What threats does DMARC protect against?

DMARC (Domain-based Message Authentication, Reporting & Conformance) allows a sender’s email infrastructure to indicate that its messages are protected by SPF (Sender Protection Framework) and/or DKIM (Domain Keys Identified Mail), and tells a receiver what to do if neither of those authentication methods passes – such as junk or reject the message.

Without DMARC, spoofers can steal personally identifiable information (PII) by sending emails that appear to originate from your domain.

They do this by falsifying the header “from” address – that’s the one visible in the From: field.

Get Visibility

Gain visibility of the sources and email flows for messages sent from your domain. Recognize valid senders – like email marketing, CRM, support and other services you use – and uncover any unauthorized use of your brand.

Take Charge

Identify legitimate sources authorized to send emails on your behalf and authenticate them. Monitor and make adjustments in observation mode, then simply enforce the policy, to tell ISPs to reject or junk failing messages.

Increase Security

Prevent cybercriminals sending fraudulent emails to your business partners, employees and customers by spoofing or impersonating your sending domains.
Prevent disclosure of your sending sources with LetsDMARC hosted SPF with macros and reduce your attack surface.

With a DMARC policy implemented and unauthorized sources blocked from sending on behalf of your domain, your reputation as an email sender will be enhanced, helping to improve your email deliverability.
