These days, BYOD is the norm. Mobile devices from inside and outside your network are continuously crossing mixed physical and cloud infrastructure whose security may not always be under your control. As a result, your network is being constantly exposed to malware threats. And DNS is their main pathway. More than 90 percent of malware uses DNS to communicate with command and control servers, steal data, or redirect traffic to malicious sites. Existing security controls and perimeter defenses are not designed to prevent, isolate, and remediate DNS-based malware threats.
