Vendor Security Review process diagram

This is a worked example. Wavelength built the diagram below from the description on this page. Nobody drew it by hand.

What was said

Procurement submits a vendor request when a new supplier is needed. Security sends the vendor a security questionnaire. The security team rates the vendor's risk. If the risk is high, legal reviews the data processing agreement. If the risk is low, the vendor goes straight to approval. Legal approves or flags redlines in the DPA. Once approved, the vendor is added to the approved vendor register.

The diagram

Hexagons are systems. Cylinders are data stores. Diamonds are decisions. Rounded orange boxes are people and teams. A dashed amber arrow is a link the AI inferred. Pink arrows are decision branches. Blue arrows move data.
