Threat Modeling for Cardiovascular Devices
Threat models for pacemakers, ICDs, monitors, and remote-follow cloud - STRIDE/TARA traced to ISO 14971 hazards. Programmer, telemetry, and backhaul covered.
Last reviewed March 2026 · Reviewed against the FDA Feb 3, 2026 final premarket cybersecurity guidance.
Cardiac device threat models have to span a multi-decade deployed lifetime and four distinct compute elements: implant, in-clinic programmer, home monitor, and cloud follow-up service. The 2017 St. Jude/Abbott recall is the textbook example of a threat model that didn't include 'home monitor as an attack pivot,' and reviewers in this segment are now explicitly looking for that scenario. We deliver STRIDE-per-element threat models that treat each of those four elements as a separate trust domain, model the data flows between them, and trace every identified threat to an ISO 14971 hazard and a risk control.
We model the programmer↔implant interface for spoofing, tampering, and elevation-of-privilege at the protocol level. We model the home monitor as 'attacker-controlled' explicitly - what can it do beyond passive telemetry relay? - because that's the real-world incident pattern. We model the cellular/Wi-Fi backhaul for MITM and impersonation, and the cloud APIs for tenant isolation and broken authorization. Crucially for this segment, we layer in a postmarket threat model: how does the threat landscape change when a CVE drops on a library that's deployed in a million implants you cannot recall? The output is an AAMI SW96 + AAMI TIR97 aligned threat document that lands in eSTAR cleanly and gives your postmarket team something to operate from.

Medical Device Threat Modeling engagement, end to end
Four phases, fixed fee, scoped to cardiovascular architecture from kickoff onward.
-
01
Architecture intake
Data-flow diagrams, trust boundaries, and asset inventory captured directly from your design team.
-
02
STRIDE workshop
Joint working sessions to enumerate threats per element, mapped to Section 524B(b) and AAMI SW96.
-
03
Risk + mitigation pass
Each threat gets a residual-risk rating, mitigation, and a link to the verification activity that proves it.
-
04
Reviewer-ready package
Threat model document and SPDF section ready to drop straight into eSTAR cybersecurity attachments.
What we see in Cardiovascular medical device threat modeling
The patterns we hit in this segment, this service, again and again.
-
Home monitor not modeled as attacker-controlled
Threat model assumes home monitor is a trusted relay. Reviewer asks the post-2017 question; team has no answer on file.
-
Cloud follow-up tenant isolation not in scope
Cloud architecture diagram treats all clinics as one trust domain. STRIDE-per-element on the cloud APIs not performed.
-
Postmarket scenarios absent
Threat model covers as-shipped device. CVE-on-deployed-fleet, signing-infra compromise, and update-path tampering not analyzed.
-
Programmer-side credential compromise not modeled
Programmer treated as trusted endpoint. Compromised programmer / stolen programmer scenarios absent.
"Blue Goat's knowledge of regulatory requirements versus cybersecurity challenges was highly valuable and readily apparent as we were guided by and worked alongside their team towards the development of a comprehensive and compliant cybersecurity plan for our new medical device. Especially helpful for our company as we are a startup. Their team and competencies nicely filled our resource needs. Thank you Blue Goat!"

Standards that apply
The Cardiovascular baseline, plus the call-outs that matter for medical device threat modeling in this segment.
Segment-specific call-outs
AAMI TIR60601-4-5 + AAMI TIR97
Cardiac reviewers cite these explicitly. Threat model must reference them in the standards-applied section.
FDA postmarket cyber guidance
Postmarket scenarios are required for implant threat models - not optional for this segment.
What's not in scope
We scope tightly on purpose. These items are either out-of-scope by design or belong in a separate engagement - we'll tell you up front, not after kickoff.
- Penetration testing execution (scoped separately)
- Clinical risk analysis under ISO 14971 (we feed it, we do not own it)
- Hospital network architecture review
