SSL/TLS Exposure Check
Scan any public host for outdated protocols, untrusted certificates, and TLS misconfigurations that leave your connections open to interception and downgrade attacks. Enter a hostname to see the protocol support, certificate trust, revocation status, and cryptographic strength it advertises.

What You Need to Know
Understand the Checks
SSL/TLS Exposure Check connects to a public host over TLS and inspects exactly what the server advertises — the protocol versions it will negotiate, the certificate it presents, and the connection-hardening settings around them.
Weak configurations here are frequently the easiest path in: they let an attacker on the network path intercept, downgrade, or impersonate a connection that both sides believed was secure.
Assess Your Exposure
A finding doesn't always mean active compromise, but it does mean the configuration diverges from current best practice. Review exposure across:
Legacy protocol support (SSLv2/SSLv3, TLS 1.0/1.1)
Self-signed or expired certificates
Missing OCSP stapling or revocation checks
Weak signature algorithms or short RSA keys
Missing SANs or hostname mismatches
Take Action
ThreatMon recommends:
Disabling SSLv2/SSLv3 and TLS 1.0/1.1
Replacing self-signed or expired certificates with a trusted CA
Enabling OCSP stapling and secure renegotiation
Moving to SHA-256+ signatures and 2048-bit+ keys
Ensuring SANs cover every hostname the certificate serves
ThreatMon Intelligence
ThreatMon's platform extends this check into continuous monitoring, so drift and expiring certificates are caught before they become incidents. Our intelligence surfaces:
Continuous TLS and certificate monitoring
Expiry and misconfiguration alerts
Correlation with your broader attack surface
