DNS Security Auditor
DNS and email security audit tool for DMARC, SPF, DKIM, and more
DNS Security Auditor is a free, open-source tool that analyzes a domain's email authentication and DNS security configuration. It checks standards like DMARC, SPF, DKIM, MX, MTA-STS, TLS-RPT, BIMI, DNSSEC, and CAA, then reports findings and suggested fixes. No account or data storage is required to use it.
Users enter a domain and the tool resolves its DNS records, validates them against known standards, and outputs a report of passing checks, warnings, and issues with remediation guidance.
