Software as a Medical Device (SaMD) Cybersecurity
SaMD - software that meets the medical-device definition without being embedded in hardware - is one of the fastest-growing FDA submission categories and one of the most cybersecurity-sensitive. Cloud backends, mobile apps, and standalone clinical software inherit all the FDA premarket requirements plus a much broader attack surface than embedded devices. This hub pulls together the services, guides, blog posts, and standards that explain what SaMD-grade cybersecurity looks like under the Feb 2026 guidance, IEC 62304, IEC 81001-5-1, and Section 524B.
The short answer
Software as a Medical Device is a cyber device whenever it has software and the ability to connect to the internet, which is nearly always. The cybersecurity package is the same as for hardware, with the emphasis shifted to the hosting environment: cloud architecture and tenancy, authentication and session management, API security, third-party and open-source dependency management, and update delivery. Reviewers expect the security architecture views to show the cloud and mobile components, not stop at the app boundary.

Standards & guidance
Defined entries from our MedTech Cybersecurity Standards Glossary.
- FDA 2026 GuidanceFDA Premarket Cybersecurity Guidance (Feb 3, 2026)The FDA's final premarket cybersecurity guidance, issued February 3, 2026. Provides nonbinding recommendations for cybersecurity documentation and explains Section 524B obligations. It directly supersedes the June 27, 2025 guidance; September 2023 was a final guidance, not a draft.
- Section 524BFD&C Act Cyber Device RequirementsSection 524B of the FD&C Act (the statutory partner to 21 CFR 807.81) was added by the Consolidated Appropriations Act, 2023. It gives the FDA explicit authority to require a complete cybersecurity package in every premarket submission for a cyber device, and to refuse submissions that lack one. It works alongside 21 CFR 807.81, which sets the 90-day 510(k) filing floor.
- SPDFSecure Product Development FrameworkA documented framework that shows security activities are integrated across the device lifecycle - not bolted on at the end. Includes secure requirements, threat modeling, secure coding, V&V, vulnerability management, and post-market response.
- IEC 81001-5-1Health Software Security ActivitiesThe international standard the FDA points to for the Secure Product Development Framework (SPDF). Defines security activities at each lifecycle stage - planning, requirements, design, implementation, V&V, release, and post-market.
- ISO 14971Medical Device Risk ManagementThe umbrella risk-management standard for medical devices. Defines hazard identification, risk estimation, risk evaluation, risk control, and residual risk evaluation. Cybersecurity risks must be reconciled here so a security control never silently introduces a safety hazard.
- ISO 13485Medical Device Quality Management SystemThe international QMS standard for MedTech. Covers design controls, document control, CAPA, supplier management, and post-market surveillance. The QMSR final rule (effective Feb 2, 2026) harmonizes 21 CFR Part 820 with ISO 13485.

Related FDA deficiencies
The deficiency letters reviewers most often write on submissions in this topic area. Each links to the full response playbook.
- Inadequate Vulnerability Management Plan
Your VM plan lacks defined triage timelines, a coordinated vulnerability disclosure path, or a documented patch-deploy mechanism.
