NetSentinel v2.1.2
Security & Verification
Every release is signed and checksummed. Verify before running.
| Check | Result |
|---|---|
| VirusTotal scan | aHR0cHM6Ly9n… |
| SHA256 checksums | SHA256SUMS.txt |
Verify the SHA256 checksum (Windows):
$expected = (Get-Content SHA256SUMS.txt | Select-String 'NetSentinel-Setup').ToString().Split(' ')[0]
$actual = (Get-FileHash 'NetSentinel-Setup-2.1.2.exe' -Algorithm SHA256).Hash.ToLower()
if ($expected -eq $actual) { '✅ OK' } else { '❌ MISMATCH' }Verify the cosign signature (Windows installer):

What it does
One tool that replaces a drawer full of network utilities:
- Rogue device fingerprinting with curated OUI registry (Google, TP-Link, Apple, Amazon, Samsung, LG, PlayStation, Nintendo, Xbox, Roku, Netgear, Asus)
- STP/BPDU rogue Root Bridge detection
- Broadcast & multicast storm analysis
- IoT Behavioral Baseline — learns normal device traffic, alerts on deviations
- Root Cause Correlator — distinguishes ISP fault from local network fault
- Network Grade (A–F) across 8 dimensions — uptime, latency, jitter, DNS, speed, safety, STP, storm
- ISP Accountability Report — HTML export with MTR hop table and outage log for support tickets
- How-to-Fix context menus on every scan result
- Hidden SSID and co-channel WiFi interference detection
- Live ping + DNS latency correlation
- On-demand diagnostics: speed test, DNS leak, traceroute, public IP
- Long-term background connectivity logger with stability scoring
- TCP port scanner, OS fingerprinter, CVE lookup, MTR, and more
- HTML, JSON, CSV, Nmap XML report export
