Zscaler uses a proprietary technology calledZscaler PageRiskto calculate risk attributes dynamically for websites. PageRisk assesses the risk level of a website based on a variety of dynamic factors, including the site's content, reputation, and behavior, helping to identify potentially harmful or suspicious sites in real time.
This dynamic risk scoring allows Zscaler to enforce security policies more effectively, blocking or allowing access based on calculated risk rather than static lists alone. The study guide specifies that PageRisk is integral to the platform's adaptive security posture and URL filtering capabilities .
