There is no one-size-fits-all approach to enable security operations. Each industry has different regulations, threats, and challenges, just like every company has its unique set of requirements, risk exposure level, vulnerabilities, and Internet touchpoints. Providing reliable, tailor-fit, 24x7 security operations services and platforms requires more than hands-on expertise and state-of-the-art technologies. You need extensive and real-time visibility into the space where cyber threats originate—the Internet—to keep up with the constant changes and expansion of digital footprints.
Reactive and defensive security operations require real-time and up-to-date domain and DNS data for successful managed and extended detection and response (MDR and XDR), comprehensive vulnerability scanning, penetration testing, and red team testing. Historical Internet intelligence provides additional data points to intensify threat contextualization and investigation pertinent to Digital Forensics and Incident Response (DFIR) and related activities. WHOIS, domain, IP, and other Internet intelligence sources can supplement and enhance security operations and platforms, helping you provide specialized offerings based on a deeper understanding of your client’s environment.
Scalable data access. Flexible licensing models. Better coverage and higher total value delivered. Those are just a few differentiators of our enterprise data solutions and packages tailored to your business priorities.

Contact UsThe WhoisXML API data engine is built and frequently upgraded to offer you the most complete, updated, and unique Internet intelligence footprints since 2010. Don’t get lost in all the red tape and unforeseen technical complexities of finding your own domain and DNS data. Our technology is ready to give back months or years of development cycle time to your most pressing and mission-critical projects and deployments.
Our Internet intelligence footprints support all types of security operations, such as:
Clients entrust their organization's cybersecurity to MDR teams primarily for the expertise they bring to the table. DNS, WHOIS, and other Internet records can further enhance MDR capabilities, highlighting the human skillset and etching reliability on the client's minds.
Every device connecting to the client's network is an endpoint, and each one has an IP address. Use WhoisXML API's IP intelligence to map out endpoints and discover otherwise hidden details about them, such as location, ISP, connection type, and Autonomous System (AS) information.
Providing accurate and contextualized security alerts lies at the core of XDR. Amplify the sophisticated mechanisms and algorithms that characterize XDR by integrating real-time and historical Internet events for threat detection, attribution, and contextualization.
In the early stages of penetration testing, digital asset enumeration and threat hunting are critical security operations processes. Use DNS, WHOIS, and other Internet data sources to boost penetration testing capabilities to identify digital assets relevant to a client's digital environment.
DFIR requires accurate and rich threat contextualization to fuel cybercrime and incident investigations. WHOIS, IP, and DNS intelligence contains critical data points that can take investigators one step closer to identifying the culprits.
WhoisXML API’s capabilities can help determine the health of an organization’s domain, website, IP and DNS records, and Secure Sockets Layer (SSL) infrastructure. Any misconfigurations or gaps in these areas can result in exploitable vulnerabilities.
An extensive and timely view of the DNS can help detection and response service providers deepen incident and vulnerability analysis, enrich threat intelligence, and enable real-time monitoring.

What Our Clients Say
"WhoisXML API has one of the largest WHOIS and DNS repositories I’ve used in my career as a data scientist. Their data has helped us really dive into the unique digital surfaces of our clients. As a result, we understand vulnerabilities and risk exposures better, in turn enabling our team to provide effective and specialized security services."
Data Scientist and Security Analyst
Managed Security Services Provider
"We found certain nameservers that were always used for a phishing campaign, having those in our rules enabled us to catch phishing sites before they affected our user base. WhoisXML API is a responsive and reliable provider of domain intelligence. Whenever there are issues, they are quick to respond and resolve them. Working with them is smooth and straightforward."
