The Shift from Safety Risk to Security Risk

The Shift from Safety Risk to Security Risk — make sure your design history file documents the rationale, the standard you mapped to, and the objective evidence that closes the loop. Reviewers expect to trace the requirement, the test, and the residual risk in a single thread.

Vulnerability Identification and Analysis — make sure your design history file documents the rationale, the standard you mapped to, and the objective evidence that closes the loop. Reviewers expect to trace the requirement, the test, and the residual risk in a single thread.

Risk Evaluation: Impact vs. Likelihood

Risk Evaluation: Impact vs. Likelihood — make sure your design history file documents the rationale, the standard you mapped to, and the objective evidence that closes the loop. Reviewers expect to trace the requirement, the test, and the residual risk in a single thread.

Control Implementation and Verification

Control Implementation and Verification — make sure your design history file documents the rationale, the standard you mapped to, and the objective evidence that closes the loop. Reviewers expect to trace the requirement, the test, and the residual risk in a single thread.

IEC 81001-5-1 vs. FDA Premarket Guidance

IEC 81001-5-1 vs. FDA Premarket Guidance is one of the areas FDA reviewers probe hardest in modern submissions. The points below summarize what we ship in client packages and what we have seen FDA accept and reject across 250+ device submissions.

Mapping Standards to FDA Documentation Requirements

Mapping Standards to FDA Documentation Requirements — make sure your design history file documents the rationale, the standard you mapped to, and the objective evidence that closes the loop. Reviewers expect to trace the requirement, the test, and the residual risk in a single thread.

Addressing Security Risk in Section 524B Submissions

Addressing Security Risk in Section 524B Submissions — make sure your design history file documents the rationale, the standard you mapped to, and the objective evidence that closes the loop. Reviewers expect to trace the requirement, the test, and the residual risk in a single thread.

Common Pitfalls in Security Risk Assessments

Common Pitfalls in Security Risk Assessments is one of the areas FDA reviewers probe hardest in modern submissions. The points below summarize what we ship in client packages and what we have seen FDA accept and reject across 250+ device submissions.

Expert Support for IEC 81001-5-1 Compliance

Expert Support for IEC 81001-5-1 Compliance is one of the areas FDA reviewers probe hardest in modern submissions. The points below summarize what we ship in client packages and what we have seen FDA accept and reject across 250+ device submissions.

Frequently asked questions

How does IEC 81001-5-1 differ from ISO 14971?

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.

Is IEC 81001-5-1 mandatory for FDA medical device submissions?

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.

What are the specific security life cycle activities required by IEC 81001-5-1?

Short answer: IEC 81001-5-1 security risk assessment 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 do you integrate threat modeling into an IEC 81001-5-1 assessment?

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.

Does IEC 81001-5-1 apply to SaMD (Software as a 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.
