{"id":8204,"library":"google-cloud-securitycenter","title":"Google Cloud Security Command Center","description":"Google Cloud Security Command Center (SCC) is a security and data risk platform that helps you prevent, detect, and respond to threats across your Google Cloud assets. It identifies security misconfigurations, surfaces suspicious activity, and provides actionable recommendations.
