Operationalizing Day Minus Seven: The Cloud-Native ROC

The article introduces the concept of a Risk Operations Center (ROC) as a necessary evolution for cybersecurity teams facing AI-driven threats. It argues that traditional risk management models are insufficient due to the speed at which AI can discover and exploit vulnerabilities, especially in cloud environments. A ROC, powered by platforms like Qualys Enterprise TruRisk Management (ETM), aims to unify disparate security findings, hyper-prioritize risks based on exploitability and business impact, and enable autonomous remediation to keep pace with attackers.
