Why you should consider DNS Brute Force

Simulating attacker behavior for finding subdomains via DNS Brute Force leverages custom or built-in wordlists leading to internal systems, third-party integrations, and overlooked assets with verified, false-positive-free results—giving your security team the same insights attackers would use to exploit your infrastructure.

Tailored Infrastructure Discovery undefined

01 Tailored Infrastructure Discovery

Adapt to each organization's unique structure by using custom wordlists that align with internal naming conventions, ensuring comprehensive and relevant subdomain discovery.

Verified Assets undefined

02 Verified Assets

Eliminate false positives with cross-checked DNS results—if a subdomain is found, it definitively exists, providing your team with reliable, actionable intelligence.

Attacker-Driven Enumeration Tactics undefined

03 Attacker-Driven Enumeration Tactics

Mimic real-world attacker techniques with DNS Brute Forcing module, exposing the same hidden assets and vulnerabilities adversaries target.

Why is DNS Brute Force Essential for ASM

It uncovers hidden subdomains and overlooked assets that traditional tools miss, revealing internal systems and third-party connections. This attacker-simulated approach delivers verified, false-positive-free results, ensuring complete visibility and greater security intelligence.

Infrastructure Discovery of Unknown Assets

Uncover all active and unknown subdomains across your organization's root domains using DNS brute force with custom or built-in wordlists. This approach thoroughly identifies internal systems, third-party integrations, and more, providing an accurate view of your external attack surface.

Infrastructure Discovery of Unknown Assets
High-Fidelity Enumeration with Verified Results

High-Fidelity Enumeration with Verified Results

Eliminate false positives by cross-verifying discovered subdomains with a curated list of trusted DNS resolvers and advanced wildcard filtering. This guarantees that every detected subdomain exists, delivering actionable intelligence that security teams can confidently prioritize and address.

Adversary Simulation for Real World

Adversary Simulation for Real World

Mimic real-world attacker behavior by aggressively brute-forcing DNS records to uncover hidden and vulnerable assets. This proactive strategy allows security teams to identify and remediate the same weak points adversaries target, strengthening overall security posture before exploitation occurs.

High-Accuracy Discovery

High-Accuracy Discovery

Utilizes a daily validated resolver list and trusted cross-checks to ensure precise and reliable subdomain enumeration with minimal false positives.

Customizable Wordlist Support

Customizable Wordlist Support

Enhance discovery by using the built-in wordlist or uploading a custom list tailored to your organization's unique naming conventions.

Wildcard Filtering

Wildcard Filtering

Automatically filters out wildcard DNS records to eliminate false positives and deliver cleaner, more actionable results.

Hyperscalable Enumeration

Hyperscalable Enumeration

Effortlessly brute-force subdomains across thousands of domains simultaneously, accelerating large-scale attack surface analysis.

How Discovery through DNS Brute Force Works

This module uses built-in or custom wordlists, cross-verifies results with trusted resolvers, and filters out false positives to provide accurate, actionable insights into your organization's external attack surface.

Provide Your Domains & Wordlists

Start by supplying a list of domains to enumerate. Use the built-in wordlist or upload a custom one tailored to your organization's naming conventions for more precise discovery.
