SecLookup is a real-time threat intelligence platform that provides domain enrichment, malicious URL detection, DNS/WHOIS/SSL lookups, and comprehensive security API for cybersecurity professionals and security operations teams.

How does SecLookup detect malicious domains?

SecLookup uses multiple threat intelligence sources including VirusTotal integration, proprietary machine learning models, and real-time threat feeds to detect malicious domains, phishing sites, malware distribution networks, and other security threats.

What data does SecLookup provide for domain enrichment?

SecLookup provides comprehensive domain enrichment including DNS records (A, AAAA, MX, TXT, NS, CNAME), WHOIS registration data, SSL/TLS certificate information, IP geolocation, threat reputation scores, and historical data.

Does SecLookup offer an API?

Yes, SecLookup offers a RESTful API that allows developers to integrate threat intelligence into their applications, SIEM systems, and security workflows. The API supports JSON responses and includes endpoints for domain scanning, bulk lookups, and threat data retrieval.

Can I report a false positive to SecLookup?

Yes, if your domain has been incorrectly flagged as malicious, you can submit a false positive report through the SecLookup website at seclookup.com/false-positive-submission. The security team typically reviews submissions within 24-48 business hours.
