Premarket to postmarket. One senior team owns every cybersecurity artifact the FDA reviewer will open.
Each FDA finding gets a numbered response with the exact artifact, page reference, and Section 524B citation that closes it.
Same playbook whether the FDA calls it an AINN, additional information request, or deficiency letter - we've responded to all of them.
Refreshed SPDX or CycloneDX SBOM with VEX statements addressing any CVE concerns the FDA raised.
We pen-test only what the FDA asked about - fastest path to closing the file, not padding the invoice.
Structured exactly the way FDA cybersecurity reviewers expect: finding → response → evidence → location in submission.
One quote covers the response and any follow-up exchanges until the cybersecurity file is closed. No retest invoices.
We've responded to hundreds of FDA cybersecurity deficiency letters. The findings cluster into the same handful of categories - these are the ones we close every week.
Reviewer asks for a machine-readable SBOM (SPDX or CycloneDX) with VEX statements addressing every flagged CVE. We rebuild it to FDA expectations.
STRIDE-based threat model missing data-flow diagrams, trust boundaries, or mitigations traced to design controls. We refresh it end-to-end.
Reviewer wants vulnerability testing, fuzz testing, or penetration testing scoped to the device's actual interfaces. We run a targeted retest, not a full re-scope.
Missing traceability between Section 524B(b)(1)-(3) requirements and submission artifacts. We deliver a refreshed matrix the reviewer can check off.
Secure product development framework documentation that doesn't show evidence of execution. We pair the SPDF with artifacts that prove it ran.
Reviewer wants a credible coordinated vulnerability disclosure (CVD) process, SBOM monitoring plan, and patch cadence. We document what you'll actually do.
What you actually get versus a generic regulatory consultant or re-spinning the cybersecurity attachment in-house against the 180-day clock.
