Graded B+ on resilience. In Vannus's assessment it has not disclosed which model it runs — resilient — owns model IP or routes across providers.
Not disclosed. Slack 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.
Vannus grades Slack 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 →
