Data security on premisis premium solution

Hi all,

I have a security question regarding best practice on my PowerBI solution.

Our setup as if today; Data Warehouse to Power BI by a dataset.

We are going to have 150+ reports, where some users should see all, some a bit and some only 1 or 2 reports.

1000+ workspaces and filters in reports is not an option 😉

Should I go with RLS, AD or a 3. option?

Thanks in advanced.
