Discover and investigate domains with open source intelligence.
Domain Search provides security teams, analysts, and investigators with visibility into the DNS, SSL, and IP infrastructure behind more than 300 million domains and billions of hostnames. It works as a standalone OSINT tool and can also integrate with the DigitalStakeout XTI OSINT Platform, where it becomes part of a broader open source intelligence workflow for threat detection and infrastructure analysis.
Why Domain OSINT Matters
Domains and the infrastructure that supports them are often used in phishing, fraud, and cyber attacks. Identifying suspicious registrations, tracking infrastructure changes, and correlating domains to IP addresses or SSL certificates can reveal threat actor activity before it escalates. Domain Search delivers the open source intelligence needed to map adversary infrastructure and protect organizational assets.

Law Enforcement
Open source intelligence for cybercrime investigations
Investigators use Domain Search to link malicious infrastructure to threat actors, uncover hosting details, and preserve records for evidence.
Public Agencies
Situational awareness for government networks
Agencies search suspicious domains to detect phishing campaigns, correlate infrastructure, and support public sector cyber defense efforts.
Corporate Security
Brand and executive protection with domain OSINT
Security teams search for typo domains and unauthorized registrations targeting brands or executives, then connect results to takedown or legal workflows.
Cybersecurity Teams
Attack surface management and threat intelligence
Analysts use Domain Search to identify exposed subdomains, detect cloud asset risks, and monitor DNS changes that indicate compromise.
Security Firms
Client reporting and due diligence
Firms leverage Domain Search to map infrastructure tied to clients, assess external risk exposure, and deliver professional OSINT reports.
