Email—despite its importance, ubiquity, and staying power—has never been secure.
Prior attempts at security have failed to solve email’s fundamental flaw—anyone can send email using someone else’s identity. This flaw has put the power of the world’s most admired brands in the hands of cybercriminals. Through email, criminals can use almost any brand or email domain to send spam, phishing emails, and malware installs, inflicting direct losses to customers and eroding the brand equity companies have spent years building.
Many of the most respected brands in the world, including Facebook, Apple, JPMorgan Chase, and PayPal have adopted DMARC to protect their customers and their brand.
Using DMARC, companies gain unprecedented visibility into legitimate and fraudulent mail sent using their domain names. The magic of DMARC is the ability to understand all the different mail streams being sent claiming to be from you—third parties, business units, and threat actors. The overall impact to companies that have adopted DMARC is preservation of brand equity, elimination of customer support costs related to email fraud, and renewed trust and engagement in the company’s email channel.
DMARC—an open standard enabled on 70% of the world’s inboxes—is the only solution that enables Internet-scale email protection and prevents fraudulent use of legitimate brands for email cyberattacks.
