About This Tool

TLS Inspector analyzes remote servers’ TLS configurations, certificates, and cipher suites to identify misconfigurations, expired certs, and weak protocols. It accepts domain, port, and optional test settings and returns structured results.
Conceptually, the tool performs simulated handshakes for configured TLS versions, retrieves the certificate chain, validates against a trusted store, and reports handshake timing. Outputs include protocol version, cipher suite, certificate details, and chain status.
Target users are security engineers, DevOps, and IT admins responsible for server hardening, remediation tasks, and compliance. Its differentiator is a structured data model with clear risk indicators, advanced options (OCSP, ALPN, JA3), and machine-consumable outputs suitable for automation.

How to Use

Provide inputs: host, port, timeout.
Optionally configure test_versions, enable ocsp, alpn, or ja3 fingerprint.
Run inspection to collect TLS metrics and certificate data.
Review outputs for version support, chain validity, and cipher strength.
Use results to remediate misconfigurations or renew expiring certificates.

Frequently Asked Questions

Find Quick Answers

What data does TLS Inspector collect?

It collects TLS protocol versions, cipher suites, certificate subject/issuer, validity periods, SANs, and handshake timing. Optional data includes OCSP status and JA3 fingerprint when enabled.

Is the analysis real-time and scope-limited?

The tool performs on-demand TLS handshakes to the specified endpoint. Results reflect the current configuration and can be repeated to monitor changes.

Can it test multiple hosts in one run?

By default, each run analyzes a single endpoint. Automation or API hooks are recommended to batch-test multiple hosts and compare results.

How should I interpret results?

Look for a valid chain, TLS 1.3 support, strong cipher suites, and certificates with valid dates. Flagged weak ciphers, deprecated versions, or missing chain indicate remediation needs.
