NetSentinel Project

NetSentinel Project is an open-source software publisher focused on network security tooling, distributing its work through its public repository on GitHub. The publisher's catalog currently consists of a single flagship product, NetSentinel, a network security scanner designed to help administrators and security-conscious users maintain visibility and control over their local network environments. The software combines three core capabilities within one package: a rogue device detector that identifies unauthorized or unknown hosts connected to a network, an STP monitor that observes Spanning Tree Protocol activity to help uncover topology changes or potentially malicious interference with switching infrastructure, and a connectivity analyser that assists in diagnosing link and reachability issues across network segments. Together, these functions position NetSentinel as a practical tool for network auditing, intrusion awareness, and day-to-day troubleshooting. Typical use cases include small and medium-sized organizations seeking to detect rogue access points or unmanaged devices before they become security liabilities, IT teams monitoring switch behavior for signs of misconfiguration or attack, and technically inclined home users who want a clearer picture of what is happening on their own networks. Because the project is hosted openly on GitHub, users can inspect the source code, track development activity, and contribute improvements, which is characteristic of community-driven security software. As a catalog entry, NetSentinel Project represents a focused, single-product publisher whose offering sits squarely within the network security and administration category, addressing device discovery, protocol monitoring, and connectivity diagnostics through one integrated scanning solution rather than a broad suite of unrelated utilities.
