CyberTOOLBELT (CTB) is a comprehensive set of tools designed to make investigations regarding domains, IP addresses and other related information as cost effective, user-friendly and efficient as possible. CyberTOOLBELT has many features that are not available anywhere else at any price. Example: Can your existing tool search all domain names where the domain name contains pixel and any of the contacts are located in New York and was registered in the last week? CyberTOOLBELT can! Typically in less than a second.

CyberTOOLBELT is exceedingly cost effective and eliminates hours of searching the web using stand-alone tools. The results are comprehensive. CTB is more than a set of tools, it is an investigative platform supporting dossiers and data sharing.

Current database statistics:

Count Data Category
324,675,028 Domains
3,247,361,781 Items related to Domains
357,819,605 Subdomains (not counting www)
88,378,182 Name Servers
78,606,430 IP addresses
197,974,972 Domains with Whois Information
36,892 Registrars and Resellers
69,592,098 Email Addresses
74,273,300 Whois Record Updates

Note that counts for all items (ie, domains, ip addresses, etc) are for unique items

CyberTOOLBELT is available with a ten-day free trial Bronze plan. If you like it and/or find that it saves you money and time you can easily convert to a paid subscription — which at a entry level of $11.95 per month is the best ROI on the planet. Just think, if it saves you 20 minutes a month (or 1 minute a day) it more than pays for itself!

You can also access CyberTOOLBELT data using a RESTful API at significantly higher data usage limits at a very reasonable cost (including on-premises Whois data for unlimited access). Contact sales for details.

Version 1.3 Released!

We released version 1.3 on July 6, 2015 with 2 new tools. The tools return either all the domains related to an MX server or all the domains that we know are hosted on a particular name server. We've added over a dozen informative/instructional videos and are adding 2-3 a week. Many changes were made to make the RESTful API easier to use and more powerful. In addition, we are now exposing IP Whois data through the API. Issue #15 of our newsletter has complete details.

Security must include domain name protection

Experts say that detecting fake websites needs to be a part of all companies' security protection. CyberTOOLBELT provides a great tool that allows you to monitor across all TLDs (new and old) for new domains related to your company. Read the full article by Warwick Ashford of here.

Customer Testimonials

CTB is a cost effective tool and reduces time spent searching the web for standalone sites that compile the information separately. It is a one-stop platform for handling certain areas of investigation. One great tool is the "Tell Me When" tool is used to monitor parked content pages and alerts when the domain has real content on the site. You can elect to take a snapshot of the page when the content is detected. This is also an option for monitoring domain keywords. CTB can automatically perform this operation when a domain has matched one of your keywords and starts hosting content. This is powerful for brand protection. Tracking web pages is easy with the "Track Web Pages Tool" which is used to monitor Web site changes, log the changes and then sends a notification email. Another interesting tool is the "Verify Email Address" tool which verifies an email address to determine if the user exists at that email provider. CTB has removed the tedious searching and created an environment where I am confident in the results. With these tools there is less "shifting sand" and more "Yes, I can do this for you!"
