What is DMARC?

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol designed to protect your organization’s domain from spoofing and phishing attacks. It works alongside SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to ensure that only authorized senders can use your domain to send emails.

Pain Points Addressed

• Email Spoofing: Prevents cybercriminals from sending fake emails using your domain.

• Phishing Brand Abuse: Blocks fraudulent emails pretending to be from your company.

• Lack of Visibility: Provides detailed reports on who is sending emails using your domain.

• Customer Trust Risks: Reduces the chance of customers receiving fake emails from your brand.

Use Cases

• Protecting executives and employees from CEO fraud and business email compromise (BEC).

• Preventing attackers from using your company domain in phishing campaigns.

• Monitoring unauthorized third-party services sending emails on behalf of your domain.

• Enforcing strict email authentication to improve the deliverability of legitimate emails.

Compliance Benefits

DMARC helps organizations comply with GDPR, HIPAA, PCI-DSS, NIST, and ISO 27001 by:

• Ensuring secure email communication.

• Reducing the risk of data leaks via spoofed emails.

• Providing audit-ready reports of email authentication.

Business Email Flow Protection
