Scan all TLS/SSL services, not just HTTPS
Most SSL scanners only test websites on port 443. FairSSL's scanner can test the TLS configuration on any service and any port, from mail servers and databases to LDAP and FTP.
Web servers
- HTTPS
- port 443
Standard TLS scanning of websites and API endpoints.
- SMTP / SMTPS
- port 25, 465, 587
- IMAP / IMAPS
- port 143, 993
- POP3 / POP3S
- port 110, 995
Test TLS on mail servers using STARTTLS or implicit TLS. Verify that Exchange, Postfix, Dovecot or other mail servers have secure configuration.
Databases
- MySQL / MariaDB
- port 3306
- PostgreSQL
- port 5432
Verify TLS encryption on database connections. Critical for databases accessible over the network.
File transfer
- FTP (STARTTLS)
- port 21
- FTPS (implicit)
- port 990
Test TLS configuration on FTP servers. Relevant for hosting, backup and automated file transfers.
Directory services
- LDAP (STARTTLS)
- port 389
- LDAPS (implicit)
- port 636
Scan Active Directory, OpenLDAP and other directory services. Important for organisations with centralised authentication.
Other services
- XMPP
- port 5222
- LMTP
- port 24
- NNTP
- port 119
- Telnet
- port 23
Chat, messaging, newsgroups and other protocols with TLS support.
Any port
All protocols can be scanned on any port between 1 and 65535. If your HTTPS server runs on port 8443, your SMTP relay on port 2525, or an internal service on a non-standard port, simply enter the port in the form.
Scanner IP address
Need to allow the scanner through your firewall? Whitelist the DNS name or the current IP:
- DNS:
- scanner.fairssl.dk
- IPv4:
- 3.123.246.76
The DNS name updates automatically when the IP changes and is the recommended method.
