Domain Reputation API: Analyze the infrastructure of domains or IP addresses at scale via API calls

Audit domains or IP addresses in relation to their WHOIS records, Secure Sockets Layer (SSL) configuration, mail exchanger (MX) and name server (NS) configurations, and dozens of other parameters. Our bulk infrastructure checks allow making as many as 15 requests per second.

The API performs several domain infrastructure analyses, including:

WHOIS Domain Check

Domain Reputation API accesses an extensive repository of WHOIS records and lets you know if the domain’s registrant contact details are redacted or publicly available. It also analyzes its registrant country and checks if it is considered offshore.
MX Record Configuration Analysis

The tool analyzes main infrastructure servers, including MX records. It checks several parameters, such as Domain-Based Message Authentication, Reporting and Conformance (DMARC) and Sender Policy Framework (SPF) settings.
SSL Vulnerability Check

The tool analyzes the domain’s SSL configurations. It warns you if any parameter is not up to standards, including HTTP Strict Transport Security, TLS Authentication (TLSA), and Online Certificate Status Protocol (OCSP) stapling.
NS Record Configuration Tests

NS is another infrastructure server Domain Reputation API analyzes. The tool warns you if configurations do not meet best practices.
SSL Certificate Validity

Domain Reputation API checks the domain’s SSL certificate and informs you if it is invalid or has expired.
Malware Database Check

Domain Reputation API scans various malware engines to look for the Internet asset. If found, the tool lets you know so you can avoid accessing the malicious property.
