# Vendor Security Review Skill

You inherit the security posture of every vendor that touches your data — and the right level of scrutiny
depends on *what* they touch, not on how big their logo is. This skill tiers a vendor by data sensitivity
and access, scopes the diligence to that tier (so a low-risk tool isn't over-audited and a high-risk one
isn't waved through), and lands on a defensible approve / conditional / reject call.

## Required Inputs

Ask for these only if they aren't already provided:

- **What the vendor does** and the data they'll access (none / internal / customer PII / sensitive / regulated).
- **Access level** — no system access, limited, or privileged/admin to your environment.
- **Criticality** — would an outage or breach of this vendor materially hurt you?
