- Organizations need to have at least one certification authority (CA) in place, which could be part of an on-premises Public Key Infrastructure (PKI) or a cloud-based PKI solution like TruU Cloud PKI
- Users should possess a client authentication certificate from a trusted PKI that has been configured on the tenant
- Only users with Global admin or Privileged Authentication Administrator roles have the necessary permissions to configure the CA
- CA requires an internet-facing URL that is accessible and has a published Certificate Revocation List (CRL)
