DIGIHEALS is ARPA-H’s Digital Health Security Initiative, focused on protecting health care systems, facilities, devices, and patient information from cyberattacks. The program funds work addressing vulnerabilities in health care data and infrastructure, including automated medical-device patching, ransomware response, cyber reasoning, and secure electronic health record handling. Its projects aim to help prevent attacks and reduce their effects when they occur, so health care organizations can maintain patient care. DIGIHEALS awardees have also demonstrated approaches to restoring hospital connectivity during a simulated ransomware incident.
