Does Glean train on your data?

Yes

Glean · Search

No. Glean does not train its models on your content by default, and its business tier (Enterprise (single-tenant or self-hosted deployment; BAA and DPA available)) keeps your data out of training.

What we checked

This assessment separates the consumer product from any business plan. It uses the vendor documents linked below; an unverified item is not a pass.

Default data training: No by default; Zero-retention agreements with model providers mean your data is never stored or used for model training.
Business-tier training: No by default; Enterprise (single-tenant or self-hosted deployment; BAA and DPA available) is the business tier recorded for this profile.
Training control: Not verified; No reliable training opt-out was confirmed in the sources reviewed for this profile.

Practical risk: Glean says it never uses customer data to train models thanks to zero-retention agreements with model providers, offers single-tenant and regional (incl. EU) deployment, and will sign a HIPAA BAA. ISO 27001 status was not independently verifiable from its public pages.

How to make a decision

Check the precise account tier, written contract and intended data before approving Glean. A security certification, DPA or setting can apply to only part of a vendor's service. Keep the source links with your supplier review and revisit them when the vendor changes its terms.
