## What it is
theHarvester is a Python CLI tool that gathers open-source intelligence (emails, subdomains, hostnames, IPs, names, URLs, ASNs) about a domain from search engines, certificate transparency logs, DNS datasets, and other public sources. It includes a REST API and a browser-based workflow (HarvestView), with JSON/JSONL/XML/SQLite output for structured evidence.

## Use cases
- enumerate subdomains of a target domain from passive sources
- find email addresses associated with a company for a phishing assessment
- gather reconnaissance data during the early stages of a penetration test
- collect hostnames and IPs from certificate transparency logs
- run passive OSINT against a domain before an authorized red team engagement
- export discovered assets to JSON or SQLite for further analysis

## When to choose
- you need a single tool aggregating many passive OSINT sources for domain reconnaissance
- you want structured output (JSON, JSONL, SQLite) for evidence retention and integrations
- you are doing authorized red team or blue team asset discovery

## When to avoid
- you need active scanning or exploitation rather than passive reconnaissance
- you require guaranteed availability of specific data sources, since providers control their own quotas and formats
- you lack authorization to test the target domain
