Start a Medical Device Cybersecurity Firm

1. 1

   Learn the two customers and their two different problems

   Medical device cybersecurity serves two distinct buyers. Device MAKERS need to build security into their products and document it: the FDA now requires premarket cybersecurity information in device submissions (threat modeling, a software bill of materials, vulnerability management plans, and a plan for postmarket security), so a maker cannot clear a connected device without it. HOSPITALS need to secure the thousands of devices already on their networks: inventory, risk assessment, network segmentation, and monitoring, because each connected device is a potential attack path into patient care. Decide which buyer you serve first, or serve both with the same underlying expertise, but understand their problems are not the same.

2. 2

   Build the specialized expertise that separates you from generalists

   General IT security is not enough here, which is exactly why the niche is open. Medical devices have constraints ordinary IT does not: they cannot always be patched on a normal schedule, they run for many years, they are safety-critical (a security control that disrupts device function can harm a patient), and they carry regulated software. You need to combine security fundamentals with device and clinical-engineering realities and with the FDA framework. That specific combination is scarce, and it is your moat; a founder who has both a security background and biomedical or healthcare-IT experience is unusually well positioned.

3. 3

   Package premarket-documentation services for device makers

   For manufacturers, the concrete, sellable deliverables map to FDA expectations: threat modeling and security risk assessment, generating and managing a software bill of materials (SBOM), vulnerability assessment and penetration testing of the device, and preparing the cybersecurity documentation the submission requires. These are defined, urgent, and tied to a clearance the maker cannot get without them, which makes them easy to scope and price. Pair naturally with the FDA regulatory consultants (their own card) who handle the rest of the submission.

4. 4

   Package assessment and monitoring for hospitals

   For facilities, the offer is a lifecycle: a connected-device inventory and risk assessment, network segmentation recommendations that isolate vulnerable devices without disrupting care, vulnerability monitoring, and incident-response planning specific to medical devices. Because devices live on the network for years and new vulnerabilities appear constantly, the initial assessment naturally converts into ongoing monitoring and advisory retainers, which is where the durable revenue sits.

5. 5

   Set up as a credible, insured firm

   LLC, professional liability insurance sized for security work, engagement letters, and, for any hands-on testing, careful rules of engagement so you never disrupt a live clinical device or patient care during an assessment. Relevant security credentials plus demonstrable medical-device knowledge are your credibility. Handle any protected health information you encounter under HIPAA with a business associate agreement. In a safety-critical setting, the discipline of your testing methodology is itself part of what you sell.

6. 6

   Grow with the regulatory and threat weather

   The demand grows as regulations tighten and attacks increase, so being the specialist who explains each new FDA guidance or threat clearly is a business development engine. Convert one-off assessments and submissions into ongoing security-partner retainers, build repeatable methodologies so you can add specialists, and deepen into device categories or hospital-system relationships as your reputation compounds. This is a rising niche; the operator who establishes expertise early owns a durable position.

Best for: Cybersecurity professionals, biomedical or clinical engineers, and healthcare IT specialists

Not for: Not for a generic IT security consultant unwilling to learn the safety-critical, regulated realities of medical devices, because that gap is the whole point. Not for anyone careless about testing a live clinical environment, since disrupting a device can harm a patient. And not for those who want one-off projects only, because the durable business is the ongoing monitoring retainer.
