Source: kommunermedipv6.se, latest scan per country (Sept 2026). PQC = the website's TLS 1.3 handshake negotiates X25519MLKEM768 or another hybrid ML-KEM group (openssl probe); sites that still also allow TLS 1.2 are counted too. Counted per municipal domain – municipalities without a known website are not included. Hover over a row for the counts.
