## What it is
A command-line reference client for the SSL Labs APIs, written in Go, for automated and bulk SSL/TLS server assessment. It scans hosts against Qualys SSL Labs and outputs results as JSON, including grades.

## Use cases
- bulk scan ssl/tls configurations of many hosts
- automate ssl labs server grade checks in ci
- monitor certificate and tls weaknesses across domains
- get  output of ssl server assessments for reporting
- check tls server grade from the command line

## When to choose
- you need scripted or scheduled SSL Labs assessments of many hosts
- you want machine-readable JSON results from SSL Labs
- you want the official reference client for the SSL Labs API

## When to avoid
- you need local/offline TLS scanning without the SSL Labs cloud service
- you need a GUI or interactive scanning experience
- you cannot accept SSL Labs API usage terms and rate limits

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: security, cli, developer-tools
- domain: security, developer-tools
- platform: windows, cli, cross-platform
