NetPeek USB – Network Discovery and Port Scanning Tool

NetPeek USB is a portable network analysis tool that runs directly from a USB flash drive, giving you visibility into what is connected to your network and identifying open ports that could represent potential security entry points. No installation required – just plug in, run, and get results.

What is NetPeek USB?

NetPeek USB is a compact network discovery and port scanning utility packaged on a USB flash drive. It lets IT professionals, network administrators, and security-conscious users quickly audit their local network – finding every device that is connected, identifying which ports are open, and highlighting anything that looks unusual or unexpected.

Because it runs directly from the USB drive, it leaves no trace on the host machine and can be used across different systems without needing to install anything. A single drive and licence key works on both Windows and Linux PCs.

What is Included

Each NetPeek USB package includes:

• A USB flash drive with the NetPeek software pre-loaded
• A perpetual licence tied to your CritchCorp account
• Compatibility with both Windows and Linux systems from a single drive
• All updates to your purchased version included at no extra cost

Key Features

Portable operation: Runs directly from USB – no installation, no admin rights needed on the host machine, no trace left behind.

Network device discovery: Identifies every device currently connected to your network, giving you a clear picture of what is on your infrastructure.

Open port scanning: Checks for open ports that could expose services or represent entry points – useful for both routine audits and investigating suspicious activity.

Cross-platform: A single licence key works across Windows and Linux machines, so you can audit heterogeneous environments with one tool.

Perpetual licence: Buy once, use forever. Current licence holders receive discounted upgrade pricing when moving to the next major version, protecting your investment as the software evolves.

Who It is For

• Routine network audits and inventory checks
• Investigating unexpected devices or connections on a network
• Checking for exposed ports before connecting a new machine to a network
