on a comprehensive set of data sources

Analysis Reputation score Domain / IP

Evaluate the reputation of a domain or IP by using a host of security data sources together with an instant audit of external configuration. For the domain name or IP address you are interested in, gather and assess over hundreds of parameters to calculate its reputation score. You can investigate multiple properties of the domain or IP ever since it was registered and gauge likely threats and plausible risks from domains or IP that do not appear to have been involved in wrongdoing.

The resulting reputation score is based on

  • The website content and it relation to other domains, and host configuration
  • The domain's SSL certificates, SSL connection, and configuration
  • DNS MX records configuration and corresponding mail servers
  • The domain's WHOIS record
  • Whether the domain is deemed dangerous in numerous malware data feeds all over the Internet
  • Configuration of the name server
  • Infrastructure of the domain's IP addresses
  • Reverse IP lookup


An accurate estimation considering hundreds of parameters

The resulting risk score will range between 0 (low risk) and 100 (high risk). The higher risk scores are given to already known malicious Registrant, IP addresses, and Name Servers. This approach helps users to identify malicious domains before getting involved with them.

Forewarned is forearmed

Domains are estimated right upon their registration. Block out untrustworthy domains before they can harm you. Figure out what type of risk a dubious domain may represent.
