links cybersecurity directly to device safety and effectiveness.
• Manufacturers must document processes and tools that address risk, resilience, and transparency.
• Early investment in security architecture reduces postmarket cost and compliance burden.
• MedCrypt’s solutions directly support SPDF implementation through cryptography, SBOM management, and device monitoring.
• A build–buy–partner strategy accelerates compliance while maintaining design flexibility.
