Graded C- on resilience. In Vannus's assessment it has not disclosed which model it runs — acceptable, with limits worth knowing.

Not disclosed. Flippa 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.
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 Flippa 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.
