Everyone suggests, you approve

Get rid of tribal knowledge with Requests. Anyone with view access to data can suggest owners, missing terms, or a change to the description. It’s in your hands to approve.

Members suggest

See something missing? Make a suggestion by sending a Request.

Admins decide

Approve or reject a Request from your personalized home.

“We want to surface everything in the enterprise to the users, but restrict some data in terms of access. I have to go through a request process, but we don’t want to stop them from seeing what exists.”

Compliance-Based Access Policies

A scalable way to secure your data

Attach policies to custom classifications, like PII and GDPR

Whenever an asset is tagged as PII, your access policies are automatically applied. No more nights spent worrying if your data is in the wrong hands.

Create and scale granular metadata and data policies

Depending on the classification, select who can view and edit metadata, and who should be able to query and preview sensitive data.
