swIDch Launches OTAC Trusted Access Gateway (TAG) to Secure OT Systems Without Modifications to Legacy Devices

LONDON - February 10, 2025 - swIDch, a leader in cybersecurity for operational technology (OT), has unveiled its innovative OTAC Trusted Access Gateway, designed to provide robust, centrally managed user authentication for programmable logic controllers (PLCs) and other OT systems without requiring any modifications to legacy devices.

As cyber threats targeting critical infrastructure rise, securing OT environments is more urgent than ever. Studies show that 80% of vulnerabilities exist deep within ICS networks, requiring adversaries to first gain access to OT systems to exploit them. Alarmingly, 81% of OT security breaches stem from weak or stolen passwords, many used on PLCs. Static passwords and outdated access control methods leave these critical systems vulnerable, threatening operational continuity and safety.

The OTAC Trusted Access Gateway, addresses this challenge with a simple-to-deploy, dynamic one-time authentication code (OTAC) system that effectively counters evolving threats. By generating unique, non-reusable codes for each session, it ensures strong authentication without the need for expensive or complex system overhauls. The device connects seamlessly to existing PLCs, eliminating the need for any changes to the hardware or OT network processes.

In addition to enhancing security, the OTAC Trusted Access Gateway, offers centralised user authentication management and comprehensive access logs, enabling organisations to efficiently track user and device activity. Unlike traditional systems such as public key infrastructure (PKI) or biometric authentication, which may require additional resources or complex setup, its one-way dynamic authentication operates smoothly, even in offline environments.

"The OTAC Trusted Access Gateway, is a game-changer for OT security. It secures PLCs and critical systems without any modifications, offering dynamic authentication codes, centralised management, and enhanced access logs-all at a fraction of the cost. As cyber threats escalate, our revolutionary new solution ensures your legacy systems remain protected with minimal disruption," said Chang-Hun Yoo, CEO of swIDch.
