The Global Cyber Alliance (GCA) on Monday released an interactive tool that consumers, businesses, and governments can use to “measure and quantify” the deployment of the Domain-based Message Authentication, Reporting & Conformance (DMARC) email security protocol. DMARC is an anti-phishing and anti-spoofing tool that helps users ensure emails they receive come from legitimate email domains. Called the GCA DMARC Leaderboard, the tool currently provides intelligence on more than 500,000 email domains, according to GCA. As part of the dashboard, users are able to rank DMARC usage by country, industry, and DMARC policy level. GCA expects rapid growth from the tool and says it will “provide DMARC intelligence on more than 10 million email domains by the first quarter of 2019.” Philip Reitinger, president and CEO of GCA, explained, “The GCA DMARC Leaderboard offers a way to compare countries, sectors, and companies as to their progress in deploying email spoofing protections, and we hope it helps lead to universal adoption of DMARC. Using DMARC to prevent email domain spoofing is essential as an anti-phishing measure.”
