Military-grade USB protection: How Hunna and Glasswall secure data in the field

Providing file-based cybersecurity protection while in the field is a major challenge faced by many government, military and intelligence agencies. The nature of fieldwork makes it difficult for reactive detection-based solutions, such as antivirus engines, to keep up-to-date with today's sophisticated threats.

The Hunna USB Sanitizer is a portable, air-gapped solution that integrates Glasswall Content Disarm and Reconstruction (CDR) technology to ensure files and data imported or exported via USB are clean and safe. Built to the highest standards of security, the Hunna USB Sanitizer delivers military-grade safety for complete peace of mind as part of a zero-trust approach to file-based cybersecurity.

How it works

Hunna employs a scan/copy process that transfers data from one USB through the system and saves the trusted data to another. The selection of antivirus engines is randomized for each scan, ensuring that it remains unpredictable for potential attackers to determine which antivirus has been used to search for known malware in files and documents. They are then processed through the Glasswall CDR engine, which instantly cleans and rebuilds files to match their known good manufacturer’s specification, stripping away anything that doesn’t conform.

This proactive approach automatically removes malware and exploits from the file. The safe files are filtered through a whitelist before being copied to a target USB and signed. The target memory is also signed.

Using Glasswall’s industry-leading, patented CDR technology, Hunna System USB Sanitizer provides military-grade file safety via a simple, intuitive user interface. It supports a wide range of disk formats, including FAT32, ExFAT, NTFS, EXT4, EDF (DVD) and ISO 9660 (CD), and can protect against threats hidden within 96.4% of most common business files, including Binary Office, Open XML Office, PDF, PNG, JPEG, BMP, TIF and GIF.
