Aruba ClearPass Policy Manager is a network access control (NAC) solution from HPE Aruba Networking. It enforces access based on role and device type for employees, contractors and guests across multi-vendor Wi-Fi, wired and VPN networks. It supports RADIUS and TACACS+, device profiling, posture assessment, self-registration of personal devices with a built-in certificate authority, and guest access. Authentication sources such as AD, LDAP and SQL databases can be combined in a single service. ClearPass is deployed on-premises in the organisation's own network, for example as a rack-mounted hardware appliance.
HPE is headquartered in the United States, in Spring, Texas, and Aruba has been part of HPE since 2015. The vendor therefore falls under US jurisdiction, which is relevant for the CLOUD Act. Because the policy system runs in the organisation's own environment, the organisation decides where authentication and device data are stored, for example in a data centre within the EU. The software is not open source. Updates and support remain dependent on the US vendor.
