How Blue Goat Cyber Approaches SaMD cybersecurity FDA requirements

We treat SaMD cybersecurity FDA requirements as a regulated engineering workstream, not a one-time document drop. Every engagement is led by senior medical-device security engineers who have shipped 250+ FDA cybersecurity submissions across 510(k), De Novo, PMA, and EU MDR pathways. Here is how we run it end to end:

• Scoping against your device profile. We baseline connectivity, interfaces, data flows, and intended use before we touch a template - because reviewer expectations for a Class II wearable are not the same as a networked hospital platform.
• Standards mapping in writing. Every deliverable is traced to the February 2026 FDA premarket cybersecurity guidance, AAMI SW96, AAMI TIR57 / TIR97, IEC 81001-5-1, and ISO 14971 - with the citation in the artifact itself so reviewers do not have to guess.
• Evidence generated inside your QMS. Threat models, SBOMs, security risk assessments, and test reports are versioned under design controls so the traceability from requirement → test → residual risk holds up under audit.
• Independent testing where it counts. Penetration testing and vulnerability analysis are executed by a testing team that does not also write the design - the separation FDA reviewers increasingly expect on cyber devices.
• Deficiency-ready posture. We anticipate the RTA, AI-letter, and Major deficiency patterns FDA has issued over the past 24 months and pre-empt them in the initial submission, cutting the odds of a second review cycle.
• Postmarket handoff, not abandonment. Every premarket package leaves you with a working postmarket monitoring plan, CVD process, and update cadence so the evidence you shipped stays defensible after clearance.

If you want that treatment applied to your SaMD cybersecurity FDA requirements package, our FDA Premarket Cybersecurity Services and FDA Cybersecurity Deficiency Response engagements are the two most common entry points.

Frequently asked questions

What are the FDA cybersecurity requirements for SaMD?

Short answer: SaMD cybersecurity FDA requirements 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.

Does SaMD require a Softare Bill of Materials (SBOM)?

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 does FDA Section 524B affect software-only medical devices?

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 penetration testing required for SaMD FDA clearance?

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.

How do I document threat modeling for a software medical device?

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.

What is the difference between premarket and postmarket SaMD cyber requirements?

Short answer: SaMD cybersecurity FDA requirements 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.
