API / Venafi Interview questions

What are the types of certificate authorities Venafi supports?

Venafi is deliberately CA-agnostic, so it can front almost any type of certificate authority an organization already relies on rather than forcing a switch.

CA type	Examples
Public commercial CAs	DigiCert, Sectigo, GlobalSign, Entrust
Free automated CAs	Let's Encrypt and other ACME-based issuers
Private enterprise CAs	Microsoft ADCS, EJBCA
Cloud-native CAs	Google Certificate Authority Service, AWS Private CA

For CAs without a native connector, Venafi provides an Adaptable CA framework — a script-driven interface that lets an integrator wire up an arbitrary CA's enrollment API in days rather than waiting on a vendor-built plugin.

Take quiz

Is Venafi restricted to only working with one specific certificate authority? Yes, it only works with DigiCert

✗ Try again — Venafi is CA-agnostic across many providers.

No, it supports public, private, and cloud-native CAs through built-in connectors

✓ Well done! CA-agnosticism is a core design goal.

Yes, it only issues self-signed certificates

✗ Try again — it integrates with real CAs, public and private.

How does Venafi integrate with a CA that has no pre-built connector? It cannot integrate with that CA at all

✗ Try again — the Adaptable CA framework covers this gap.

It requires switching to a different CA entirely

✗ Try again — that's what Adaptable CA avoids.

Through the script-driven Adaptable CA framework

✓ Well done! It lets integrators wire up arbitrary CA APIs.
