Market map · Red teaming × United Kingdom
The verified Red teaming landscape in United Kingdom.
Every AI builder headquartered in United Kingdom whose Red teaming listing is cross-referenced (L2) or higher against public sources the provider does not control. Ranked on earned proof, never paid placement.
22 verified builders qualify for this map, every one cross-referenced (L2) or higher. Order is earned: highest verification level first, ties broken by most-recent verification. A free-plan L5 provider always outranks a paid-plan L1; plan tier is never a ranking input.
Most recent verification on this map: 2026-07-07. This is a live view, the ranking updates as builders re-verify.
Choosing an AI builder? Don’t stop at the demo. Trustgent’s six-level verification scale(L0-L5) tells you how much of a provider’s claim is independently corroborated, and how ranking works explains why proof, not spend , sets the order. Work through the questions to ask a partner and the evaluation scorecard, then request verified quotes from the builders on this map.
