DNS-BASED RECONNAISSANCE
Your Attack Surface is Larger Than You Think
Every forgotten subdomain, every misconfigured DNS record, every decommissioned service still pointing to your domain—these are the cracks attackers exploit while you focus on the front door. DomRecon finds them before they do.
Zone Transfer Detection
A misconfigured nameserver can expose your entire network topology in seconds. DomRecon identifies AXFR vulnerabilities that hand attackers a complete map of your subdomains, internal IPs, and DNS records—the "keys to the kingdom" that most security audits miss entirely.
Subdomain Takeover
That old staging environment you decommissioned? The GitHub Pages site from a former contractor? If the DNS record still exists, attackers can claim it and serve malicious content under your trusted domain—bypassing email filters, SSL warnings, and user suspicion.
Passive & Active OSINT
We combine search engine caches, certificate transparency logs, and public DNS records with active enumeration to reveal the full scope of your external attack surface. The assets you've forgotten about are often the ones attackers remember.
"We thought we had 12 subdomains. DomRecon found 47—including three pointing to services we'd cancelled two years ago."
