Deployment best practices

Glean mirrors and enforces your enterprise access controls, but a successful rollout also requires thoughtful planning and ongoing governance. This guide walks through security best practices for each deployment phase, from initial setup through long-term operations.

Pre-deployment

Establish a formal ownership model

Assign the following roles before rollout:

Executive Sponsor: Owns business outcomes and ROI
Product Owner: Owns KPIs and the operating model
Glean Admin: Handles configuration, connectors, and tier-1 support
Security and Compliance Lead: Oversees policies, audit logs, and role reviews
Line-of-business champions: Represent functional teams and drive adoption

See About RBAC and Administrator roles.

Integrate identity securely

Configure SSO (OIDC or SAML) and SCIM for automatic deprovisioning
Enforce conditional access where possible to restrict service account activity to trusted IPs

See Entra ID (OIDC) and Managing users.

Plan sensitivity scans with Glean Protect

Create a test user group for any new datasources so you can validate crawl configuration and run sensitivity scans before expanding access to all users.
After indexing completes for the test group, run Glean Protect scans with auto-hide enabled to catch overexposed documents (for example, PII shared with "Everyone") before broader rollout.

See Manage policies and About sensitive findings.

Deployment phase

Controlled launch

Onboard users in stages
Validate mirrored permissions in a small, monitored environment

See Connectors and Excluding content.

Lock down administrative functions

Monitor access to powerful features in audit logs

See Audit logs.

Security gates at expansion

Before expanding access to new user cohorts, review Glean Protect scan results and confirm that auto-hide has addressed any policy violations
For new datasources, onboard to a test group first, allow indexing to complete, and run Glean Protect scans before expanding access

See Manage policies and View sensitive findings flagged by policies.

Validate permissions and audit logs

Confirm that permission mirroring reflects source system changes, especially during offboarding
Stream logs to your SIEM (for example, Splunk or Chronicle) for anomaly detection

See Audit logs and Troubleshooting search.

Test governance enforcement

Simulate edge cases (for example, revoked access in SharePoint) and confirm that changes are reflected in Glean

Post-deployment and remediation

Enable auto-hiding with Glean Protect

Instantly hide documents that violate policies (for example, PII in public folders)
This reduces the blast radius while you remediate the source data

See Managing result visibility.

Schedule recurring scans

Run sensitivity scans quarterly or more frequently to surface new exposures across evolving content

See Guide to sensitive findings.

Protect+ for threat defense

Detect and block prompt injection and jailbreak attempts
Enforce context-only LLM access via RAG to prevent output leakage

See Protect+ quickstart.

Periodic access and privilege reviews

Validate RBAC assignments and Super Admin role justifications
Audit who has access to sensitive moderation tools

See About RBAC and Administrator roles.

Formal change management for new sources

Before expanding a new datasource to all users, complete the following:

Onboard the datasource to a test group and allow indexing to complete
Run Glean Protect scans with auto-hide enabled and review findings
Complete a security review
Obtain Admin sign-off

Integrate with Microsoft Purview

Use Microsoft Purview to enforce label-based indexing restrictions
Validate API behavior independently through the Purview Compliance Portal

See Permission and security controls for SharePoint.

Key tools and controls

Tool	Purpose
Glean Protect	Sensitive content detection, auto-remediation, and centralized dashboard
Auto-hiding	Prevents policy-violating content from appearing in search and AI before the root cause is resolved
RBAC	Enforces strict access separation and least privilege
SIEM integration	Enables alerting and investigation through enterprise monitoring tools
Conditional access	Restricts connector credentials to trusted IPs to mitigate broad permissions
SCIM	Ensures near-real-time user deprovisioning for dynamic access management

Roles and responsibilities

Role	Key responsibilities
Executive Sponsor	Aligns Glean to ROI, secures resourcing
Product Owner	Owns internal roadmap, KPIs, datasources, adoption
Glean Admin	Daily configuration: datasources, test groups, visibility, roles, features
Super Admin	Assigns sensitive content roles; access restricted by policy
Sensitive Content Moderator	Builds policies, triages findings, auto-hides, partners on remediation
Agent Creator	Builds agents
Agent Moderator	Approves agent sharing, enforces guardrails
Security and Compliance Lead	Reviews audit logs, SIEM pipelines, alerts
Datasource owners	Manage credentials, redlists/greenlists, and permission alignment
DevSecOps / Platform	Monitor configuration drift, audit logs, WAF/IDS, support SIEM and IP controls
