Encrypted DNS Detection

Encrypted DNS Detection Intelligence

The following page provides information on the Encrypted DNS Detection indicator drivers included in Netify's Intelligence engine.

Overview

While DoT, DoH, and DoQ are effective tools for securing DNS traffic against eavesdropping, they create a blind spot for security infrastructure. By tunneling DNS requests through TLS, HTTPS, or QUIC, these protocols can undermine internal access controls and make it difficult for organizations to manage cybersecurity risk.

Other Intelligence Info

The DoH scanner indicator driver provides a dynamic defense layer by automatically detecting new or hidden DoH servers in real-time. This driver uses advanced behavioral analysis to identify the unique fingerprint of DoH traffic. This proactive approach is critical for blocking private DoH proxies, home-grown resolvers, and malware-driven command-and-control (C2) channels.

To protect enterprise and school networks, our the DoH/DoQ server indicator driver utilizes a curated list of well-known DNS-over-HTTPS (DoH) and DNS-over-QUIC (DoQ) servers to prevent users or malware from bypassing local security policies.
