Security audit
SIP TLS certificate checker
Probe any SIP TLS endpoint to inspect the certificate chain, expiry, cipher suite, and trust status. Essential for Kamailio and Asterisk TLS hardening.
Probes TLS handshake on the target host. SRTP media encryption cannot be verified via TLS probe — only the signaling TLS certificate and cipher suite.
Enter a SIP TLS endpoint to inspect the certificate chain.
How it works
Three steps to results
- 01
Enter host and port
Type your SIP TLS domain and port (default 5061). The server performs a TLS handshake to retrieve the certificate.
- 02
Review the grade
Get an A–F grade based on trust, expiry, and TLS version. See the full certificate chain and Subject Alternative Names.
- 03
Fix before deploy
Address expiry warnings, weak ciphers, and untrusted chains before exposing your SIP TLS endpoint to the internet.
