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
