Premarket to postmarket. One senior team owns every cybersecurity artifact the FDA reviewer will open.
Senior reviewer reads your letter, maps every finding to required artifacts, and returns a written closure plan with effort estimate.
Every response is written against the February 2026 final premarket cybersecurity guidance and Section 524B(b)(1)-(3).
Updated cybersecurity content drops directly into eSTAR - no reformatting, no missing attachments, no second hold.
We pen-test, threat-model, and update only what the FDA asked about - fastest path to lifting the hold.
Cover letter and redlines structured the way cybersecurity reviewers want: finding → response → evidence → page reference.
One quote covers the response and any follow-up exchanges with the FDA until the cybersecurity hold is lifted.
Hold letters cluster around a handful of recurring asks. Recognizing the pattern in yours shortens the response cycle.
Single-device STRIDE submissions are getting held for missing fleet-level harm analysis. Most common ask under the February 2026 final guidance.
Component list without affected/not-affected/fixed/under-investigation status for each listed CVE is the second most common hold trigger.
524B(b)(1) requires a written description of how patches reach fielded devices. Verbal process descriptions get held; controlled outputs don't.
Reviewers want to see each pen test finding traced back to a threat-model entry. Standalone pen test reports get held for traceability.
What you actually get versus a generic regulatory consultant or a re-spin in-house while the clock burns.
