DNS Security delivers enterprise-grade DNS control and filtering with rapid resolution for unbeatable performance and availability with the industry’s most comprehensive cloud native security service edge (SSE) platform.
Sophisticated DNS-based attacks bypass legacy security tools
The Domain Name System (DNS) is integral to how we use the internet, but as a decades-old service, it’s being tested in the modern digital world. Surging traffic from hybrid and remote work, cloud applications, and IoT/OT devices greatly impacts DNS performance and availability—and DNS is a popular vector for threat actors to exploit. Commonly found in firewall allowlists, DNS and now DNS over HTTP/S (DoH) can easily mask DNS attacks. Without monitoring and protection at scale, adversaries can deliver threats and exfiltrate data undetected.
