Why FDA reviewers look at your threat model before they look at your findings, and how we build one for connected devices, companion apps, and backend APIs.

Scope the device, cloud, and mobile companion, AI agents map the attack surface, a senior tester confirms exploitability, and you receive an FDA premarket-ready package.
From kickoff to auditor-ready report, delivered in 48 hours.
The FDA's 2023 premarket guidance now requires cybersecurity testing evidence. Submissions without penetration test results face Refuse to Accept (RTA) decisions.
Vulnerabilities in medical devices can directly impact patient health. Proactive testing prevents potentially life-threatening security incidents.
Medical device security firms charge $30K to $80K for comprehensive testing. StealthNet delivers a submission-ready hybrid engagement for a fixed $5,000 to $10,000.
$5,000 to $10,000
Fixed fee, quoted before any work begins
Best for: Premarket 510(k) and PMA submissions, MDR technical documentation, device and companion app testing
$1,500
Not submission evidence. See the note below.
Best for: Post-market monitoring, interim testing between submissions, internal baseline
Single application
One API or one companion app, one role. Lands near the bottom of the range.
Multi-component submission
Inference or device API, plus the model or firmware layer, plus a containerized or on-premise deployment package. This is the most common 510(k) scope and lands near $7,500.
Multi-device program
Several devices or a full product family. Quoted above the range.
Most 510(k) submissions we test are multi-component. You get a fixed fee before any work starts, so the number on your SOW is the number you pay.
Which one does the FDA actually expect?
A 510(k) or PMA cybersecurity submission needs testing performed and documented by a qualified third party, with named human testers accountable for the findings. StealthStrike is AI-only, so we do not put it forward as submission evidence and we will tell you so on the call. Use it for post-market monitoring or a baseline read between formal engagements. For anything going in front of a reviewer, start with Hybrid.
