+ShortDescription: Network security scanner — rogue device detector, STP monitor, and connectivity analyser
+Description: |-
+  NetSentinel is a one-stop network diagnostic and security tool for Windows.
+  It combines several tools that previously required separate utilities:
+
+    • Device Fingerprinter  — scans your LAN's ARP table and identifies every
+      device by MAC OUI, hostname, and device type (camera, smart speaker, router, etc.)
+    • Rogue Bridge Detector — captures 802.1D/RSTP BPDUs and flags any device
+      that steals the Root Bridge role and causes periodic 15-45 second outages.
+    • Broadcast Storm Analyser — measures broadcast/multicast packet rates and
+      identifies which device is flooding the network.
+    • IoT Behavioral Baseline — learns normal IoT traffic patterns and raises
+      an alert if your smart fridge starts port-scanning or talking to a C2 server.
+    • Root Cause Correlator — links trace results, storm data, and STP findings
+      into a single plain-English verdict with actionable remediation steps.
+    • Connection Stability Monitor — long-term background ping logger with
+      outage detection, jitter analysis, and a 24-hour stability score.
+    • TCP Port Scanner, OS Fingerprinter, CVE Lookup, DNS Leak Test, Speed Test,
+      ARP spoof detector, DHCP monitor, SNMP poller, and more.
+
+  Most features require Administrator privileges for raw packet capture.
+  Install Npcap (https://npcap.com) for STP, Storm, and ARP modules.
