DMARC: Email Security That Works Behind the Scenes

Prevent phishing, gain visibility, and take full control of your email reputation — without disrupting your day-to-day.

Is your domain safe from email spoofing?

DMARC (Domain-based Message Authentication, Reporting and Conformance) is a security protocol that prevents cybercriminals from sending fraudulent emails using your domain. It works by aligning two existing standards - SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) - to verify that emails claiming to come from your organisation are legitimate.

In simple terms: DMARC makes sure emails sent from your domain are genuinely from you - and blocks imposters who try to fake it.

Top Benefits of Implementing DMARC

  • Stops Email Impersonation: Blocks unauthorised senders from faking your email domain.

  • Protects Your Brand Reputation: Prevents phishing attacks that appear to come from your business.

  • Boosts Email Deliverability: Ensures your legitimate emails reach inboxes instead of spam folders.

  • Improves Visibility & Control: Gain clear insight into who is sending emails on your behalf — both authorised services and malicious actors.

  • Strengthens Regulatory Compliance: Supports compliance with cybersecurity best practices and regulatory standards.

How does DMARC work?

Step 1: Email is Sent

An email is sent from your domain — either by you or a malicious actor pretending to be you.

Step 2: Authentication Checks

The recipient’s mail server checks SPF and DKIM records to verify the sender.

Step 3: DMARC Policy Applied

If the message fails authentication, DMARC tells the server whether to deliver, quarantine, or reject it.

Step 4: Reporting & Visibility

You receive reports showing who is sending email from your domain — both legitimate and suspicious sources.
