Too Long; Didn't Read

In 2018, 93% of breaches began through a phishing or pretexting campaign (Verizon DBIR 2018) All it takes is one user falling for a campaign to potentially put your company at risk. SPF, DKIM, DMARC, and DKIM are key controls to combat phishing and spam. DKIM is a mechanism to digitally sign outgoing email from your domain, and establishes a protocol that verifies that the organization delivering the email has the right to deliver the message. SPF is simply a DNS TXT record that lists servers that are allowed to send mail for a specified domain.
