Why this matters

The FDA's Cybersecurity in Medical Devices: Quality Management System Considerations and Content of Premarket Submissions (Feb 3, 2026 final guidance) made cybersecurity documentation a gating criterion for clearance under Section 524B of the FD&C Act. Reviewers now apply this guidance to mdcg 2019-16 & MedTech cybersecurity the same way they apply software lifecycle expectations from IEC 62304 and security risk-management expectations from AAMI TIR57 and ANSI/AAMI SW96:2023.

Gaps in this area are the single most common driver of first-cycle cybersecurity Additional Information (AI) requests. The FDA's FY2024 CDRH performance reports show cybersecurity is among the top deficiency categories cited in 510(k) and PMA AI letters, behind only software documentation and clinical evidence.
