Recursive Subdomain Discovery for
Deep Infrastructure Visibility

Identify deeply nested hostnames often overlooked with black-boxed ASM products. The more embedded a hostname is within your infrastructure, the higher the likelihood it remains unmonitored. This module replicates attacker techniques tailored to your company to help you uncover and secure high-risk assets.

Uncover Hidden Dependencies undefined

01 Uncover Hidden Dependencies

Expose deeply embedded hostnames within your infrastructure that are often unknown to your team, ensuring no critical asset remains unmonitored.

Detect Forgotten and Legacy Systems undefined

02 Detect Forgotten and Legacy Systems

Identify neglected systems and legacy hostnames buried in your architecture, which may have been abandoned but still pose significant security risks.

Prioritize High-Risk Assets undefined

03 Prioritize High-Risk Assets

Focus on assets attackers are most likely to target, such as deeply nested hostnames that often lack modern security controls, providing a clear path to strengthen your defenses.

Secure the Full Depth of Your Attack Surface

Recursive DNS brute force is essential for uncovering deeply nested subdomains and multi-level hostnames that attackers often target. By identifying overlooked assets and legacy systems, this approach provides complete visibility into your attack surface.

Gain Greater Visibility and Eliminate Legacy Risks

Recursive enumeration provides complete visibility into multi-level subdomains, legacy systems and different environments. By identifying and securing these overlooked assets, security managers can eliminate recurring risks and strengthen the integrity of their organization's attack surface.

Gain Greater Visibility and Eliminate Legacy Risks
Reveal Hidden Multi-Level Vulnerabilities

Reveal Hidden Multi-Level Vulnerabilities

Overlooked assets are often buried multiple levels deep within your infrastructure, where legacy systems and vulnerabilities tend to reside. Recursive DNS brute force reveals these hard-to-find hostnames, ensuring no critical component is left unmonitored or unprotected.

Match Attacker Persistence Across All Levels

Match Attacker Persistence Across All Levels

Attackers don't stop at the first layer of your infrastructure, and neither should you. Recursive DNS brute force mirrors adversary tactics, uncovering hidden vulnerabilities across all subdomain levels so you can stay ahead and secure your assets proactively.

Full Recursive Coverage

Full Recursive Coverage

Identify sub-subdomains across multiple levels, uncovering deeply nested hostnames and infrastructure components often overlooked by traditional enumeration tools.

High-Probability Brute Forcing

High-Probability Brute Forcing

Focus on the most likely hostname variations at each level with optimized wordlists, significantly reducing noise and improving the efficiency of the enumeration process.

Flexible Wordlist Customization

Flexible Wordlist Customization

Use built-in wordlists crafted from real-world analysis or upload custom wordlists tailored to your organization's naming conventions for precise and targeted results.

Wildcard Filtering

Wildcard Filtering

Leverage trusted resolvers, daily validated resolver lists, and wildcard filters to ensure the accuracy of discovered hostnames while eliminating false positives.
