FreeNetEnumerator

FreeNetEnumerator is a free network scanning and reconnaissance software developed by Nsauditor / Nsasoft LLC. It is primarily designed to discover, map, and list (enumerate) computers and servers within a Windows domain or network.

The tool serves as a standalone, simplified version of the broader network auditing capabilities found in the developer’s premium software, Nsauditor. Core Functionality

The software functions by querying the network and filtering targets based on user-defined parameters. It allows administrators or security professionals to scan for specific types of network infrastructure, including:

All Computers: Lists every active workstation and machine connected to the domain.

Microsoft SQL Servers: Isolates and identifies database servers running on the network.

Domain Controllers: Identifies Primary Domain Controllers (PDC) and Backup Domain Controllers (BDC) managing the network security.

Primary Domains: Maps out the top-level domain structures present. Dual-Use Nature in Cybersecurity

Because FreeNetEnumerator provides a structured, easy-to-read map of a network’s high-value targets (like SQL databases and domain controllers), it is recognized as a dual-use tool:

Ethical Hacking & Audit: Network administrators and penetration testers use it to quickly evaluate network visibility and ensure security configurations are working. It is often referenced in cybersecurity training curricula, such as older versions of the Certified Ethical Hacker (CEH) certification.

Malicious Reconnaissance: Malicious actors or automated worms can use identical enumeration techniques to find vulnerable servers to target for lateral movement or data extraction.

Because it targets critical enterprise assets, some corporate antivirus software or Intrusion Detection Systems (IDS) may flag the installer or executable as a Potentially Unwanted Program (PUP) or a generic riskware/hacktool.

If you are looking at this for a specific project, let me know:

Are you trying to secure your network or perform a penetration test?

Do you need alternative, more modern tools (like Nmap or BloodHound) for active directory discovery?

Did your antivirus flag this file, and you are trying to verify if it is safe?

I can provide specific configuration guides or safety checks based on what you need. How it works: FreeNetEnumerator
