Your next-generation firewall can leverage
cloud services such as Device Telemetry and IoT. To do this, you
must install a device certificate to successfully authenticate the
firewall with the Palo Alto Networks Customer Support Portal (CSP)
to leverage these cloud services. The circumstances under which
a device certificate is required will differ from feature to feature,
so install a device certificate only if the feature's setup documentation
tells you that this needs to be done.
