Which Cisco ISE solution ensures endpoints have the latest version of antivirus updates installed before being allowed access to the corporate network?

Threat Services typically integrate with other security solutions for threat detection and response, not for initial endpoint compliance assessment.

Profiling Services identify and categorize devices on the network based on various attributes but do not assess their security compliance or software update status.

Provisioning Services manage the deployment of client software (e.g., AnyConnect) or certificates to endpoints, but they do not assess the *state* of installed software like antivirus updates.

Cisco ISE Posture Services are specifically responsible for evaluating the security state and compliance of endpoints. This includes checking for the presence and update status of antivirus software, operating system patches, and other security requirements before allowing a device full access to the network.
