Audit Slack workspace members and offboarding
A continuously-synced roster of everyone in your Slack workspace — admins, owners, and the accounts that should have been removed when people left.
Slack holds a running record of how your company actually operates — deal terms in DMs, incident threads, candidate feedback, the offhand decisions that never made it into a doc. The membership list that can read all of it grows quietly over the years, and almost nobody audits it. People join, change teams, leave the company, and their accounts stay right where they were.
The problem isn't that Slack hides this — it's that the member directory is built for finding people to message, not for answering access questions. Who are our workspace admins? Which accounts belong to people who left months ago? Slack's own screens make you scroll and click to find out, and the answer is stale the moment you stop looking.
Outpost turns your Slack membership into something you can actually review. Connect your workspace through Slack's standard OAuth flow and Outpost syncs the full roster — every member, their email, their title, and whether they're an admin, owner, or the primary owner — while filtering out bots so you only see real people. It's the membership audit Slack doesn't give you, kept current automatically.
Catch Slack access that outlives employment
Of every system an employee touches, Slack is one of the easiest to forget at offboarding — and one of the most revealing if access lingers. A departed employee's account left active in the workspace can still hold the history of everything they were ever part of. Deactivation is a single step, but it's a step that's quietly skipped more often than anyone would like to admit.
Outpost is built to catch exactly that gap. Because it links each Slack account to the person behind it, the moment someone is marked as departed, their Slack account surfaces for review against what should have happened. Outpost also reconciles accounts that have been deactivated or have dropped out of the workspace, so you can see the difference between "we removed them" and "we meant to."
The result is a Slack offboarding story you can prove instead of assume. Instead of trusting that every leaver was removed, you get a continuously-synced view that flags the ones who weren't — before that lingering access becomes the thing you wish you'd caught.
What Outpost detects
Everything we surface from your Slack workspace.
Every workspace member
Outpost syncs your full Slack member roster with names, emails, and titles, automatically filtering out bots and the Slackbot account so you're reviewing real people, not noise.
Admins and owners
Outpost flags which members are workspace admins, owners, and the primary owner — the accounts with the most power over your workspace and its data — so privileged access is never a guess.
Deactivated and removed accounts
Outpost tracks member status and reconciles accounts that have been deactivated or no longer appear in the workspace, surfacing access that should already be gone.
Assets we track
Outpost creates and maintains these asset types from your Slack data.
How it works
1
Connect
Authorize Outpost on your Slack workspace through Slack's standard OAuth flow. Outpost reads your member roster with a read-only token — it never posts, messages, or changes anything on your behalf.
2
Discover
Outpost creates a workspace asset and pulls in every member, capturing their email, admin and owner status, and account state.
3
Monitor
The roster is re-synced on a schedule, so new members, role changes, and deactivations are tracked over time rather than checked once and forgotten.
4
Offboard
When an employee leaves, Outpost links their identity to their Slack account so you can confirm it was actually removed — not just left active in a workspace full of company history.
Frequently asked questions
Connect your Slack workspace to Outpost and it syncs every member into one searchable roster — names, emails, titles, and who holds admin or owner rights. Bots and the Slackbot account are filtered out automatically, so you review actual people without manually scrolling Slack's member directory.
Outpost keeps a continuously-synced view of your Slack members and links each account to the person behind it. When someone is offboarded, their Slack account surfaces for review so you can confirm it was deactivated — catching the ex-employee who still has access to years of internal conversations.
Yes. Outpost flags workspace admins, owners, and the primary owner on every member, so the accounts with the most control over your workspace, its data, and its settings are visible at a glance rather than buried in Slack's admin pages.
