If you are using the Service on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms. If you do not agree to these Terms, you must not access or use the Service.

You must be at least 18 years of age to use the Service. By using the Service, you represent that you meet this age requirement.

2 Description of Service

Zondex operates a cybersecurity search engine that continuously scans and indexes internet-connected devices and services worldwide. The Service provides:

  • Statistical data and analytics about the global internet landscape
  • An API for programmatic access to search data
  • Exportable datasets for security research and analysis
  • Documentation, guides, and educational resources

The data provided by Zondex is collected from publicly accessible internet-facing systems using standard network scanning techniques. No authentication bypass, exploitation, or intrusive testing is performed during data collection.

  • Maintain and promptly update your account information
  • Keep your password secure and confidential
  • Accept responsibility for all activities that occur under your account
  • Notify us immediately of any unauthorized use of your account

We reserve the right to suspend or terminate accounts that violate these Terms, contain false information, or are used for malicious purposes. One person or entity may not maintain multiple free accounts.

4 Acceptable Use Policy

You agree to use the Service only for lawful purposes and in accordance with these Terms. Specifically, you shall NOT:

  • Use the Service in any manner that violates applicable local, national, or international law

We encourage responsible disclosure. If you discover a vulnerability through Zondex data, we urge you to report it to the affected organization following established responsible disclosure practices rather than exploiting it.

5 API Usage Terms

Access to the Zondex API is subject to the following conditions:

  • Rate Limits: API requests are subject to rate limits based on your subscription plan. Exceeding rate limits may result in temporary throttling or suspension of API access.
  • Authentication: API access requires a valid API key. You are responsible for keeping your API key confidential. Sharing API keys is prohibited.
  • Fair Use: API access is intended for integration with your own tools and workflows. Systematic bulk downloading of the entire database is not permitted.
  • Attribution: If you publicly display data obtained from Zondex, you must provide appropriate attribution to Zondex.io as the source.

Search query limits apply per account and are determined by your subscription tier. Specific limits are detailed on our Pricing page. We reserve the right to modify rate limits with reasonable notice.

6 Data & Search Results

The search results and data provided by Zondex are compiled from publicly accessible sources through automated internet scanning. While we strive for accuracy, you acknowledge that:

  • Data may not be real-time and could be outdated at the time of viewing
  • Search results are provided "as is" without warranties of completeness or accuracy
  • The presence of a device or service in our index does not imply authorization to access it
  • Vulnerability information (CVE data) is provided for informational and defensive purposes only
  • We do not guarantee the availability of any specific data or search results

If you are the owner or operator of a system indexed by Zondex and wish to request removal, please contact us at support@zondex.io.
