Vendor Access Control for Outsourcing
Vendor access should be intentional, limited, documented, and removable. Convenience is not a good access-control plan.
Least necessary access
Give providers the minimum access needed to perform the agreed work. That may mean read-only access, restricted folders, delegated email access, limited software roles, or temporary project accounts.
Access should match scope. When scope changes, access should be reviewed.
Named accounts and approvals
Named accounts make it easier to know who did what. Approval rules make it clear who can request or grant access. A provider should not be able to expand its own permissions without buyer approval.
For sensitive systems, keep an access register that lists user, role, reason, approval date, and removal date.
Monitoring and review
Review active accounts regularly. Look for unused accounts, shared logins, broad administrator rights, former provider staff, and permissions that no longer fit the work.
Access review is boring until it prevents a serious problem.
Offboarding
Before the relationship ends, plan how files, records, credentials, documentation, and accounts will be returned, transferred, disabled, or deleted. Confirm this in writing.
A safe exit is part of good outsourcing design, not an afterthought.
