Medical device cybersecurity is the practice of protecting connected devices, their software, and patient data from attacks that could cause harm. FDA cybersecurity compliance is now a gating factor for clearance. Since Section 524B took effect, every cyber device submission must include a Secure Product Development Framework, SBOM, threat model, penetration testing, and a postmarket vulnerability program. This pillar is the map to all of it. Need hands-on help? See our medical device cybersecurity services.
Medical device cybersecurity is the discipline of protecting connected, software-driven medical devices from cyber threats across their entire lifecycle - design, premarket submission, manufacturing, clinical deployment, and postmarket. It spans every device that meets the three-part Section 524B definition: it contains software, it has the ability to connect to the internet, and it has technological characteristics that could be vulnerable to cybersecurity threats.
In practice that captures nearly every modern device - BLE-paired wearables, USB-charged hearing aids, cloud-connected infusion pumps, and most SaMD. Risk class is irrelevant. If the device meets the three conditions, the full medical device cybersecurity package is mandatory and the FDA can refuse to accept the submission without it.
Every medical device cybersecurity program maps to the same five-phase SPDF loop. The premarket package the FDA reviews is the evidence trail this loop produces - not a separate deliverable.
Each pillar links to a deep-dive guide or service so you can go as deep as you need.
FDA's statutory cybersecurity requirements for every cyber device submission - what is required, who qualifies as a cyber device, and how reviewers evaluate it.
Explore Section 524B complianceMachine-readable SBOM in CycloneDX or SPDX, with VEX statements that tell reviewers which CVEs are actually exploitable in your device's context.
Explore SBOM & VEXSTRIDE-based threat modeling for medical devices, with trust boundaries, attack surface mapping, and traceability into design controls.
Explore Threat modelingMonthly CVE triage, coordinated vulnerability disclosure, change-controlled patch delivery, and incident response - for the life of the device.
Explore Postmarket monitoringIndependent, exploit-driven testing across hardware, firmware, wireless, BLE, mobile, web, and cloud back end - with a signed Letter of Attestation.
Explore Penetration testingFull medical device cybersecurity package, eSTAR-ready and reviewer-tested across 275+ devices with a no-cost deficiency resolution commitment.

Medical device cybersecurity is not theoretical. Public-record incidents and FDA / CISA advisories span four decades, from the 1985 Therac-25 radiation overdoses through to modern infusion-pump and pacemaker recalls. A full sourced timeline of 86+ events is maintained at Code Blue Chart, our public-record MedTech cyber timeline. A handful that every product team should know:
The pattern is consistent: weak authentication, unsigned firmware, unmaintained third-party components, and missing postmarket monitoring. A modern medical device cybersecurity program is designed to make every one of those failure modes structurally hard.
Reviewer expectations, AAMI SW96, IEC 81001-5-1, and a decade of incident response converge on the same operating model. A defensible medical device cybersecurity program implements all of the following:
US and EU regulators converge on the same goal - safe, resilient devices - but reach it through different instruments. A device shipped in both markets has to satisfy both bars.

Responsibility is shared, but it is not symmetrical. The manufacturer is the accountable party for the security of the device itself; everyone else operates on top of that foundation.
