How Secure Is Electronic Voting in Today's Digital Landscapes? | UpGuard

This report evaluates the web- and perimeter-security posture of major voting-system vendors (ES&S, Unisyn, Smartmatic, Dominion, OSET, Clear Ballot), documenting widespread misconfigurations—missing sitewide SSL, exposed ports, disabled HSTS, absent SPF/DMARC/DNSSEC, and insecure cookies—and links those weaknesses to real-world risks by referencing past breaches of political and voter-registration systems, concluding that such flaws could threaten election integrity and recommending digital resilience measures.
