Microsoft Edge

Edge connection behavior depends on the browser build, platform, enterprise policies, and the peer.

Evidence to collect

1. Review the installed version and effective browser policy.
2. Run the browser check and record the negotiated group or unknown.
3. An operating-system TLS setting and a browser TLS setting may apply to different applications.

Record the scope and result

Record the tested component, client, peer, protocol, selected algorithm, and date. Keep observed negotiation, documented capability, and unknown distinct. A failed check can reflect local tooling, certificate validation, network policy, or configuration; it does not prove that all PQC is unsupported.
