Aruba ClearPass Policy Manager

Aruba ClearPass Policy Manager is an enterprise Network Access Control (NAC) and policy management platform designed to deliver secure, context-aware network authentication and access governance across wired, wireless, and VPN infrastructures. ClearPass serves as the central policy decision point for zero-trust network access, automatically identifying, profiling, and authorizing every connecting device—including corporate laptops, personal BYOD smartphones, and headless IoT sensors. Utilizing industry-standard protocols such as RADIUS and TACACS+, ClearPass evaluates authentication credentials against corporate directories (like Microsoft Active Directory, LDAP, and Okta) while continuously assessing endpoint health posture via agents or passive profiling. Based on rich contextual factors—such as user role, device ownership, location, time of day, and operating system patch status—ClearPass assigns dynamic access privileges, placing devices into microsegmented VLANs or enforcing least-privilege firewall rules. In the event an endpoint is compromised, ClearPass integrates with enterprise EDR, SIEM, and firewall systems to execute automated quarantine actions in seconds. Aruba ClearPass provides organizations with total visibility and granular control over network perimeters, satisfying stringent regulatory compliance standards and stopping lateral threat movement.
