Glean mirrors each source's permissions. Employees can find anything their source already lets them open, including content shared too broadly. Fix oversharing and decide which controls cover indexed content, live results, and agent actions.
When you need this
- Security or legal review asks what Glean will expose before rollout.
- Large shared drives, public Slack channels, or old SharePoint sites have never had a sharing audit.
- Agents will take write actions in Slack, the CRM, or ticketing tools.
Evaluation criteria
Permission mirroring
Does every connected source supply the permissions Glean needs?
Look forVerify that native connectors fetch permissions alongside content, activity, and identity data. Results must follow source permissions. Web history connectors index only page titles from each user's own browsing, private to that user.
Oversharing found before launch
Which sensitive content is shared more broadly than intended?
Look forReview Glean Protect's one-time sensitive-content report. For ongoing coverage, assess Protect+ weekly scans across 100+ sources and continuous scans for select connectors. Hide flagged documents from Glean. Only a Super Admin or Sensitive Content Moderator can view findings.
Live results
Which sources are fetched live and which are indexed?
Look forTrack live sources such as Slack Real-Time Search separately. Sensitive findings scans cover only content Glean crawls and indexes. They exclude data fetched live through federated APIs.
Agent access
Who can see, run, edit, and publish each agent?
Look forAssign viewer, editor, and owner access per agent. Appoint Agent Moderators by department and set the maximum sharing audience. Require approval before changes to company-wide agents go live. Glean's October 22, 2026 release (version 564) closed a permission bypass in Agent Builder. Files uploaded through the builder assistant now stay private to the uploader and no longer attach to the agent being built.
Write actions
Which agent actions change data in other systems, and who approves them?
Look forTest actions against user permissions. Require human approval before execution where needed. An employee at a regulated firm built an outreach agent but left all write actions disabled.
Data you connect yourself
Do warehouse or custom sources carry their own permissions into Glean?
Look forRebuild access controls for sources ingested through a service account. Motive relied on Glean's Slack and Docs permissions. The BI team separately built row-level access for Snowflake by org hierarchy and account ownership.
Questions to ask vendors
- Do we need Protect+ continuous scanning, or is a one-time report enough for the first wave?
- Which of our sources are indexed, and which are fetched live?
- Which audit logs cover admin changes, and where do user and agent access histories go?
- Which certifications and SOC 2 reports can we review through the Glean Trust Portal under NDA?
Red flags
- Treating permission-aware search as a fix for overshared content. It shows exactly what the source allows.
- Assuming sensitive content scans cover live, federated results.
- Company-wide agents published without an approval step.
- Warehouse data connected through a service account with no access mapping of its own.
