What is Subdomain Lookup?
Subdomain Lookup allows you to identify all subdomains associated with any given domain name. With the aid of a database that’s updated daily, increasing by more than 1 million subdomains daily, we provide the most comprehensive and up-to-date information on all subdomains related to a given domain name in a convenient and unified format.
Our subdomain scanner tool lets you:
Enrich cybersecurity research
Attackers are known for using tons of subdomains to evade detection. Identify all the components of their infrastructure for more in-depth investigation results.
Identify dangling records
Subdomains left unused or forgotten are all too often left insufficiently protected. Make sure these haven’t been illegitimately modified for use in attacks.
Catch all possible attack culprits
Not all lists of indicators of compromise (IoCs) are exhaustive. Attackers may be using more subdomains than those identified as IoCs. Find all possible attack entry points to cover all your bases.
Gain much-needed competitive advantages
One way to get ahead of the competition is by staying toe-to-toe with business rivals. Their recently added subdomains can clue you into their up and coming product and service launches, as well as the business partners they might be working with.
Boost penetration testing efforts
Identify all your network’s weakest links by going deeper than the domain level. Consider your entire infrastructure so none of your systems are left exposed to threats or risks.
