See pricing.What you get back
SSL certificate
We open a live TLS connection and read the certificate. You get the issuer, issue date, expiry, days remaining, and every hostname the cert covers.
Domain registration
Queried over RDAP (the modern WHOIS replacement) for the registrar, registration date, expiration, and registry status codes.
DNS records
Live lookups against 1.1.1.1 for A, AAAA, MX, NS, TXT, CAA, and SOA. No cached data, no stale answers.
Email authentication
SPF, DKIM, and DMARC audit with an A to F deliverability grade. We flag what's missing, misconfigured, or too permissive.
Blacklist reputation
Your IP checked against Spamhaus ZEN, Barracuda, SpamCop, and SORBS so you catch mail reputation problems before customers do.
Export your report
Every lookup can be saved as a branded PDF or CSV, so you can archive it, share it, or hand it to a client.
