What is DMARC
DMARC is a must-have for companies that want to secure their email traffic. It helps reduce spam and phishing.
DMARC stands for Domain-based Message Authentication, Reporting & Conformance. It is a protocol that helps companies improve the security of email messages and limit spam and phishing messages. Besides DMARC, it's also worth looking into what SPF or DKIM can do for you.
What is the purpose of DMARC?
DMARC provides an extra layer of security to ensure that email messages sent to a domain really do come from the stated sender. For example, if a company sends an email to a customer, DMARC will verify whether the email actually originates from the company's domain.
How does DMARC work?
To use DMARC, a company must add a DMARC record to the domain's DNS zone. The record contains information about what the recipient should do if the email doesn't comply with the security rules. For example, the recipient can mark the email as spam or the email can be deleted.
In addition, DMARC also provides a reporting system that gives companies information about domain name usage. This information can help identify unauthorized users attempting to impersonate the company.
DMARC is a powerful protocol that helps companies better secure their email traffic, reduce spam, and prevent phishing messages. It's an excellent tool for strengthening a company's reputation and increasing customer trust.
