Venafi automates protection for machine identities, which all organizations rely on to keep communications between machines secure and private. Venafi generates the machine identity intelligence necessary to automatically safeguard the flow of information to trusted machines and prevent communication with untrusted ones - all at machine speed and scale.
We use Venafi for PKI certificates.
Automating anything, whether on-prem or cloud, is possible.
The feature that I have found most valuable is their certificate discovery.
