Cloudinary security - what options do you use to secure images?

What security options should we use in Cloudinary? I had an audit of my app, and data leakage from the images was picked out as being an issue that needs to be fixed. In the Cloudinary settings there is a Security area… mine is basically blank right now. Has anyone looked at this? Thanks!

Assuming “referrer” is directly what I’m thinking of, you can put the Glide links you use for image transformation in there to make sure it’s only used in your apps.
