CSC Named Winner of the Top InfoSec Innovator Award for Most Innovative DNS Security

CSC, an enterprise-class domain registrar and world leader in mitigating brand, fraud, domain, and Domain Name System (DNS) threats, today announced that its Subdomain Monitoring solution took top honors for Most Innovative DNS Security in Cyber Defense Magazine’s 2026 Top InfoSec Innovator Awards.

CSC introduced Subdomain Monitoring after analyzing close to half a million DNS records and finding that many companies were exposed to subdomain takeovers due to dangling DNS. CSC’s solution helps enterprises reduce this risk and secure their online ecosystems. It was the first and only technology on the market to ease the burden of tracking and maintaining DNS records and purging unused zone records to prevent subdomain hijacking.

Subdomain Monitoring, powered by CSC’s one-of-a-kind DomainSec^SM threat intelligence platform, alerts DNS administrators and security engineers when it detects changes to their zone records. It also provides context on those changes, delivering greater visibility on threat vectors targeting global domain portfolios and enabling organizations to take informed action. With this capability, enterprises can clean up legacy records, easily integrate with the DomainSec platform, and conduct enforcement takedowns to prevent future subdomain hijacking.

“With the rise of AI, attackers exploit dangling DNS records at an unprecedented scale. For enterprises, this means the window between a subdomain becoming vulnerable and being hijacked is shrinking significantly,” says Mark Flegg, senior director of technology, Security Services, CSC. “We’re honored to receive recognition as one of Cyber Defense Magazine’s Top InfoSec Innovators. This award reflects our continued commitment to pioneering DNS security, providing our clients with the visibility they need to strengthen their DNS cyber hygiene and to keep AI-backed bad actors at bay.”
