Additionally, it’s important to keep software up-to-date and use security tools and plugins to help protect against these types of attacks.

What is DMARC email protection?

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing. It helps to prevent email-based attacks by ensuring that legitimate email messages are properly authenticated and delivered. In contrast, unauthorized or malicious messages are blocked or sent to the spam folder.

DMARC email protection allows domain owners to publish policies in their Domain Name System (DNS) records that define how email receivers should handle emails from their domain. These policies include instructions for messages that fail authentication checks, such as reject, quarantine, or allow.

When an email is sent, the recipient’s email server checks the DMARC policy of the sending domain to determine how to handle the message. If the email passes DMARC authentication, it is delivered as usual. If it fails, the recipient server will either reject the message or send it to the spam folder, depending on the policy specified by the domain owner.

DMARC email protection can prevent many email-based attacks, including phishing, spear phishing, and business email compromise (BEC) scams. These types of attacks typically involve a malicious actor sending an email that appears to come from a trusted source, such as a bank or a co-worker, to trick the recipient into disclosing sensitive information or taking an action that could harm their organization.

By implementing DMARC email protection, businesses can significantly reduce the risk of email-based attacks and protect their employees and customers from the potentially devastating consequences of these scams.
