Vendor Offboarding Checklist: Security Playbook | Wenspiredata

Vendor offboarding is the coordinated process of removing a third party’s access, credentials, data, devices, integrations, and operational dependencies when a contract, project, individual assignment, or approved access window ends. A secure process must cover both human and machine identities across IT, cloud, OT, and industrial environments—not just disable one user account. This vendor offboarding checklist gives security, IT, procurement, legal, and operations teams a repeatable way to revoke access, preserve evidence, and verify that no usable pathway remains.
