Frequently asked questions

What are the cybersecurity requirements for an FDA De Novo submission?

Short answer: De Novo cybersecurity submission is a discrete deliverable inside the Secure Product Development Framework (SPDF). FDA expects it documented, traceable, and version-controlled inside your QMS. For the full context, work through the relevant section above and the linked services below - every answer here is grounded in current FDA guidance and the standards your reviewer is using.

How does Section 524B affect De Novo classification requests?

Short answer: Treat it as a process, not a one-off document: own the requirement in design controls, map it to a current standard, generate evidence during V&V, and surface the residual risk in your postmarket plan. For the full context, work through the relevant section above and the linked services below - every answer here is grounded in current FDA guidance and the standards your reviewer is using.

Do I need a full SBOM for a De Novo medical device?

Short answer: Yes - under Section 524B and the February 2026 final guidance, every cyber device requires the artifact in question. Skipping it is the fastest way to an RTA hold. For the full context, work through the relevant section above and the linked services below - every answer here is grounded in current FDA guidance and the standards your reviewer is using.

How is threat modeling different for a De Novo device vs a 510(k)?

Short answer: The two are complementary, not interchangeable. Use this guide's comparison table to decide which one your submission needs and where the overlap saves you re-work. For the full context, work through the relevant section above and the linked services below - every answer here is grounded in current FDA guidance and the standards your reviewer is using.

What happens if the FDA issues a cybersecurity deficiency for my De Novo?

Short answer: It depends on the device classification, intended use, and connectivity profile - but the controlling references are FDA's February 2026 premarket guidance, AAMI SW96, and IEC 81001-5-1. The sections above walk through how each applies. For the full context, work through the relevant section above and the linked services below - every answer here is grounded in current FDA guidance and the standards your reviewer is using.

Does a De Novo submission require independent penetration testing?

Short answer: Yes - under Section 524B and the February 2026 final guidance, every cyber device requires the artifact in question. Skipping it is the fastest way to an RTA hold. For the full context, work through the relevant section above and the linked services below - every answer here is grounded in current FDA guidance and the standards your reviewer is using.
