Frequently asked questions
Everything about the checks, the plans, and billing.
What does DomSec HQ actually check?
11 checks across your domain's email authentication and web security posture: MX, SPF, DKIM, DMARC, BIMI, blacklist status, MTA-STS, TLSRPT, DNSSEC, SSL/TLS certificate health, and security headers. Anyone can run the first 5 for free with no signup; a free account unlocks all 11 plus a downloadable PDF report.
What's the difference between Free, Basic, and Pro?
Free monitors 1 domain, checked roughly once a month. Basic monitors up to 10 domains on a weekly cadence, with degradation alert emails, custom DKIM selector monitoring, and instant on-demand rechecks. Pro includes everything in Basic, plus dark web and breach monitoring for your domain's mailboxes (coming soon). See the pricing page for the full comparison.
Can I cancel anytime?
Yes. Subscriptions are billed monthly or annually with no minimum term. Cancel anytime from the billing portal on your dashboard — you'll keep paid features until the end of the period you've already paid for, then drop to the free plan automatically.
Do you store my domain or account data securely?
Passwords are hashed, never stored in plain text. Payments are handled entirely by Stripe — we never see or store your card details. Domain check results are only visible to the account that added the domain.
Will checking a domain I don't own cause any problems?
No. Every check is a standard, read-only DNS/HTTP lookup — the same kind of request your own browser or mail server makes. Nothing is sent to the domain that could be considered intrusive, and running a check doesn't notify or affect the domain owner in any way.
How often are my monitored domains checked?
Free accounts: roughly once a month. Basic and Pro accounts: weekly, plus an instant recheck button on paid plans if you want results right now (limited to once a minute per domain to avoid hammering DNS).
What happens if a check fails or a score drops?
Paid accounts get an email alert when a monitored domain's score degrades between checks, so you find out from us before you find out from a bounced email or a spoofed message.
What payment methods do you accept?
All major debit and credit cards, processed securely by Stripe.
