External Attack SurfaceNew
Maps and monitors your complete external attack surface — domains, subdomains, open ports, exposed services, and SSL certificate health — giving you a continuous outside-in view of your organisation.
External Attack Surface
Know your perimeter before attackers do
Key capabilities
Domain & Subdomain Discovery
Continuously enumerates all domains and subdomains associated with your organisation, including forgotten assets.
Open Port Monitoring
Tracks every exposed port and service across your perimeter, flagging changes and unexpected exposures.
SSL/TLS Certificate Health
Monitors certificate validity, weak cipher suites, and TLS configuration issues before they become outages or vulnerabilities.
Technology Fingerprinting
Identifies web technologies, frameworks, and versions exposed externally to target CVE matching.
Change Detection
Alerts on new exposures or unexpected changes to your external footprint — ideal for catching shadow IT.
Asset Timeline
Historical record of every change to your external attack surface for investigation and audit purposes.
