• Device Certificate.

1. Device Certificate is valid for 90 days since generating.
2. The Firewall device will check nightly and automatically renew its certificate 15 days prior to the expiration of the existing certificate.
3. If the automatic renewal is failed and the device certificate expires, the customer needs to go through the certificate onboarding process again as described in Administrator's Guide.
