The full domain report
Each tool on drwho.me checks one thing. Domain Posture runs all 18 checks on a domain at once, grades every result, and tells you what to fix first. The report is free.
- SPF, DKIM, DMARC, MTA-STS and TLS reporting, read together as one picture of who can send as you.
- DNS
- Records, mail servers and DNSSEC.
- Web
- TLS certificate, security headers, redirects, CORS and what the site exposes.
- Discovery
- WHOIS and the subdomains that certificate logs reveal.
- AI readiness
- What robots.txt tells AI crawlers, llms.txt and security.txt.
What you get there that you do not get here
A grade for every check, a list of fixes in order of importance, and one page you can share. Paid plans add scheduled re-checks, alerts when something changes, and signed evidence packs for security questionnaires.
What stays here
Every single check on drwho.me stays free, with no account. Use them as often as you like.
