API / Venafi Interview questions
What is Venafi Trust Protection Platform (TPP)?
Trust Protection Platform, or TPP, is Venafi's self-hosted machine identity engine — the on-premises (or self-managed cloud) product now sold as CyberArk Certificate Manager Self-Hosted, and referred to as "Trust Protection Foundation" in some newer documentation.
TPP holds a hierarchical tree of policy folders, each defining which certificate authority to use, key algorithm, validity period, and approval rules for the certificates issued underneath it. It talks to public and private CAs, discovers certificates already deployed across the network, and orchestrates renewal directly onto endpoints like IIS servers, F5 load balancers, and NetScaler appliances.
It exposes a REST API under two paths — /vedauth for OAuth token issuance and /vedsdk for the underlying certificate operations — which is what tools like VCert, Terraform, and Ansible integrate against.
