What is a cloud provider questionnaire?

To evaluate a cloud provider, prior to engagement, it is very common to send the cloud provider a questionnaire, with all the topics your team believes need to be asked, to get familiar with the cloud provider.

Mature cloud providers have, most likely, shared information about their compliance and security controls.
