Without mastering OPA Gatekeeper, Kubernetes clusters suffer unchecked policy violations, leaving them wide open to exploits and non-compliance.
Industry data reveals 74% of container security incidents trace back to weak policy enforcement, with average breach costs hitting $4.45 million and remediation downtime averaging 280 hours per event.
DevOps teams without this expertise face 5x higher outage rates, triggering regulatory fines up to $50,000 daily and career-ending accountability for preventable failures.
Every month of delay compounds these losses into millions for the business.
