FAQ
Frequently Asked Questions
What types of threats does the database include?
The database covers malicious IPs, domains, and URLs across every major threat category: phishing sites, malware hosts, botnet command-and-control infrastructure, ransomware indicators, adware networks, tracking domains, and vulnerability intelligence with CVE mappings.
How often is the database updated?
The database is refreshed daily, with continuous ingestion from our source network around the clock. Newly registered domains, fresh phishing sites, and emerging threat infrastructure are added as sources report them, so blocklists and API responses always reflect current threat data.
Is there a free tier?
Yes. The free plan includes 30 checks per month and a free API key — no credit card required. It is a full-featured way to evaluate the database before upgrading to a paid plan for higher volume.
Can I export blocklists?
Yes. Blocklist exports are available on paid plans in formats ready for firewalls, DNS resolvers, and SIEM ingestion. PDF report exports are available for free.
Where does the data come from?
Threat data is aggregated from 500+ verified commercial, open-source, and community intelligence sources. Each source is reliability-weighted, and indicators confirmed by multiple independent sources receive higher confidence scores to reduce false positives.
