Palo Alto hardware firewalls use an onboard hardware TPM chip to uniquely secure and authenticate the appliance identity. When requesting a device certificate, the firewall submits its unique TPM public key to Palo Alto’s cloud servers. The cloud matches this request against its manufacturing registration database. The validation fails due to three main issues:
