What is DMARC?
Phishing emails are one of the primary attack-vectors in 2024 and while user training and MFA is important, we must not forget to set up the basics. Which not only includes SPF and DKIM, but also DMARC.
DMARC (Domain-based Message Authentication, Reporting and Conformance) extends upon both SPF and DKIM (which I covered in my previous Youtube video) to authenticate incoming email. It is a TXT record in the DNS for your email-domain and the DMARC checks are based on the settings in this record. For a more detailed explanation of DMARC, check out my YouTube video where I dive deeper into the topic.

Remember, DMARC is a powerful tool in the fight against email spoofing and phishing. Stay safe online!
