FAQ

Questions SecurityTrails owners ask.

  • 01

    Is the SecurityTrails API free to use?

    SecurityTrails offers a Free Tier API plan which allows 50 API requests per month. This is excellent for specific, targeted OSINT investigations. For automated or large-scale recon, you would need a commercial subscription.

  • 02

    What is historical DNS good for?

    Companies often migrate infrastructure and hide behind WAFs like Cloudflare. Historical DNS reveals the original origin IP addresses used before the WAF was implemented, which might still be active and vulnerable to direct attacks. It's a critical capability in penetration testing.

  • 03

    How can I find related domains for a target company?

    Use the get_associated_domains capability. It uses proprietary correlation to find other domains owned by the same entity. You can also use get_domains_by_ip to find what else is hosted on their IP space.
