SSLyze – SSL/TLS scanning tool and Python library

SSLyze is a fast and powerful SSL/TLS scanning tool and Python library.

SSLyze can analyze the SSL/TLS configuration of a server by connecting to it, in order to ensure that it uses strong encryption settings (certificate, cipher suites, elliptic curves, etc.), and that it is not vulnerable to known TLS attacks (Heartbleed, ROBOT, OpenSSL CCS injection, etc.).

This is free and open source software.

Features include:

• Focus on speed and reliability: SSLyze is a battle-tested tool that is used to reliably scan hundreds of thousands of servers every day.
• Easy to operationalize: SSLyze can be directly run from CI/CD, in order to continuously check a server against Mozilla’s recommended TLS configurations.
• Fully documented Python API to run scans directly from any Python application, such as a function deployed to AWS Lambda.
• Support for scanning non-HTTP servers including SMTP, XMPP, LDAP, POP, IMAP, RDP, Postgres and FTP servers.
• Results of a scan can easily be saved to a JSON file for later processing.
