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.
Translation and writing AI (DeepL Translator, DeepL Write, API). The imprint names 'DeepL SE', Maarweg 165, 50825 Cologne, Germany, registered at Amtsgericht Köln, HRB 104617. Vendor states "Texts are never stored or used for model training without your consent" and that it holds SOC 2 Type II and adheres to GDPR. Important nuance from DeepL's own help centre: infrastructure is hybrid — DeepL-admi
DeepL builds its own AI model. This is Vannus's assessment from its curated catalog intel.
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 DeepL 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 →
