A domain reputation check assesses whether a domain is safe, suspicious, or malicious by examining its threat history, registration, DNS, SSL, and hosting signals. WhoisFreaks runs six checks in real time and returns a verdict, a 0 to 100 trust score, and the reasons behind the result across 1,528 TLDs.
Feature: Real-time checks across six data sources, from threat feeds to live DNS, WHOIS, and SSL
Feature: A 0 to 100 trust score with the positive and negative signals behind it
Feature: Built-in DGA detection that flags algorithmically generated domain names
Feature: Free single-domain checks with no signup required
For automated, high-volume domain checks at scale, WhoisFreaks offers a Domain Reputation API for programmatic risk scoring with the same verdict, trust score, and evidence available through this tool.
Domain reputation improves when the signals behind the score improve. Publish SPF and DMARC records, install a valid SSL certificate, clean up the landing page, and keep registration details consistent while the domain ages. Recheck after each fix to confirm the trust score moved.
Implement SPF, DKIM, and DMARC records to verify your domain identity and prevent spoofing by unauthorized sources.

A domain reputation check shows whether a domain can be trusted before you click, deliver, or connect to it. Below are four common use cases, from security triage to fraud prevention.
Analysts check suspicious domains from alerts and logs to decide whether to block, monitor, or clear them, using the evidence trail to see why a domain was flagged.
Email and abuse teams check sender and link domains to spot phishing infrastructure, often before a domain has any reported URL on it.
Trust and safety teams check domains submitted by users at sign-up or listing time to keep fake and throwaway domains out of their platform.
Researchers, registrars, and buyers check a domain's history and risk signals before acquiring, listing, or trusting it.
WhoisFreaks scores a domain from six checks that run in real time: a match against curated threat intelligence, live DNS, WHOIS, and SSL lookups, a landing-page content check, and a DGA analysis of the domain name. The results combine into one verdict and one trust score, usually in four to five seconds, with every signal listed so you can see the reasoning.
The check combines six signals:
