Hello, I have a client site we want to migrate to Cloud that currently has a whitelist of IP addresses to allow access to a list of urls. Does anyone know how to achieve this in Cloud or is it not currently possible? All I can find is the Public Access docs that are for the entire site not page level specific.

You could use some code middleware that does the IP filtering for you on application level.

Public access is for any page (plus descendents of that page, if that helps). Otherwise, yes, some middleware will do..
