SSLyze

SSLyze is a fast and powerful Python library and command-line tool for analyzing the TLS/SSL configuration of servers to identify misconfigurations, weak cipher suites, and protocol vulnerabilities. It tests for issues including Heartbleed, certificate chain problems, support for deprecated protocols like SSLv3 and TLS 1.0, and compliance with security standards. Security auditors, DevOps engineers, and compliance teams use SSLyze to validate that their TLS deployments meet organizational policies and industry requirements such as PCI DSS. Its Python API makes it easy to integrate into CI/CD pipelines and automated security scanning workflows, enabling continuous monitoring of TLS configurations across large server fleets.
