Free External Attack Surface Scan
Discover every internet-facing asset an attacker can see — subdomains, open ports, expired certificates, and exposed services — with a free external attack surface scan.
What this scan checks
Unknown and forgotten subdomains and IP addresses
Open ports and exposed services on your perimeter
Expired, weak, or misconfigured SSL/TLS certificates
Dangling subdomains at risk of takeover
How it works
Enter your domain
Start with a single domain. ScruteX discovers the rest of your external footprint automatically.
We map your surface
We enumerate IPs, subdomains, ports, and technologies exposed to the internet, then check each for common exposures.
See what's exposed
Get a prioritised inventory of your attack surface with the highest-risk exposures flagged for action.
This free scan is a taste of Vulnerability Insights, part of the ScruteX CTEM platform. Explore all free tools or see the full platform.
