Auto-Remediate AWS Incidents

 Auto-remediation is a triggered response to a policy violation, and it applies to AWS issues.  Auto-remediation is an automated approach to security, applying the appropriate response to a vulnerability in your S3 deployment. It ensures a high level of functionality by continuously monitoring risks and it automates issue remediation. When a policy violation occurs, this instant remediation reduces the window of malicious opportunity.

NOTE: Skyhigh CASB requires write/update permissions in AWS to implement Auto-remediation.
