About 80 percent of company web domains don’t have standard email authentication protections in place. DMARC is considered the industry standard for email authentication to prevent attacks where adversaries are sending mails with counterfeit addresses. Chinese companies are the least likely to adopt any DMARC policy, with 93.5 percent of domains having no policy in place, according to 250ok’s report. The report also found that law firms had the greatest increase in overall adoption from 2018 to 2019, with a 19 percent increase. European and U.S. retailers had the second and third greatest increases.
