SecurityTrails API is the search engine for internet infrastructure. It excels by turning the invisible connections of the internet into searchable data, making it an essential tool for threat hunters and bug bounty hunters alike. For a Security Engineer or SOC Analyst, its value lies in Asset Discovery and Historical Context—it allows you to see not just what a domain looks like today, but everywhere it has been in the past. It is the premier choice for organizations that need to map their digital footprint or investigate cyber adversaries with precision.
Pros & Cons
- Because it’s a standard REST API, it can be added to existing security workflows (SOAR) in minutes.
- The documentation is exceptional, with copy-paste code snippets in multiple programming languages.
- Exceptional at finding overlooked or lesser-known subdomains that security teams might have missed.
- The API focuses on infrastructure (DNS/IP) rather than the content on the pages
- Strict enforcement of rate limits on lower-tier plans can disrupt automated scripts if not managed carefully.
Features
Key features
Frequent scanning ensures that new subdomains and DNS changes are reflected in the API with minimal latency.
Programmatic access to current and historical WHOIS ownership records, even for domains that have since become private.
Identifies other domains hosted on the same IP or IP range, helping to find malicious neighbors or shared infrastructure.
Provides a "time machine" for DNS, allowing users to see past A, AAAA, MX, NS, SOA, and TXT records.
Instantly finds all subdomains associated with a root domain (e.g., finding dev.example.com from example.com), critical for finding "shadow IT."
Additional features
Categorize domains based on their infrastructure (e.g., "Amazon Web Services").
Access to SSL logs to find newly issued certificates for a domain.
A high-volume stream for enterprise users who need to ingest all new internet changes.
Search for all domains owned by a specific legal entity/company.
Look up the domain name associated with a specific IP address.
Discover domains that share the same tracking codes (like Google Analytics IDs).
Real-time dashboard to monitor your query consumption and limits.
Ability to download large datasets for offline big-data analysis.
Filter results by record type, date ranges, or specific string matches.
Query by domain name to get immediate technical overviews.
