Palo Alto Networks uses proprietary technologies to identify and control traffic sources regardless of IP address or network segment. These technologies include:
* User-ID (A): This technology maps IP addresses to user identities, allowing policies to be enforced based on user or group identity rather than just IP addresses. This is especially useful in dynamic environments where IP addresses can change frequently.
* Device-ID (A): This technology helps to identify and control devices accessing the network. It provides visibility into which devices are on the network and ensures that policies can be applied based on device type and identity.
