Our Domains & Subdomains Discovery API works for nearly all top-level domains (TLDs), which now exceeds 2,864.
All the domains and subdomains that appear in the search results come from a huge database gathered for over 10 years of data crawling. The database is growing daily by an average of 1 million newly discovered subdomains.
Need to know which domains and subdomains may have ties to cybercrime? Domains & Subdomains Discovery API data can help mitigate phishing, malware-enabled, and other attacks.
Want to enhance cybersecurity solutions in development? Integrate Domains & Subdomains Discovery API into your solutions and services to better protect your customers against harmful communications and websites, vulnerability exploits, and other threats.
Even by merely examining lists of domains and subdomains, you can strengthen protection by including all suspicious entities, even those not identified as indicators of compromise (IoCs), in your blacklists to prevent possible harm.
Need a hand in getting to know your competitors better? Scrutinize their recently-created domains and subdomains to identify potential business expansion avenues. The results can be good jumping-off points for market prospecting and understanding which products are part of an organization’s tech stack, as shown by the presence of certain product names in subdomains.
Want extra protection from trademark and copyright violators? Ensure that lookalike domains cannot adversely affect your brand reputation by fooling your customers and audiences into thinking they are dealing with you. Take action against cybersquatters and fraudsters who aim to benefit from your new product and service launches, settlement initiatives, and other high-profile activities.
