What could be a reason for traffic being allowed by the policy despite antivirus settings?

The reason traffic might be allowed by the policy despite antivirus settings could stem from the policy configuration not effectively blocking certain types of traffic. Even when antivirus settings are in place, if the policy is not explicitly designed to intercept and block specific threats or traffic types, it may fail to enforce the intended protections.

For example, if a policy does not cover certain protocols or applications that could potentially transmit malicious content, traffic from those avenues would still be permitted. This highlights the importance of regularly reviewing and updating policy configurations to ensure all potential vectors for threats are addressed.

Other options could refer to issues such as the need for an update or exemptions that may influence the policy's enforcement, but the core reason here involves the capabilities and specifics of the policy configuration itself not aligning with the desired security outcomes.
