Identity security & governance for Slack
Your identity provider controls who signs in to Slack, not which channels guests and apps can see. Oleria maps every guest membership, app token, and Slack Connect relationship down to the channel level so you can meet compliance requirements without manual exports.

Key Takeaways
- Slack identity providers control who signs in but not which channels guests and app tokens can see, meaning single-channel guests, Slack Connect partners, and third-party app integrations retain access to internal conversations long after their purpose ends.
- Oleria governs Slack down to the channel level across Enterprise Grid and standalone workspaces, mapping every guest membership, app token, and Slack Connect relationship into a continuous identity security graph with usage data layered on top.
- Channel-level access reviews based on actual activity replace manual Slack admin exports, enabling bulk removal of dormant guests and revocation of unused app tokens without disrupting active collaboration.
- Oleria generates the audit evidence needed to satisfy compliance requirements around sensitive Slack channels, guest access, and non-human app tokens that Slack's native reporting cannot produce.

Automate workspace privilege reviews, govern Slack Connect guest access, and secure non-human app tokens
Oleria's Slack integration gives security teams one view of who can access Slack workspaces and channels, how they got that access, and whether they still use it. It covers Slack Enterprise Grid and standalone workspaces.
Your identity provider controls who signs in to Slack, but not which channels, guests and apps can see your conversations. Oleria brings Slack identity governance down to the channel level, so you can meet compliance requirements and protect sensitive discussions without spreadsheet reviews.
Why is Slack access so hard to govern?
- Guests outstay their welcome. Single-channel guests, multi-channel guests and Slack Connect partners keep access to internal conversations long after a project ends.
- Apps hold quiet power. Third-party apps, custom bots and incoming webhooks hold workspace scopes that bypass user-level multi-factor authentication (MFA).
- Admin rights run wide. Primary Workspace Owners, Workspace Admins and Org Owners hold broad authority over settings, data exports and private channel discovery.
- Access follows people around. Users who change departments collect standing access across Enterprise Grid workspaces without channel cleanup.
What Oleria shows you in Slack
How security teams use Oleria with Slack
- Pass SOC 2 and ISO 27001 access reviews. Replace manual workspace CSV exports with audit-ready reports that map every user and guest to their exact channels.
- Offboard external guests on time. Find contractors and Slack Connect partners who still have access to internal channels, then remove them.
- Rein in apps and bots. Discover third-party apps and bot integrations with broad workspace permissions and restrict the scopes they do not need.
- Clean up dormant access. Flag inactive accounts, stale guest profiles and unused private channel memberships using historical audit logs.
How does Oleria connect to Slack?
Oleria connects with a standard user token or app integration that uses read-only administrative scopes, such as channels:read, users:read and auditlogs:read. It does not need full Primary Workspace Owner control. Once connected, Oleria discovers your Slack access continuously, so the picture stays current as people, guests and apps change.
Slack identity governance FAQs
What is Slack identity governance?
Slack identity governance is the continuous discovery, review and management of who can access Slack workspaces and channels. It covers workspace roles, channel memberships, guest accounts and app bot tokens. Oleria automates Slack identity governance so security teams can enforce least privilege and stay ready for compliance audits.
How do you find over-privileged guests and users in Slack?
Oleria finds over-privileged Slack users and guests by comparing workspace roles, channel access and app permissions with real-time Slack audit events. Users and external guests who keep access they do not actively use are flagged automatically. Security teams can then revoke Slack access that has gone unused for 30, 60 or 90 days.
Does Oleria need Primary Workspace Owner permissions in Slack?
No. Oleria does not need Primary Workspace Owner control to integrate with Slack. Oleria connects using a standard user token or app integration with read-only administrative scopes, including channels:read, users:read and auditlogs:read. Those scopes let Oleria discover Slack access continuously without full owner rights.
How do you audit Slack Connect and guest access?
Oleria audits Slack Connect and guest access by correlating single-channel guests, multi-channel guests and external Slack Connect users across every enterprise workspace. Oleria then shows which internal channels each outsider can still reach. Security teams can offboard contractors and Slack Connect partners whose access should have ended.
