# Multi-brand implementation

How do you best control folder access, row level access, column level access and user attributes without recreating Explores and Dashboards?

Hey Brian! 

I'm Izzy, the Looker Community manager. 

There's 2 components here (well, a few more, but 2 high-level ones). Folder/content access and data/query access. For content access, we recommend you turn on the "Closed System" when working with a multi-tenant setup ( https://docs.looker.com/admin-options/tutorials/access-controls#configuring_a_closed_system ). By default, that entirely isolates users from different groups/brands from one another— And it's controlled by Looker groups so you can attach it to the actual model/data permissions.

There's a whole slew of ways to do data security. You can extend explores, rather than entirely rebuilding them, and/or use access_grants (https://docs.looker.com/reference/model-params/access_grant) or even sql_always_where and user attributes, to limit access to data.  There's a bunch more options, so I might repost this question on our community forums at www.discourse.looker.com. They're more lively than the G2 comment section and you might get some interesting examples from customers.
