Iden automates Slack without SCIM. Slack only offers SCIM on its Business+ plan (about 2.1x the per-seat price), so most tools either make you upgrade or leave Slack manual. Iden connects Slack through custom automation and handles provisioning, deprovisioning, and access reviews on any plan, with a full audit trail. This is the non-SCIM coverage SCIM-only tools do not have.

How Iden connects Slack

Slack does not expose SCIM or a usable provisioning API on standard plans, so Iden uses its own custom automation, built and maintained by Iden, to provision, update, suspend, and deprovision users and manage their access in Slack. Your team builds and runs nothing.

Every action is logged to an exportable audit trail for SOC 2 and ISO 27001 evidence.

Automate the full Slack lifecycle

Provisioning is the start. Iden automates the whole lifecycle for this app: joiner, mover, and leaver workflows, access requests that replace manual tickets, permission updates as roles change, and access reviews with the evidence an auditor accepts.

Onboard to Slack on day one

New hires get the right Slack access the moment HR marks them active, mapped to their role. No setup ticket, no waiting on IT.

Keep Slack permissions right as roles change

When someone changes team or title, Iden updates their Slack access and group membership to match, and strips what they no longer need.

Offboard from Slack in seconds

The moment someone becomes a leaver, Iden revokes Slack access and ends their sessions, with a timestamped record for the audit.

Turn Slack access requests into automated approvals

Requests route to the right owner, get approved in chat, and provision in Slack automatically. No manual ticket to work, no copy-paste.

Run Slack access reviews with evidence

Iden pulls who has what in Slack, sends reviewers a one-click certification, and revokes what they reject, with proof for SOC 2 and ISO 27001.

Grant time-bound Slack access

Give temporary or just-in-time Slack access that expires on its own, so standing privilege never piles up.

Find and clean up orphaned Slack accounts

Iden flags Slack accounts with no matching active employee, including shared and service accounts, so nothing lingers after someone leaves.

Right-size Slack access to least privilege

See who has more Slack access than their role needs, and pull it back to what the job actually requires.

Cut wasted Slack spend and shadow access

Governance is not only provisioning. Iden also helps you cut what you overspend on this app and catch access that never came through IT.

See who actually uses Slack

Where Slack reports last login or activity, through its API or admin console, Iden surfaces it so reviews and license clean-up target the accounts that sit idle.

Catch shadow access in Slack

Iden reconciles every Slack account against your directory to surface local logins, external guests, and accounts created outside your process, the access that never came through IT.

The Slack SCIM tax (which you skip)

If you took the SCIM route, Slack gates it to the Business+ plan (Business+: $15/u/mo (annual)), up from Pro: $7.25/u/mo (annual), about 2.1x the per-seat price across every user. With Iden you connect Slack via custom automation instead, on any plan, so this cost does not apply.

Users	Pro	Business+ (for SCIM)	SCIM tax / year
100	$8,700	$18,000	$9,300
300	$26,100	$54,000	$27,900
500	$43,500	$90,000	$46,500

How SCIM provisioning works with Iden

SCIM (System for Cross-domain Identity Management) is the industry-standard protocol for automated provisioning. Where an app supports SCIM, Iden connects to its SCIM endpoint with a token and keeps the app in sync with your source of truth in real time, the same standard integration every identity provider uses.

Create usersNew hires are provisioned into the app automatically the moment they join or are assigned a role.

Update attributesProfile, role, and department changes flow through, so the app stays aligned with your HRIS.

Deactivate and reactivateA leaver's access is suspended automatically, and restored just as fast if they return.

Push groups and membershipGroups and their members are pushed and kept in sync, so access follows role, not manual edits.

Attribute and role mappingDirectory attributes map to the app's fields. No CSV uploads, no manual data entry.

Setup is a one-time connection: turn on SCIM in the app, generate a token, and Iden runs provisioning from then on. SCIM handles the plumbing. Iden adds the governance layer on top: access reviews with evidence, time-bound and just-in-time access, and provable offboarding. Iden supports SCIM by default for every SCIM-capable app. The real question is what happens when an app has no SCIM, or gates it behind an expensive tier, which is exactly what the connector above handles.

Frequently asked questions

How does Iden connect Slack?

Iden connects Slack via custom automation. Iden builds and maintains the automation, so your team runs nothing.

Do I need the Slack Business+ plan to automate provisioning?

No. Slack gates SCIM to its Business+ plan (Business+: $15/u/mo (annual)), but Iden connects via custom automation on any plan, so you do not have to pay the SCIM tax to automate Slack.

How does Iden deprovision Slack users at offboarding?

When someone is marked as a leaver in your HRIS, Iden revokes their Slack access automatically, in seconds, and records it in an exportable audit trail for SOC 2 and ISO 27001 evidence.

Can Iden replace manual Slack access request tickets?

Yes. Slack access requests route to the right owner for one-click approval and then provision automatically, so there is no manual ticket to work and access is granted in minutes, not days.

Can Iden grant temporary or just-in-time Slack access?

Yes. Iden can grant time-bound Slack access that expires on its own, so people get access when they need it and standing privilege does not accumulate.
