What action does Zscaler take when an application is classified with a risk score over 4?

When an application's risk score exceeds 4, Zscaler implements a protective measure by blocking all traffic to that application by default. This proactive approach is crucial for maintaining security and protecting users and organizations from potential threats associated with high-risk applications. By blocking traffic to these applications, Zscaler significantly mitigates the risk of data breaches, malicious activities, or compliance violations that can arise from exposure to insecure or compromised services.

This method reflects Zscaler's commitment to ensuring a secure cloud environment, enabling organizations to have confidence in their use of applications without risking network exposure. The decision to block rather than merely notify users or adjust tenant risk scores underscores the priority placed on security, ensuring immediate protection against possible vulnerabilities.
