How it runs

The automated pipeline, trigger to output.

  • TriggerVendor offboarding webhook receivedHTTP webhook
  • ActionQuery all active accounts and grants for the vendor in PostgresPostgreSQLPostgres
  • LogicBranch: residual access still active vs. fully revoked
  • ActionNotify security owner of status in SlackSlack
  • OutputFile timestamped deprovisioning closure evidence to ConfluenceConfluenceConfluence

What it does

Turns a vendor termination signal into a verified, evidence-backed deprovisioning record. It opens a revocation checklist, confirms the vendor's accounts are genuinely disabled in the access inventory, and stores proof of removal for the attestation file.

When to use it

Use it whenever a third-party contract ends or a vendor is offboarded and you must prove that access was revoked within your SLA window. Closes the common audit gap where access lingers after a relationship ends.

How it works

  1. 1An offboarding webhook (from your contract or vendor-management system) triggers the workflow with the vendor identifier.
  2. 2Queries Postgres for every active account, token, and grant tied to that vendor.
  3. 3Branches: if any access is still active, it escalates; if all access is confirmed disabled, it proceeds to closure.
  4. 4Notifies the security owner in Slack with the remaining-access list or a clean-confirmation.
  5. 5Writes a timestamped deprovisioning closure record with the before/after access state to Confluence as attestation evidence.

Set it up

  6. 6
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
