Penetration testing is crucial for medical devices to identify vulnerabilities and ensure regulatory compliance. Unlike generic IT penetration testing, medical device penetration testing requires specialized expertise due to unique device architectures, patient risks, and stringent regulatory demands.
Black-box alone is not enough. FDA expects credentialed testing across every ring.
Recognize that standard IT penetration testing often fails to identify critical vulnerabilities in medical devices due to a lack of understanding of specialized device architecture, patient risks, and regulatory requirements.
Ensure your penetration testing includes specialized protocols like DICOM, HL7/FHIR, MedRadio, and BLE Medical, as these have unique attack surfaces often overlooked by generalist testers.
Go beyond typical IT pentesting by incorporating hardware and firmware analysis techniques such as bus sniffing, JTAG/UART access, firmware extraction, and protocol fuzzing to uncover deeper vulnerabilities.
Do not limit testing to the device itself. Include cloud backends (AWS, Azure, GCP) and mobile companion applications (iOS, Android) to ensure comprehensive security across the whole ecosystem.
Utilize experienced offensive security experts for manual testing to discover logic flaws, business workflow vulnerabilities, and chained exploits that automated scanning tools frequently miss.
Insist on detailed, submission-ready documentation that is specifically tailored to the latest FDA cybersecurity guidance, such as FDA 2026 Premarket Cybersecurity Guidance, to avoid delays and rejections.
Initiate the penetration testing process with a detailed discovery and scoping phase to clearly define the device, its intended use, connectivity, and data flows, leading to a tailored testing plan.

Quick answers to the questions teams most often ask about this topic.
Yes, for cyber devices the FDA expects security testing evidence including penetration testing in the premarket submission. The testing scope must cover the device, its interfaces, and supporting systems, and the report must document methodology, findings, and remediation.
At minimum before submission and after any significant change. Most mature programs also schedule annual postmarket pentests and re-test after major firmware releases or newly disclosed component vulnerabilities.
Hardware interfaces (USB, JTAG, debug ports), firmware, wireless protocols (Bluetooth, Wi-Fi, cellular), cloud and mobile app components, update mechanisms, and authentication. Both black-box and credentialed testing are typically used.
