Protect Your Business with DMARC Email Security

Email is at the heart of your business — and the #1 target for cybercriminals. DMARC helps stop spoofing and phishing so customers, partners, and employees can trust every message from your domain.

HOW DMARC WORKS

What is DMARC?

DMARC (Domain-based Message Authentication, Reporting & Conformance) works alongside SPF and DKIM to authenticate senders, block malicious mail, and provide actionable reports on suspicious activity. Publishing a DMARC record in your DNS tells receiving servers how to handle messages that fail authentication.

Authenticate

Aligns SPF & DKIM to prove mail is legit.

Report

Aggregated feedback reveals abuse patterns.

Block

Stops spoofing & phishing at the gateway.

Improve

Optimize deliverability with data.

Why DMARC Matters for Your Business

Without DMARC in place, attackers can impersonate your brand, trick your customers, and compromise sensitive data. Proper implementation helps safeguard your reputation and your inbox
