What Our Users Say

"SubDoms found 340 subdomains for our main domain that we did not know existed. Three of them were vulnerable to takeover. We remediated them the same day. This tool literally prevented a security incident before it happened."

"I use SubDoms as the first step in every bug bounty engagement. The CT log integration catches subdomains that Amass and Subfinder miss. The export to JSON feeds directly into my recon pipeline. It has directly contributed to several critical findings worth over $15,000 in bounties."

"The monitoring feature is a game-changer for our security operations center. We get alerted within minutes when a developer spins up a new staging environment or when a marketing team creates a landing page on a new subdomain. No more shadow IT surprises."

"We manage DNS for over 200 client domains. SubDoms API integration into our management platform gives us automated subdomain inventory for every client. The bulk scanning feature saves our team hours every week compared to running individual scans with command-line tools."

"As a penetration testing company, we need reliable reconnaissance tools. SubDoms has become an essential part of our external assessment methodology. The depth of results from combining CT logs, passive DNS, and active enumeration in a single interface is unmatched."

"I teach a cybersecurity course at a university and I use SubDoms in my DNS security lab. The free tier gives students hands-on experience with real subdomain enumeration without needing to install complex tools. The interface is intuitive and the results are educational."

"During our acquisition due diligence process, we used SubDoms to audit the target company's DNS infrastructure. We discovered 47 forgotten subdomains, including two running vulnerable WordPress installations. This finding directly impacted our risk assessment and negotiation."

"The wildcard DNS detection is superb. We had been getting millions of false positives from other tools because our CDN uses wildcard records. SubDoms correctly identified and filtered the wildcard responses, giving us only the real subdomains. Finally, accurate results."

"We integrated SubDoms into our GRC platform for automated compliance checks. The continuous monitoring provides evidence of asset inventory completeness for our SOC 2 audit. Our auditors were impressed with the level of detail in the exported reports."
