How do you mitigate a ransomware attack?

Mitigation spans before, during, and after an attack: harden and patch systems, segment networks, enforce MFA and least privilege, and maintain immutable, tested backups beforehand; isolate affected systems and preserve evidence during; and recover from a proven clean point afterward.

The step most often missed is verifying that backups are actually clean and recoverable. Elastio closes that gap by continuously hunting inside backup and replicated data and identifying the last known clean recovery point, so mitigation does not end with a restore that quietly reintroduces the threat.
