Geopolitical read Glasswing access has followed Five Eyes alignment. The United States, United Kingdom, and Australia each have named participants or reported government use. The European Union has been excluded from the launch cohort and has begun regulatory response through financial and cybersecurity authorities. China is actively blocked. This distribution is not incidental: Glasswing terms require compliance with U.S. export controls, which categorically bars entities subject to Chinese government oversight.
