External Attack Surface Management
See What Attackers See. From Outside In.
Automatically discover subdomains, exposed services, and internet-facing assets — the attack surface you didn't know you had.
Subdomain Discovery
Find every subdomain — even forgotten staging and dev environments exposed to the internet.
Service & Port Mapping
Enumerate open ports, running services, and technology fingerprints across your whole estate.
Continuous Monitoring
Track changes over time — new assets appear, exposures change, and you're alerted instantly.
Attack Surface Coverage
Subdomain enumeration via subfinder & passive sources HTTP probing & tech fingerprinting via httpx Open port & service discovery Forgotten dev/staging environment detection SSL/TLS certificate transparency monitoring Exposed dashboards & admin panels Attack-surface change alerts Exportable asset inventory reports You Can't Secure What You Can't See
Most breaches exploit unknown, unmanaged assets. Attack surface mapping finds them first.
