How it works

We show whether a domain is on public security lists. We don't analyse the page content.

1. Public lists

The domain is looked up in three independent lists of phishing, malware and scam domains. The lists are downloaded to your browser, so the list providers never see what you check.

2. DNS security filters

We ask four independent DNS services with malware and phishing protection (Cloudflare, DNS4EU, Control D, CleanBrowsing) whether they block the domain. Family filters are shown separately and don't affect the risk level.

3. Extra signals

Domain age (RDAP, where the registry publishes it)
Popularity (Tranco top 1 million)
Imitation of banks, couriers, state services and big brands
Short links are expanded first
For email: disposable address, mail servers, DMARC

Five-step result

CleanNot reported anywhere. That means not reported, not guaranteed safe.
Weak risk signalOne filter blocks it, it is very new, or the address has suspicious details.
Moderate riskAt least two security filters block it, or it imitates a known brand. Filters alone never go above this level.
High riskOn a scam / fake shop list, or brand imitation together with other signals.
Critical riskOn a phishing or malware list.
