Domain Reputation Checker

Check domain reputation scores and identify potentially risky domains

Domain Reputation Checker

You can enter up to 10 domains. Domain reputation checks include abuse status, registration details, and risk scoring across multiple dimensions.

What is Domain Reputation?

Domain reputation is a score that indicates how trustworthy a domain is based on various factors including its history, email sending behavior, and association with malicious activities. A good domain reputation is crucial for email deliverability and online trust.

How Domain Reputation Scoring Works

Overall Score

  • Good (0 or higher): Domain has positive reputation
  • Suspicious (-1 to -5): Domain shows some risk indicators
  • Bad (below -5): Domain has significant reputation issues

Dimension Scores

  • Human: Scoring based on manual investigations by research teams. Used when automation isn't possible, such as understanding adversaries' tactics, tools, and procedures (TTPs).
  • Identity: Automated scoring based on domain identity factors including email authentication and encryption configurations.
  • Infrastructure: Automated scoring based on infrastructure factors including name servers and domain hosting. Poor IP reputation (DROP datasets) can adversely affect this score.
  • Malware: Automated scoring based on malware associations from various intelligence feeds. Includes domains distributing malware or associated with botnet infrastructure.
  • SMTP: Automated scoring based on global email metadata patterns from email service providers and security partners.

Why Check Domain Reputation?

  • Verify domains before using them for email campaigns
  • Identify potentially malicious or compromised domains
  • Check domain age and registration details
  • Assess email deliverability potential
  • Protect your brand from association with bad domains

Tips for Maintaining Good Domain Reputation

  • Maintain consistent WHOIS information
  • Implement proper email authentication (SPF, DKIM, DMARC)
  • Follow email best practices and avoid spam-like behavior
  • Monitor your domain for abuse and unauthorized usage
