Tells youA critical_finding event goes to the channels subscribed to it: e-mail, Slack, Teams, a webhook, Jira, GitLab or GitHub.
RefusesWith a policy that blocks critical findings, a pod with this image is refused at admission, a rollback to it included. Pods already running are not evicted.
RecordsEach decision is recorded with the policy that ran and its hash, then sealed under a signed checkpoint.
