DNSSEC Check: Professional DNS Security and Validation Tool Perform deep trust-chain validation, cryptographic audits, and standards-compliant reporting for any domain — all powered by the CyprNet Secure TrustPath Engine. This is the essential DNSSEC analysis tool for network and security professionals. — End-to-End DNSSEC Analysis —

Parent → child zone validation with authoritative-direct probing (DO=1, UDP 1232, TCP fallback)
Operates through corporate recursive resolvers when direct probing is restricted
DS ↔ DNSKEY mapping with match coverage
SHA-1 detection and crypto-grade scoring
RFC 8078 support: detect CDS/CDNSKEY for automated trust-anchor updates
Unified TrustReport model powering UI and HTML reports

— Free (Analysis) Experience —

Trust Chain Integrity: compact DS↔DNSKEY summary, parent zone info, match counts
Cryptographic Profile: SHA-1 cap indicator; DNSKEY algorithm list
Coverage of Signed RRsets: overall % from scoring
Pro features previewed with six distinct cards (headline metric visible; details blurred)

— Pro Capabilities (Full Toolset) — The Pro version unlocks the full suite of DNSSEC security features, including:

Delegation (CDS/CDNSKEY): presence detection, counts, TTL; guidance when missing (RFC 5011)
Parent ↔ Child Linkage: DS digest ↔ DNSKEY tag mapping, SHA-1 warnings, copyable records
Key Audit: algorithm distribution, KSK/ZSK counts, earliest/median RRSIG expiry
Coverage: SOA, NS, DNSKEY, apex A/AAAA, MX coverage of Signed RRsets
Mobile-First HTML Report: Professional, sortable, and shareable reports with findings and artifacts
Findings & Recommendations: Critical / Warning / Info; items link to report anchors

— Vantage Modes —

Authoritative-Direct: probes authoritative NS (RD=0, DO=1) with TCP fallback
Corporate-Recursive: labels resolvers; shows samples and capabilities; notes limitations
