Comprehensive DNS, email security, TLS, and domain reputation analysis. Enter any domain to get a full health report.
You can paste a full URL — the protocol, path, and port will be stripped automatically. Supports any public domain.
A comprehensive server-side analysis of any public domain — DNS records, email authentication, TLS certificates, registration data, and IP blacklist status.
A, AAAA, MX, NS, TXT, SOA, CNAME, CAA records with hosting provider identification.
SPF, DMARC, BIMI, and MTA-STS validation. Detects policy gaps enabling spoofing.
TLS version, cipher, certificate validity, expiry, SANs, and CT log analysis.
Checks resolved IPs against DNS-based blacklists (RBLs) for listing detection.
The health score (0–100) is a weighted composite across four categories. Each check contributes pass, warn, or fail findings that produce the final grade.
Type or paste any domain name or URL. The tool automatically strips the protocol, path, and port to extract the domain.
Our backend resolves DNS records, connects to the domain for TLS inspection, queries blacklists, and validates email security policies.
Receive a health score (A+ to F) with detailed findings across DNS, email security, TLS, and domain reputation categories.
