What it is, and why we rate it

One line each. Open a row for detail.

What it really isSecurityTrails — DNS, IP, and domain intelligence platform for threat hunting and attack surface management.
Our takeSecurityTrails is a leading cyber-intelligence data platform giving security teams access to over 10 trillion historical DNS records, 4.2 billion WHOIS records, and 2.6 billion tracked hostnames.
The product is SecurityTrails (securitytrails.com). There is a persistent free tier, with paid plans scaling to enterprise contracts.
Why we rate itNo other commercial tool matches SecurityTrails' raw historical DNS depth.
For SOC teams and threat intelligence workflows, the API is a force multiplier — connecting infrastructure dots that other tools simply don't have.
The catchEnterprise-tier pricing ($11k–$70k/yr) puts serious scale behind a sales call.
The free tier is very limited at ~50 queries/month, making meaningful evaluation difficult without a paid commitment.

Best / not good for

Best for
  • Threat hunters correlating attacker infrastructure across historical DNS
  • Red teams and OSINT analysts mapping attack surfaces of target organizations
  • Security vendors enriching alerts with passive DNS and WHOIS context via API
Not good for
  • Small teams or individual researchers with tight budgets — enterprise pricing is steep
  • Real-time endpoint detection or host-based security (this is infrastructure intel only)
  • Non-technical users — value is almost entirely delivered via API and raw data
Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: API key available on free-tier signup; first DNS query in minutes. Meaningful threat-hunting workflows require paid volume.
  2. Scale breakpoint
    Query volume limits hit quickly on free/lower tiers; large-scale enrichment pipelines require enterprise contracts and budget approval cycles.
  3. Walled garden
    Moderate: data is queryable via API and exportable, but historical dataset depth is proprietary — no portable alternative exists at the same scale.
Still a fit?
If none of these block you, start on the free plan.
