External access
Vendor Access Review
External access grows quietly. Agencies, contractors, software tools,
billing services, and temporary collaborators can keep more reach than
a small team realizes.
Inventory
List where vendors can touch money, data, content, or identity.
Start with practical categories: shared inboxes, payment systems,
analytics, cloud storage, CMS accounts, ad platforms, code repositories,
social channels, and automation tools. The review becomes manageable
when you look at concrete systems instead of “all vendor access.”
Ownership
Every external access path should have an internal owner.
Somebody on the internal team should know why the access exists, what
role it supports, and when it should end. That owner does not have to
manage daily work, but they should be able to approve or remove access.
Review
Check whether access is role-based or just historical.
Many access grants stay in place only because they were useful once.
The goal of a review is not suspicion; it is to reduce old permissions,
shared credentials, and unnecessary admin privileges.
- Does this vendor still need access today?
- Is the permission level still proportional?
- Is the access tied to a personal email instead of a managed account?
- Would the team notice quickly if this access was abused or misused?
Cadence
Run smaller reviews on a schedule instead of rare giant audits.
A quarterly pass across high-value systems is often enough for a small
operation. The review works best when it is light, repeatable, and tied
to role changes, vendor changes, and offboarding events.
