Looking for a DNSViz alternative? Here's an honest, side-by-side comparison to help you choose the right domain security tool for your needs.
DNSViz is the definitive tool for DNSSEC chain of trust analysis and visualization, trusted by DNS experts worldwide. However, it only covers DNSSEC and produces complex output. Domain Security Scanner provides DNSSEC checking alongside five other security checks in a single, easy-to-understand scan result.
DNSViz is a free, open-source tool that provides detailed visualization of the DNSSEC chain of trust for any domain. Developed as an academic project, it offers the most thorough DNSSEC analysis available, showing the complete delegation and signing chain with interactive diagrams.

For general domain security scanning, yes. DNSViz provides the most detailed DNSSEC analysis available, while Domain Security Scanner covers DNSSEC plus SPF, DMARC, DKIM, SSL, and security headers. If you need deep DNSSEC debugging, use DNSViz. For a broad domain security audit, use Domain Security Scanner.
No. DNSViz focuses exclusively on DNSSEC chain of trust visualization and validation. It does not check email authentication records (SPF, DMARC, DKIM), SSL/TLS certificates, or HTTP security headers. Domain Security Scanner covers all of these.
For deep DNSSEC debugging and chain of trust visualization, DNSViz is unmatched. For a quick DNSSEC validation as part of a broader domain security audit, Domain Security Scanner is more practical. The two tools complement each other well.
