LONDON – April 28, 2025 – swIDch, a leader in advanced authentication solutions, has been named a “Hot Company” in PLC Security at the 2025 Global InfoSec Awards, presented during RSA Conference in San Francisco. The award recognises swIDch’s innovation in protecting programmable logic controllers (PLCs) and operational technology (OT) systems critical to sectors such as energy, water, and manufacturing.
Now in its 13th year, the Global InfoSec Awards honour the world’s most forward-thinking cybersecurity companies. Winners are selected by a panel of certified security professionals based on their ability to address emerging threats with creative, cost-effective solutions.
swIDch was recognised for its OT authentication technologies — PLC OTAC and OTAC Trusted Access Gateway — which use One-Time Authentication Code (OTAC) technology to generate dynamic, one-way authentication codes without requiring network connectivity. These solutions eliminate authentication vulnerabilities across OT environments — including HMIs, RTUs, and DCS — without overhauling existing infrastructure. Their ability to prevent unauthorised access without certificates or complex password management was praised for its technical and practical strengths.
“swIDch embodies three major features we judges look for to become winners: understanding tomorrow’s threats today, providing a cost-effective solution, and innovating in unexpected ways that can help mitigate cyber risk and get one step ahead of the next breach,” said Gary S. Miliefsky, Publisher of Cyber Defense Magazine.
Having worked with global PLC manufacturers, swIDch continues to advance OT authentication with OTAC Trusted Access Gateway — a solution deployable without PLC vendor support. Field-tested by various institutions, it is now being implemented in real-world industrial environments.
Chang-Hun Yoo, CEO of swIDch, said: “This award reinforces our position in the European OT security market as organisations work to meet NIS2 compliance. Our authentication technology uniquely enables endpoint-level identification and authentication in line with IEC 62443’s FR1 and SR1 requirements.”
