Scan Any Endpoint Without Installing Anything
Plug in, scan, unplug. Agentless malware scanning for any USB port.
Agentless malware scanning and asset discovery from a USB device. Supports 80+ operating systems from Windows 2000 through the latest Linux distributions.
81.9% of USB suspicious activity in OT environments involves file transfers. Your air-gapped systems need protection that works without installation.
Portable Inspector plugs into any USB port to scan for malware, collect asset information, and verify system integrity without software installation, or system modifications. One device covers Windows 2000 SP3 through Windows 11, Windows Server, Windows Embedded, and major Linux distributions. The Pro Edition adds AES-256 hardware-encrypted storage for validated file transfer into air-gapped environments, creating a complete data hygiene solution for constrained operations.
Security for Systems Nobody Else Can Reach
Every OT environment has systems that security tools cannot touch. Air-gapped controllers that will never see a network connection. Legacy workstations that reject modern agents. Test systems nobody documented. These assets run production, and they run unprotected. Portable Inspector changes that equation. Plug into any USB port, scan the system, collect asset data, and unplug. No installation. No modification. No trace left behind. When you need to move files into those environments safely, the Pro Edition scans and encrypts in one step.
Zero Installation. Zero Modification.
Plug into any USB port to begin scanning. No software, no agents, no credentials required. Unplug when done.
25 Years of OS Coverage
Windows 2000 SP3 through Windows 11, Windows Server 2003 through 2025, and major Linux distributions.
AES-256 Encrypted Transport (Pro)
Hardware-encrypted secure storage scans files during transfer. Only verified malware-free content enters your environment.
Built-In Asset Intelligence
Every scan automatically collects hardware specs, OS details, installed applications, and patch status.

OT Security Challenges
Critical challenges that Portable Inspector is purpose-built to solve
01 / 03
Isolated Systems Still Get Infected
Air-gapped SCADA systems and safety controllers cannot connect to update servers, but USB devices, contractor laptops, and maintenance ports provide persistent entry points. 81.9% of USB suspicious activity involves file transfers that carry malware directly to isolated production systems (Honeywell 2025).

Agentless Scanning Engine
Malware Detection Without Installation
Portable Inspector runs its scanning engine directly from the USB device, requiring zero installation on the target system. Malware detection and removal are performed without rebooting or modifying the host system, enabling on-demand scans whenever and wherever needed.
- No software installation on target systems
- No reboot required during or after scanning
- On-demand malware scans for any endpoint
- Supports Windows 2000 through Windows 11 and Linux
The only industrial USB scanner covering Windows 2000 to Windows 11
Portable Scanning vs. Traditional AV Workstation
Many facilities rely on a dedicated AV PC to scan USB devices before use. This approach creates bottlenecks, requires maintenance, and cannot reach systems in the field.
Portability
Fixed AV workstation in one location. Devices must be carried to the scanning PC, creating delays and compliance shortcuts.
USB-form-factor device carried to any asset. Scan where the work happens, not where the PC sits.
System Impact
AV PC requires its own OS updates, signature maintenance, and IT support. Another system to manage.
Zero installation on scanned systems. No software, no agents, no traces left behind. Pattern updates via ElementOne.
Asset Discovery
Scans media only. No visibility into the endpoint being served. Separate tools needed for asset inventory.
Scans media and collects asset information, installed applications, patch status, and system specs in one pass.
Chain of Custody
Scan results stored on the AV PC. No encrypted transport. No tamper-evident audit trail.
Pro Edition provides AES-256 hardware encryption for secure file transfer with tamper-evident logging.
