Deloitte vs TÜV SÜD: overview
Deloitte
With more than 460,000 people and roots in an 1845 London accounting practice, Deloitte has the widest reach of any firm on this list. Its AI advisory sits next to risk and regulatory teams, which helps banks, insurers, and health systems that must document how each model is governed. Deliverables tend to be thorough and heavy. Expect large teams, long timelines, and a natural path into Deloitte's own implementation work.
TÜV SÜD
TÜV SÜD traces its history to 1866 and is headquartered in Munich, with around 28,000 employees worldwide. It tests and certifies products, and its AI services assess whether a defined AI system meets EU AI Act requirements and related standards. The TÜV AI.Lab built an AI Risk Navigator that sorts systems into the Act's risk classes, and TÜV SÜD has launched a test mark for low-risk AI. It assesses instead of designing strategy, which makes it a useful independent check on someone else's work.
