What is DMARC’s role in phishing prevention?

DMARC prevents domain-based **phishing** by blocking spoofed messages. When attackers try to send as your domain without authorization, **DMARC** enforcement (quarantine or reject) stops those messages from reaching recipients.

**DMARC** addresses specific **phishing** types: **domain spoofing** where attackers use your exact domain. It doesn't prevent: display name **spoofing** (fake name, different domain), lookalike domains (attacker-owned similar domains), or compromised legitimate accounts.

Despite limitations, **DMARC** significantly reduces **phishing** success. Enforced **DMARC** makes impersonating protected brands much harder, forcing attackers toward techniques that are easier for users to detect.
