Cyber recovery works by isolating, identifying, and recovering compromised data and systems after a cyberattack. By deploying pre-packaged data vaulting solutions like the Zerto Cyber Resilience Vault, organizations can protect their most critical assets in an isolated environment, ensuring that recovery is possible even if the main system is compromised. It involves scanning systems for vulnerabilities, restoring data from secure backups, and validating that the restored environment is secure.
