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 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.
• 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.

  Response playbook
• Missing Cybersecurity Risk Assessment

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

  How is PMA cybersecurity different from a 510(k)?

  PMA cybersecurity packages go deeper on every section. Threat models cover safety-critical clinical scenarios end-to-end, not just connected interfaces; pen testing typically includes white-box review of safety-critical firmware paths; the postmarket plan must defend the device through its full intended lifetime, not just the next clearance cycle. Reviewers also issue more cybersecurity deficiencies on PMAs than on any other pathway, so the bar for evidence quality is higher.

  Does Section 524B apply to IDE submissions?

  No. Section 524B(a) enumerates 510(k), De Novo, PMA, PDP, and HDE; an IDE is submitted under a different section of the FD&C Act. Cybersecurity still applies through binding regulation: 21 CFR 812.25 requires the investigational plan to describe the device, the methodology, and the risks to subjects, and the February 3, 2026 guidance describes the cybersecurity content FDA expects there. The distinction matters because the content lands in the investigational plan rather than in an eSTAR cybersecurity section.
