DMARC monitoring that tells you what to fix. Monitor SPF, DKIM, DMARC and 6 more email authentication protocols from one dashboard, get step-by-step fixes, and move from p=none to p=reject with audit-ready compliance evidence.
DMARCguard started from frustration: every DMARC tool showed data and left you to figure out the rest. So we read every RFC, mapped every protocol, and built the tool we wished existed, one that tells you exactly what's wrong and how to fix it.
We implement the RFC, not an approximation. We name the failing source, explain why it matters, and tell you what to change. We're bootstrapped and EU-based, with a free plan that stays free, transparent pricing, and a promise never to sell your data.
