About Suspicious Domain Checker

The Suspicious Domain Checker is a free tool that checks any domain name for suspicious activity. It does not require any personal information, nor does it collect any data about you.

The tool scans the WHOIS records of domains and IP addresses (if available), checks if there are open ports on those IPs, and looks for domain registration details from or other similar services. It also checks whether the domain has been blacklisted by Google Chrome or Tor Browser (at least 2 out of 3 tests must pass).

In addition to checking domains and IP addresses, this tool also checks email accounts associated with those domains for spamming behavior such as phishing emails or unsolicited marketing messages sent without permission from the recipient(s).

The Suspicious Domain Checker tool checks domain names against a number of sources to determine if they are suspicious. It includes WHOIS lookup, DNS lookup and analysis from SULTREND.

The tool is available through the Dashboard section of our website. You can access it by clicking on "Tools" in the top menu bar and then selecting "Suspicious Domain Checker". There is also a link in the footer of all pages so that visitors don't need to search for it specifically.


 The Suspicious Domain Checker uses data from several sources, including Cloudflare's ThreatLabs and VirusTotal (both free services). These sources provide information about domains found on their networks such as IP addresses used by endpoints hosting websites or data indicating malicious activity such as phishing emails or malware downloads from those sites' visitors. If there are any red flags associated with these domains (such as being hosted at an off-shore location or having seen spikes in traffic but not receiving payment), they will appear when searching them using this tool along with other potentially suspicious factors like being registered under an offshore registrar or having been blacklisted by Google Security alerts ).
