CISO Guide to DNS Security: Stop Your Top Network Risk

DNS resolution is the foundational first step of nearly every digital interaction. Yet, while 95% of organizations experienced a DNS-related incident over the past 12 months, only 33% actively inspect DNS traffic for threats. Legacy security stacks—including Next-Gen Firewalls, IPS, and EDR—are not built to analyze continuous streams of DNS queries, leaving critical gaps like DNS tunneling, Data Generation Algorithms (DGAs), and NXDOMAIN anomalies undetected.

The CISO Guide to DNS Security provides a strategic roadmap to eliminate this operational blind spot, protect critical infrastructure, and demonstrate regulatory resilience.
