xwllz is a CLI for discovering, monitoring, and reporting on your own external
attack surface. It maps the domains, subdomains, IPs, services, certificates, and
exposure points an attacker can reach — so blue teams can see their perimeter before
attackers do.
xwllz is pure Python by default — no system binaries required. It detects
optional accelerators (nmap, masscan, rustscan, nuclei, httpx, dnsx,
dig) on your PATH and uses them automatically when present, and falls back to
its built-in engines otherwise. Data is stored in SQLite.
Each run produces a snapshot. xwllz monitor re-runs discovery and diffs
against the previous snapshot, showing you exactly what's new, changed, or
removed across your perimeter.
pipx install xwllz
xwllz init acme --domains example.com,corp.example.com
xwllz discover acme
xwllz monitor acme # re-scan and show what changed
xwllz report acme --format mdKeyless by default: crt.sh (certificate transparency), DNS (A/NS/MX/SPF/DMARC/DKIM), HTTP probing, TLS/cert inspection, socket port scans.
Optional keyed enrichment (set env vars to enable):

| Shodan | SHODAN_API_KEY |
| SecurityTrails | SECURITYTRAILS_API_KEY |
| Censys | CENSYS_API_ID, CENSYS_API_SECRET |

| URLhaus | URLHAUS_API_KEY |
| VirusTotal | VIRUSTOTAL_API_KEY |
