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]
$actual   = (Get-FileHash 'NetSentinel-Setup-2.1.15.exe' -Algorithm SHA256).Hash.ToLower()
if ($expected -eq $actual) { '✅ OK' } else { '❌ MISMATCH' }

Verify the cosign signature (Windows installer):

cosign verify-blob \
  --bundle NetSentinel-Setup-2.1.15.exe.bundle \
  --certificate-identity-regexp "https://github.com/ossianericson/netsentinel/.*" \
  --certificate-oidc-issuer "https://token.actions.githubusercontent.com" \
  NetSentinel-Setup-2.1.15.exe

Verify the cosign signature (MSIX):

cosign verify-blob \
  --bundle NetSentinel-2.1.15.msix.bundle \
  --certificate-identity-regexp "https://github.com/ossianericson/netsentinel/.*" \

NetSentinel v2.1.15

v2.1.15 (current)

Added

  • Settings page category chip bar (All | Appearance | Monitoring | Alerts | Integrations | Advanced) with per-session persistence
  • ui/guided_tour.py — 5-step first-run guided tour; auto-starts on first launch, restartable from Settings → Advanced
  • ui/widgets/inventory_dialogs.py — 4 dialog classes extracted from inventory_page.py (file budget relief)
  • ui/widgets/scan_radar_widget.py — phosphor-green radar sweep animation on Home page during scan
  • Empty state cards with inline CTA on 8 pages; right-click context menus on all 19 scan result tables; loading states on scan-dependent pages
  • RULE-T2 worker lifecycle tests for 22 workers; behavioral integration tests for 18 additional pages

Fixed

  • Devices table blank after scan (DeviceInfo.get() eager-eval crash); table now preserved atomically during scan
  • Discovered Devices showing only raw IPs on restart — seeded from network map cache
  • Three Inventory scan bugs: vendor persistence, mesh enrichment, blank cells on re-scan
  • Settings page redundant left sidebar removed; all unparented QTimer.singleShot replaced (RULE-WIN5)
