Graded A- on resilience. In Vannus's assessment it has not disclosed which model it runs — builds its own AI or is not captured by any single model provider.
Revenue intelligence platform that records, transcribes and analyses sales calls, emails and deals. The vendor states "your data is never used to train generative models" and its help documentation states new customers can choose to store data in either US or EU data centres, both on AWS (EU region eu-west-1). The trust page names no legal entity, headquarters or country — the footer reads only "G
Not disclosed. Gong does not publish which model it runs, so this criterion is excluded and the grade rests on what we could verify. We say so rather than guess.
This is a separate question from the grade above. The grade measures resilience — whether the tool endures and whether you could leave it. This measures who can compel your data. A tool can score modestly on one and strongly on the other, and many do.
The vendor's published or catalog-recorded posture — the concrete facts this grade is built from. A full audit verifies each against the vendor's current documentation.
Vannus grades Gong against nine dimensions of trust — data sovereignty, training privacy, compliance posture, operational resilience, exit portability, and more. The heaviest criterion asks whether the tool builds its own AI or resells someone else's model; where the vendor discloses it, the grade cites the vendor's own documentation. No paid placements — scoring is walled off from affiliate revenue. See the methodology →
