The Healthcare Cybersecurity Challenge
Modern healthcare systems encompass a wide array of electronic medical devices (EMDs), electronic health records (EHRs), and interconnected networks that manage everything from patient data to diagnostic tools. These systems often operate in environments with varying levels of security, making them attractive targets for cyber threats that can compromise patient safety, data privacy, and operational integrity.

Traditional security testing methods may fall short in identifying subtle and complex vulnerabilities within healthcare firmware, leaving critical gaps that can be exploited by malicious actors. The need for advanced, automated tools that provide comprehensive coverage and integrate seamlessly into existing development and maintenance workflows is essential to address these challenges effectively.
