Conversion Gems editorial verdict
Free tier (50 queries/mo); paid plans via sales
Features9/10
9 - unrivaled historical DNS/WHOIS dataset depth; strong API, DSL querying, subdomain mapping, and attack surface coverage.
Value5/10
5 - free tier is too limited for real use; enterprise contracts start at ~$11k/yr, making cost a barrier for most teams.
Ease of use7/10
7 - clean API and docs; web UI is accessible, but full power requires API fluency and security domain knowledge.
Ecosystem8/10
8 - widely integrated into SIEM, SOAR, and threat-intel platforms; extensive API with code samples for Python, JS, Go.
Support7/10
7 - API docs are solid; enterprise customers get dedicated support, but free tier support is minimal.
What it really is

SecurityTrails — DNS, IP, and domain intelligence platform for threat hunting and attack surface management.

Our take

SecurityTrails 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 DB name 'Security, Privacy & BackupTrails' is a catalogue mislabel — the category prefix was accidentally prepended to the product name; the real product is SecurityTrails (securitytrails.com). Pricing is also mislabeled: there is a persistent free tier (not merely a trial), with paid plans scaling to enterprise contracts.

Why we rate it

No 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 catch

Enterprise-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 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
Friction report
Time to value
Fast: API key available on free-tier signup; first DNS query in minutes. Meaningful threat-hunting workflows require paid volume.
Scale breakpoint
Query volume limits hit quickly on free/lower tiers; large-scale enrichment pipelines require enterprise contracts and budget approval cycles.
Walled garden
Moderate: data is queryable via API and exportable, but historical dataset depth is proprietary — no portable alternative exists at the same scale.
