Graded A- on resilience. In Vannus's assessment it builds its own AI model — builds its own AI or is not captured by any single model provider.
Claude Opus 4.8 was trained on data up until January 2026.
Vannus grades Claude 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 →
