WiSECURE Establishes Audit Reliability Independent of OT Environments with Compact HSM

WiSECURE, Inc. (Headquarters: Bunkyo-ku, Tokyo; President: Harutaka Mokudai; hereinafter "WiSECURE") plans to unveil application case studies at "Japan IT Week" in the spring of 2026, focusing on a "hardware-based" security architecture that embeds reliability directly into devices for the manufacturing and OT industries.

As an example, the company will introduce an implementation case in a manufacturing environment utilizing the portable OT security tool "ORing Portable Shield (OPS) Pro." This case focuses on ensuring the reliability required for security certification and evaluation processes, achieving an architecture where the integrity of inspection results is maintained even in compromised environments.

"Hardware-Based" Reliability Complementing Software Limitations

With the advancement of smart manufacturing and digital transformation, cyber risks in OT (Operational Technology) environments are rapidly surfacing. Particularly with the spread of international standards such as SEMI E187 and IEC 62443, demands for "tamper resistance" and "auditability" of equipment diagnostic results and operational logs are increasing. Conventional software-centric measures have left a fundamental challenge: the inability to guarantee the authenticity of output results if the inspection terminal itself is compromised.

In response, WiSECURE proposes an approach that guarantees reliability from a "hardware-based" foundation, centering on embedded security modules such as USB-type HSMs (Hardware Security Modules).

In this initiative, WiSECURE's hardware security technology is integrated with ORing's OT scanning technology and security software to be implemented as the portable tool "OPS Pro." This product operates as a USB device and adopts a plug-and-play method that requires no additional software installation. By simply connecting the device, it performs malware scanning and endpoint diagnostics, visualizing security status for both OT and IT, while automatically generating diagnostic reports.

Design Philosophy Enabling Exceptions to "USB Bans"

In manufacturing sites, USBs are generally viewed as a risk for malware intrusion, and usage restrictions are standard practice.

In contrast, OPS Pro is designed as an on-demand security inspection platform that utilizes USB technology.
