Distinguish certificate problems from protocol configuration: whether TLS 1.2/1.3 handshakes succeed, what cipher is negotiated and which ALPN protocol is selected.
TLS configuration
Probe TLS 1.2 and TLS 1.3 support from a DotMoose diagnostics node, record the negotiated cipher and ALPN, and keep certificate and HTTP protocol signals together.
Result
Distinguish certificate problems from protocol configuration: whether TLS 1.2/1.3 handshakes succeed, what cipher is negotiated and which ALPN protocol is selected.
This is intentionally not an exhaustive cipher-suite scanner and it does not attempt downgrade attacks. HTTP/3 is not claimed merely because Alt-Svc advertises h3.
DotMoose records only the tool name and a coarse success/error outcome for marketing analytics. Active server diagnostics use bounded operational security logs without placing the entered domain, IP, URL, DNS answer or report contents into marketing telemetry.
