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]
$actual   = (Get-FileHash 'NetSentinel-Setup-2.2.3.exe' -Algorithm SHA256).Hash.ToLower()
if ($expected -eq $actual) { '✅ OK' } else { '❌ MISMATCH' }

Verify the cosign signature (Windows installer):

cosign verify-blob \
  --bundle NetSentinel-Setup-2.2.3.exe.bundle \
  --certificate-identity-regexp "https://github.com/ossianericson/netsentinel/.*" \
  --certificate-oidc-issuer "https://token.actions.githubusercontent.com" \
  NetSentinel-Setup-2.2.3.exe

Verify the cosign signature (MSIX):

cosign verify-blob \
  --bundle NetSentinel-2.2.3.msix.bundle \
  --certificate-identity-regexp "https://github.com/ossianericson/netsentinel/.*" \
  --certificate-oidc-issuer "https://token.actions.githubusercontent.com" \

NetSentinel v2.2.3

v2.2.3 (current)

  • Alerts you actually care about now surface first — the Home "Action needed" card was quietly showing the five oldest unread alerts instead of the most urgent ones
  • Eight core alerts — gateway loss, mesh node drop-off, modem signal drop, unreachable infrastructure and more — are now switched on by default for new installs, instead of arriving silent
  • A repeated outage on the same device no longer spams a fresh alert every two minutes; it fires once and resolves once, the way it always should have
  • Fixed a bundled plugin (like the 5G modem) silently going stale after an update and quietly stopping monitoring with no obvious error
  • Fixed multicast/broadcast groups being tracked and even flagged as "infrastructure" as if they were real devices on your network
