TXOne Networks Safeguards Industrial Control Systems with a Single High-Performing Scanning Tool

Jan 25, 2022

Portable Security Pro flexibly fits into the daily security routines of critical enterprise IT infrastructures


Taipei, January 25, 2022 –TXOne Networks, a global leader in ICS and industrial IoT (IIoT) security, presents a new edition of its portable security device designed to scan for and clean up malware on isolated industrial control systems (ICS), as well as to provide secure storage and data transfer. The Portable Security 3 Pro Edition (TMPS3 Pro), a high-performing cybersecurity solution for multiple ICS environments, had been developed together with TXOne Networks’ mother company, Trend Micro, a global cybersecurity leader.


As threats from hostile nations and financially motivated cybercrime gangs mount, ICS security comes under increasing scrutiny from governments and regulators. Portable Security 3 Pro Edition performs malware scanning on target devices during regular maintenance and helps to ensure industrial control systems stay secure. Thus, the new device enables providers of critical infrastructure services to comply with a new range of cybersecurity requirements.


Portable Security 3 Pro can be the first step for OT and ICS supply chain cybersecurity. When new devices are shipped to the factory from the equipment supplier, the inspection can be done in advance through this portable inspection device to ensure and document that the devices are malware-free. Portable Security 3 Pro also enables IT or security teams to securely transfer important files or patches to offline systems and isolated networks.


Flash drives are commonly used to transfer data in an air-gapped environment, but this creates a risk of insider threat. TMPS3 Pro is a device similar to a USB flash drive that combines malware scanning and removal with secure storage for the first time.


In addition to reducing breach and compliance risk, users benefit from the following features:


  • No software installation required – Perform on-demand malware scans on any system without software installation
  • Easy operation – Malware scanning, malware removal, and secure storage in one device that can be used across multiple ICS or endpoint devices. The built-in notification LEDs display the status of the malware scan, making operation quick and convenient.
  • Optimized OT visibility – Collect computer information, Windows Update status, application lists, and other information, preventing shadow OT
  • Centralized management – Get an integrated view of scans occurring across multiple scanning tools and endpoints to meet administrators’ policy needs


The new secure storage feature of Portable Security 3 Pro Edition allows worry-free file transfer between different working environments. All functionalities of the former Portable Security 3 Standard Edition are included, along with the addition of 64GB of secure storage equipped with AES-256 hardware encryption. All files stored in secure storage will be scanned by a built-in anti-malware engine and encrypted on the fly with its AES-256 encryption engine. Only files that have been scanned and confirmed to be malware-free can be saved in secure storage, ensuring that no malicious files will be transferred or stored.


K.S. Pua, CEO of Phison Electronics, said, “Phison and TXOne Networks have been collaborating for several years. In recent years, due to the rise of digitalization, industrial control system (ICS) customers are facing serious network security risks in the process of digital transformation. The high-end customized USB flash drive TMPS3 Pro uses Phison’s customized advanced security architecture to help ICS customers eliminate cybersecurity risks with fast, safe system scans and secure storage. It is a necessary cybersecurity tool in the era of digital transformation.”


Typical use cases of Portable Security 3 Pro are:


  • Periodically scan mission-critical assets for regulatory compliance
  • Inspect incoming or outgoing devices for supply chain assessment
  • Collect and centralize asset information to extend OT visibility
  • Secure file transfer and storage for sensitive data (NEW)


Portable Security 3 Pro makes it much easier for ICS owners and operators to scan for malware and collect asset info on standalone computers as well as air-gapped systems. Unlike traditional anti-virus software, Portable Security scans and cleans up malware without installing scanning software, showing status with an easy-to-understand LED display,“ said Dr. Terence Liu, CEO of TXOne Networks. “Leading companies from various industries and regions are already relying on our solution or considering deployment in their production sites. Among them are companies in the automotive as well as in the defense sector. However, all industries in which work sites run a large amount of operational technologies or have critical manufacturing sites that need to be protected will benefit from the device – for example, companies in the pharmaceutical or semiconductor industries.”
