Windows utilities, built by a working sysadmin

One exe. No installer. No account. No telemetry.

Network scanning, USB inspection, PXE deployment and country-level outbound blocking for IT admins who need something that runs on a locked-down box today. Every tool is free to use indefinitely. Pay once if it earns its keep.

Four tools, one rule: it has to work on a clean machine

Each download is the whole product. The trial prompt is the only thing a license removes.

Why pay when the freeware exists

The free tools are good. These are built for the day the free tools cannot be used.

Air-gapped lab. Customer site with no admin rights. A box that failed the install because Java or .NET was not there. An audit that asks what the scanner phones home to. Every product here was written by an IT admin who hit those walls.

Single executableNo .NET, no Java, no installer. SubnetSweep and USB Probe are a bare zip; PXE Forge is a 4 MB setup.
Works fully offlineVendor database ships inside. License verification is local. No update nag, no crash reporter.
Signed and hashedPublisher ITITSOLUTION SOFTWARE LLC on the Authenticode signature. SHA256 published beside every download.
Pay once, own the versionA key covers every 1.x release. No subscription, no seat audit emails. Volume and site licenses for teams.
