AI-driven anomaly detection; production references still building.

Vendor Trust is scored independently of product quality. A great product from an unfair vendor still earns a low trust score.

Trust is separate from product quality. A vendor can ship great software and treat customers badly — or vice versa. We score the two independently.
8.0+/10: strong. Few concerns at renewal or procurement.
6.5–7.9: mixed. Negotiate hard on the lowest dimensions; monitor across the contract term.
5.0–6.4: cautious. Add explicit mitigation language to the master agreement.
Below 5.0: concerning. Treat this as a contracted-risk evaluation, not a product-fit evaluation.
Updates: we re-verify scoring quarterly. Material trust events (acquisitions, breaches, leadership change, hostile contract terms) get logged on the timeline above.
