Three years after Russian hackers targeted and breached the email accounts of Hillary Clinton’s presidential campaign, nearly all of the upcoming 2020 presidential candidates are still lagging in email security.
New data out by Agari confirms just one presidential hopeful — Democratic candidate Elizabeth Warren — uses domain-based message authentication, reporting, and conformance policy — or DMARC. This email security feature sits on top of two existing security protocols, Sender Policy Framework (SKF) and DomainKeys Identified Mail (DKIM), which cryptographically verifies a sender’s email, and can mark emails as spam or reject them altogether if an email can’t be properly validates.
Agari, which has a commercial stake in the email security space, said the remaining 11 candidates it checked — including Bernie Sanders, Joe Biden, and presidential incumbent Donald Trump — do not use DMARC on their campaign domains.
