The Challenge
A radiotherapy device manufacturer needed a secure, efficient way to protect communication between treatment planning software and the device itself. Key challenges included:
- Manual & outdated provisioning – Security key management relied on labor-intensive, error-prone processes.
- Performance constraints – Limited memory and processing power made integrating security features difficult.
- Vulnerabilities to cyber threats – Outdated protocols left patient data and system communications exposed.
- Complex infrastructure – Secure communication was required across two networks and 25 nodes without costly re-engineering.
- Regulatory compliance – Meeting evolving FDA cybersecurity requirements without disrupting clinical operations was critical.
