    FDA postmarket cybersecurity 'update letter' cadence increases

    Blue Goat Cyber tracking shows a year-over-year jump in postmarket cybersecurity update letters citing missing CVD URLs, stale SBOMs, and lack of triage SLAs.

    What changed

    • More letters are referencing the 2026 premarket guidance for postmarket expectations.
    • Top deficiency themes: missing/stale CVD URL, SBOM not refreshed in 12+ months, no documented triage SLA.

    Action for manufacturers

    Run a one-day postmarket hygiene sprint: publish or update CVD URL on the device label and security.txt, regenerate SBOM+VEX, and put a numeric triage SLA in your SOP.
