How to satisfy the Security guy about hosted Grafana & data connections?

I used in-house Grafana with a previous employer and found it very useful. It would be even more useful where I work now because it’s a reasonably large server estate (Windows Server). What I would like to do is get a working demo setup with Cloud Grafana. I’ve already created an account for 1 free user. However, our Security Policy is very tight and I need to be able to satisfy the Security guy that I can setup a completely secure connection for data connections. Does anyone have any info/links on this subject? eg. certificates, etc.

When you add your data source you can specify client certificates:

This will be stored in an encrypted form in the main DB, and you can never read them of the UI/API after you set them.

Thank you torkel. Hopefully this will satisfy the security guy.
