Domain checker
Look up any domain against the live threat feeds and content-category lists ClearScreen endpoints enforce — URLhaus, OpenPhish, PhishTank, UT1, and StevenBlack. No signup, no email gate.
—
Absence of a listing is not a safety guarantee — it means the domain is not in the feeds and category lists checked here. Verdicts reflect ClearScreen's default policy; tenant policies choose their own category toggles.
What this checks
The lookup runs against the same data ClearScreen agents enforce on endpoints: phishing and malware indicators from URLhaus, OpenPhish, and PhishTank, plus web-content categories from the UT1 (Université Toulouse) lists and StevenBlack hosts. Security categories (malware, phishing, C2, stalkerware) are always blocked; content categories are policy toggles each tenant controls. Lookups are rate-limited per IP.
