510(k) Cybersecurity

510(k) is the most common FDA premarket pathway for cyber-enabled devices, and it's also where most cybersecurity deficiencies surface. The Feb 2026 final guidance and Section 524B raised the bar on what reviewers expect to see in the seven-section eSTAR cybersecurity package. This hub pulls together the services, guides, blog posts, standards, and FAQs that cover what a 510(k)-grade cybersecurity submission looks like - and the deficiency patterns we see most often when one isn't.

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, effective February 3, 2026. Defines the seven-section cybersecurity submission format reviewers now enforce at Technical Screening, replacing the 2023 draft. Operationalizes Section 524B of the FD&C Act.
• Section 524BFD&C Act Cyber Device RequirementsAdded by the Consolidated Appropriations Act, 2023, Section 524B 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.
• eSTARElectronic Submission TemplateFDA's mandatory interactive submission template with structured upload slots for each cybersecurity artifact.
• 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.
• ANSI/AAMI SW96Medical Device Security Risk ManagementThe consensus standard for medical device security risk management - asset, threat, vulnerability, likelihood, severity, and residual risk acceptability.
• 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.

• Incomplete Threat Model

  Reviewers say your STRIDE/attack-tree analysis misses interfaces, trust boundaries, or post-market threat surfaces.

• Missing Security Architecture Views

  Your submission is missing one or more of the architecture views FDA 2026 expects (global system, multi-patient, updateability).

  Response playbook
• Insufficient Penetration Testing Evidence

  Reviewers find your penetration test scope too narrow, methodology unclear, or testers insufficiently independent.

• Missing Cybersecurity Risk Assessment

  Reviewers cannot find a cybersecurity risk assessment distinct from the ISO 14971 safety risk file, or the integration is unclear.
