This level applies to traffic routed through Stav.
OpenAI is at L0. Its served endpoints run on US infrastructure, and OpenAI is subject to the CLOUD Act and FISA 702, so no L1 criterion is met. L1 would require EU/EEA compute for the served endpoints.
3 criteria from L1: Customer data in the Union, Infrastructure in the Union, No coerced vulnerability silence.
Stav's own assessment against criterion registry 4.1. Indicative, not an official recognition, which only a national authority can confer. Criteria follow the proposed Cloud and AI Development Act and are expected to change. “Union” reads as EU/EEA at every rung. CADA itself still says “in the Union”: until the Act is incorporated into the EEA Agreement, a Norwegian, Icelandic or Liechtenstein route does not evidence formal Union assurance for an EU public-sector buyer. UK and Swiss providers are capped at L1.
