Common Questions
What is BYCYB and what does it certify?
BYCYB (formerly LNE) is France's national metrology and testing body. In April 2026 it became the certifier for CISPE's Sovereign and Resilient Cloud Services Framework, validating 40-plus cloud services against sovereignty criteria.Source: CISPE announcement April 2026
How does the CISPE sovereign cloud badge differ from the EU SEAL framework?
CISPE's framework uses a binary Sovereign/Resilient distinction certified by BYCYB and is run by industry; the Commission's SEAL framework (part of EUCS) is EU-institution-led. CISPE explicitly criticised SEAL as a 'murky sovereignty score'.Source: CISPE announcement April 2026
Is BYCYB the same as LNE?
Yes. BYCYB is the rebranded name of LNE (Laboratoire national de métrologie et d'essais), France's national measurement and testing laboratory established in 1901.

Background

BYCYB (formerly LNE, the Laboratoire national de métrologie et d'essais) is the certification body that validates CISPE's Sovereign and Resilient Cloud Services Framework, launched on 24 April 2026. Under this framework, BYCYB certified 40-plus cloud services against a binary Sovereign/Resilient distinction, positioning the scheme as a direct competitor to the EU Commission's own SEAL sovereignty framework.

Originally established in 1901 as France's reference laboratory for measurement and testing, LNE rebranded to BYCYB as part of a strategic repositioning towards digital and data economy certification. As a state-owned enterprise under French industrial ministry oversight, it holds authority to issue conformity assessments across sectors from physical metrology to cybersecurity and data-sovereign cloud infrastructure.

BYCYB's role in the CISPE framework matters because it provides a government-backed accreditation layer for cloud sovereignty claims outside the Commission's preferred route. This creates a dual-track certification landscape in Europe: Commission-route (SEAL, EUCS) and industry-route (CISPE/BYCYB), with different criteria and different backers, complicating procurement decisions for public-sector cloud buyers.
