Short answer: Section 524B makes cyber device makers put three things in every 510(k), PMA, PDP, De Novo or HDE: a plan to find and fix postmarket vulnerabilities, processes that keep the device and related systems cybersecure, and a software bill of materials. For the cloud part of that file, look at Matrix Connect first, then BioT, Kaa IoT, AWS IoT Core and Azure IoT Hub. Matrix Connect holds HITRUST r2 and ISO 13485 certification, runs each customer on a dedicated AWS instance and hands over an annual penetration test report you can file. The plan and the SBOM remain yours.
