The Challenge
Difficulties securing a surgical tool suite
A medical device manufacturer needed to secure a Surgical Tool Suite comprising three distinct devices — each with unique technology stacks, manufacturing environments, and connectivity limitations. Some devices were built in-house, others by third parties, and all operated in disconnected environments with minimal field connectivity. Challenges included:
- Provisioning in low/no connectivity environments
- Maintaining FDA clearances across diverse subsystems
- Preventing unauthorized or gray market attachments
- Meeting corporate security goals while respecting device-specific constraints
- Operating within strict performance limitations
The Solution
Our Guardian Suite
Medcrypt’s Guardian Suite offered a unified yet flexible security architecture that worked across all three devices:
- Secure provisioning and reprovisioning in disconnected environments, both in the field and during manufacturing.
- Tailored Root of Trust (RoT) for each device, supporting unique tech stacks without affecting performance.
- Unified security architecture aligning corporate policies with individual device needs.
- Optimized cryptographic implementation that respected memory and processing limitations.
- Authentication to block unauthorized accessories, maintaining safety and reliability.
The Impact
Security infrastructure unification
Guardian Suite unified the security infrastructure across a highly diverse surgical tool portfolio, enabling secure operation while meeting regulatory expectations and performance demands.
- Prevented gray market and counterfeit attachments.
- Maintained device-specific configurations within a consistent enterprise security model.
- Achieved cybersecurity readiness without redesign or revalidation.
- Preserved high performance in critical surgical environments.
