We secure your domain from domain spoofing
Don't let attackers use your domain name to send email without your permission. DMARC+ helps prevent the illicit use of email domains to protect against online fraud, spam and phishing.
Can my domain be spoofed? Check its DMARC record free.
On 19 October 2026 we read the DNS of the top 1,000 domains. 180 of the 688 that receive mail still let anyone send as them: no DMARC record, or p=none. See the study.

Four steps to full DMARC enforcement
Go from zero DMARC coverage to full enforcement without disrupting your legitimate email flow.
Monitor
p=none
Start with a p=none policy to collect DMARC data. No emails are blocked. You gain full visibility into every sender using your domain.
Analyze
Identify senders
Review aggregate and forensic reports. Identify which senders are authorized and which are not. Map your entire email infrastructure.
Enforce
p=reject
Move to p=reject and block all unauthorized emails. Recipients never see spoofed messages from your domain again.
Comply
Stay compliant
Meet sender requirements from Google, Yahoo and Microsoft. Satisfy regulatory frameworks including GDPR, DORA, NIS 2 and PCI DSS.
DMARC compliance is now mandatory
Email authentication requirements are no longer optional. Major mailbox providers and regulators now enforce DMARC, DKIM and SPF. Non-compliance risks email delivery failures and regulatory penalties.
