# DMARC.com > DMARC.com helps domain owners secure email and reach an enforced DMARC policy (p=reject) without breaking legitimate mail. Its copilot, Thomas, names every sending source, generates the exact DNS records, and guides each domain from p=none to p=reject. ## Tools - [Free DMARC, SPF & DKIM analyzer](https://dmarc.com/en/analyze): instant public posture check for any domain. - [Domain check pages](https://dmarc.com/en/check/{domain}): per-domain verdict (is it protected against spoofing?), score and DMARC/SPF/DKIM status. - [DMARC Observatory](https://dmarc.com/en/observatory): sector barometers (e.g. banks by country) of public DMARC maturity, updated monthly. - [DMARC rankings](https://dmarc.com/en/catalog): browse the public DMARC posture of every domain we measure, searchable by sector and country. ## Learn - [DMARC](https://dmarc.com/en/dmarc): reference guide — the policy that ties SPF and DKIM to the visible From: domain and enforces a decision. - [SPF](https://dmarc.com/en/spf): reference guide — which servers are allowed to send for a domain. - [DKIM](https://dmarc.com/en/dkim): reference guide — the cryptographic signature that proves message origin. - [Blog](https://dmarc.com/en/blog): practical guides, including how to get to p=reject safely. ## Notes - Content is available in French (default), English (/en/...), German (/de/...), Spanish (/es/...). - Figures in the Observatory reflect public DNS at the stated date and can change as records are updated.
