This is a forward-looking ranking, not a feature checklist. Post-quantum cryptography (PQC) is arriving: NIST finalized its first standards in 2024, and browsers and CDNs are rolling out hybrid TLS that combines classical and quantum-resistant key exchange. Customer identity platforms will adopt PQC in layers over the next few years, starting at the transport layer and moving inward.

Because almost no CIAM vendor has shipped a full post-quantum stack yet, we rank on positioning: crypto-agility, PQC-ready infrastructure, standards involvement, and the resources to execute a migration. Treat every vendor claim with healthy skepticism and ask for a concrete roadmap.

Scores reflect our [10-dimension rubric](https://startwithidentity.com/methodology/) and editorial judgment about PQC positioning.
