Encryption design, key management and provisioning across multiple devices are where surgical robotics submissions get uncertain. Medcrypt pairs former FDA reviewers with security architecture work to clarify what FDA expects before you file.
Where surgical robotics cybersecurity gets hard
Teams can invest heavily in cryptographic design and still lack clear guidance on documentation, key management and acceptable cryptographic implementations.
A surgical tool suite can combine devices built in-house and by third parties, each with its own technology stack and manufacturing environment.
Devices that run in disconnected environments still need secure provisioning, both in the field and during manufacturing, without breaking FDA clearances.
Accessories need authentication to block unauthorized attachments, all within strict performance limits.

Structured workshops evaluate your cryptographic design against FDA guidance and identify what needs strengthening or more documentation.
Threat modelingAssess every key and cipher your device depends on and leave with a mitigation strategy for each gap.
Assess your cryptographyA tailored Root of Trust for each device, secure provisioning and reprovisioning, and accessory authentication under one security architecture.
Data securityTailored security SOPs and a prioritized remediation plan address submission risks and build your team's capability for future submissions.

Section 524B applies to cyber devices: devices that include software validated, installed, or authorized by the manufacturer, have the ability to connect to the internet, and could be vulnerable to cybersecurity threats. The test is whether the device is capable of connecting, not only whether its intended use involves connecting.
In Medcrypt's surgical robotics work, the open questions were documentation requirements, key management protocols and acceptable cryptographic implementations. Former FDA reviewers clarified those expectations through encryption architecture reviews and threat modeling workshops, then identified improvements to the cryptographic implementation and submission materials before FDA review.
FDA now enforces completeness through eSTAR, which is required for 510(k) submissions. There is no separate cybersecurity refuse-to-accept review; eSTAR itself is the gatekeeper. Gaps found during substantive review lead to an additional-information request that puts the 510(k) on hold until you respond. Each extra round adds review time, so a complete first submission is usually the fastest path to clearance.
