Applying encrypted communication ransomware prevention channels, VPNs, and multi-factor authentication can add to the security levels.

To sum it up, Blackcat ransomware puts forward an immense risk to health care providers. Yet, with proper preventive measures, the impact of such attacks can be decreased. It's time for healthcare to commit towards comprehensive cybersecurity actions to secure patient information and the smooth functioning of medical services.
