About:
Tlsx is a high-performance command-line tool designed for TLS-based information gathering and security reconnaissance. It efficiently probes TLS endpoints to extract certificate details, cipher suites, and other TLS-specific data. The tool offers extensive customization for security professionals conducting network assessments and infrastructure discovery.
Key Features:
  • Fast and concurrent TLS scanning engine
  • Comprehensive certificate and cipher suite enumeration
  • Multiple output formats including JSON and CSV
  • Customizable TLS handshake parameters
  • Support for bulk target processing
Use Cases:
  • Security auditing of TLS configurations across infrastructure
  • Certificate transparency monitoring and validation
  • Network reconnaissance and service discovery
  • Compliance checking for TLS security standards
Alternatives:
  • nmap – General-purpose network scanner with TLS capabilities, less specialized for TLS enumeration
  • sslscan – Similar TLS scanning tool, but tlsx offers better performance and modern cipher support
  • testssl.sh – Comprehensive TLS testing suite, but tlsx is faster and more focused on data collection
