Most domains are exposed. Is yours?

Google, Microsoft, and Yahoo now reject unauthenticated email from bulk senders. PCI DSS 4.0 made DMARC mandatory in March 2025. NIS2 carries penalties up to €10M. Your domain is either compliant, or it's a liability.

We built DMARCguard because every email security tool we tried made the same mistake: they showed us data and expected us to figure out the rest. We read every RFC. We mapped every protocol. Then we built the tool we wished existed — one that tells you exactly what's wrong and exactly how to fix it.

The core parser is open-source because security tools should be auditable. The platform is modern because complexity shouldn't mean ugly.

Frequently asked questions

What does DMARCguard actually do?

DMARCguard monitors your email authentication protocols — DMARC, SPF, DKIM, BIMI, MTA-STS, TLS-RPT, ARC, and DANE — from a single dashboard. It collects your DMARC aggregate reports, identifies who’s sending email on your behalf, and gives you step-by-step guidance to reach full enforcement (p=reject).

What if I need help getting to p=reject?

That’s exactly what we’re built for. DMARCguard identifies every authorized sender, flags misconfigurations, and gives you a step-by-step path from p=none through p=quarantine to p=reject. Paid plans include priority support for enforcement guidance.

Do I need to be technical to use it?

No. DMARCguard translates raw XML reports into plain-language insights. You’ll see sender names like “Mailchimp” and “Google Workspace” instead of IP addresses, and every issue comes with a clear recommended action.

Does DMARCguard help with PCI DSS 4.0 and NIS2 compliance?

Yes. PCI DSS 4.0 Requirement 5.4.1 mandates DMARC. DMARCguard provides compliance scoring, audit trails, and exportable PDF reports that serve as evidence for auditors. Our architecture also aligns with NIS2 and GDPR requirements.

How is DMARCguard different from EasyDMARC, dmarcian, or PowerDMARC?

Three key differences: (1) all 8 protocols are included at every tier — competitors gate protocols behind premium plans, (2) we provide actionable remediation guidance, not just monitoring dashboards, and (3) our pricing is 50–80% lower for comparable coverage. See the full comparison above.

What’s the difference between the free plan and paid plans?

The free Starter plan covers 2 domains with all 8 protocols, 30-day data retention, and email alerts. Paid plans add more domains, team members, longer retention, compliance scoring, API access, PDF reports, and priority support. Every plan includes full protocol coverage — we never gate security features.

How long does setup take?

Under 2 minutes. Add your domain, publish one DNS TXT record, and reports start flowing in. DMARCguard scans your existing DNS configuration immediately and shows your security grade before the first report arrives.

Can my team collaborate on this?

Yes. Pro supports 5 team members, Business supports 15, and Enterprise is unlimited. Role-based access lets you give auditors read-only views while admins manage policy changes. Every action is logged in the audit trail.

What happens to my data?

Your data is stored securely with encryption at rest and in transit. Retention depends on your plan (30 days to unlimited). We’re SOC 2-ready, GDPR-compliant by design, and you can export or delete your data at any time.

Is there a contract or cancellation fee?

No. All plans are month-to-month (or annual with 20% savings). Cancel anytime — no penalties, no lock-in. Your data remains exportable for 30 days after cancellation.
