Find the subdomains of an internet domain and determine the attack surface of an organization.
This subdomain scanner combines multiple discovery methods and returns only valid results to help you perform extensive reconnaissance.
This tool combines passive and active discovery methods to help you research the subdomains of your target domain for all types of security testing engagements.
Each scan delivers a list of subdomains that is validated, so you don’t have to waste time with old or invalid subdomains. Scan results also include helpful recon information such as IP address, WHOIS details, location (country), OS and server information, the technology running on the server, web platform, and page title. You can even use it to find out if any of the subdomains are sitting behind firewalls (e.g. Cloudflare, Sucuri, etc.).
Subdomain enumeration is an essential part of the reconnaissance phase, enabling penetration testers and other security and IT professionals to understand how far the attack surface spreads. Subdomain tools like this one ensure the process is both fast and comprehensive.
Discover subdomains used for development, testing, and backup that make easy targets for attackers. Combine these potential entry points in a clear attack surface view to prioritize follow-up vulnerability and exploitation tests. This subdomain enumerator also helps you check clean-up and remmediation during re-tests. through a ready-to-use VPN and start your work in minutes.
A subdomain is a potential goldmine for penetration testers because it can host applications with unpatched, critical vulnerabilities, such as Log4Shell. Since the same high-risk vulnerability can often be present on multiple domains, subdomains, and applications, a meticulous subdomain scan can help you get to these valuable findings much faster.
Our subdomain finder online is a helpful tool for independent asset inventory. Use it to check if the known list of systems exposed to the Internet matches reality. The subdomain list in the report makes it easy to update internal documentation and to decommission or upgrade legacy systems.
Our Subdomain Finder does not use a caching mechanism, so it always gives you real-time results and up-to-date findings. The tool also performs the DNS resolution of subdomains instantaneously and you only see valid results.
