Grade any domain in 10 seconds.
Enter a domain. We'll check DMARC, SPF, SSL, MTA-STS, DNSSEC, CAA, and registration hygiene, then hand back an A+ to F security grade with the fixes that would move it up.
What you get
- A grade, not a wall of acronyms
One A+ to F letter grade, one verdict, ranked next steps.
- The full PDF if you want it
Email it to yourself. Watermarked sample, no card.
- Optional ongoing monitoring
Sign up free to re-grade the domain daily and, during the 30-day trial, get an email if its DMARC policy changes.
Why this matters
Without DMARC enforcement, a working SPF, a valid SSL certificate and a few DNS hardening records, your domain can be impersonated today. Most owners only find out after a customer complains. This scan checks the same outside-in surface attackers probe for weaknesses and many cyber-insurance forms ask about, and tells you whether the controls are present, where the gaps are, and what the highest-impact fix is.
Frequently asked
Do I need to sign up?
No. You see the grade and your top issues without an account. The step-by-step fixes and ongoing monitoring are gated behind a free signup.
Can I scan a domain I don't own?
Yes. Every check we run uses public DNS responses. To receive the PDF report by email for a domain that doesn't match your email, you'll get a confirmation link first.
What's the difference between this and the security grade checker?
Same scanner, different audience. The grade checker leans into the A+ to F report card. The scan funnel leans into the fix-it plan and an emailable PDF.
