In the previous two articles, we established two key facts: When devices cannot be updated, Virtual Patching is a necessary risk-mitigation measure. Virtual Patching without AI automation is difficult to sustain over time. So how does this strategy actually work in real industrial environments? Below, we examine three representative industry scenarios to illustrate how Virtual Patching is applied in practice. 1. Semiconductor Manufacturing: One Compromised Tool Can Stop an En

In our previous article, we discussed why microsegmentation is the most practical form of Virtual Patching when devices cannot be updated. However, in real-world environments, an even more critical question quickly emerges: Virtual Patching may be possible — but can it be sustained over time? In most cases, the answer comes down to a single bottleneck: human maintenance cost. Three Real-World Challenges of Traditional Virtual Patching In many enterprise and device environment

In an ideal world, every cybersecurity vulnerability could be patched immediately.But in real industrial environments, “cannot be updated” is often the norm—not the exception . Across semiconductor equipment, medical devices, industrial control systems, and critical infrastructure, there are vast numbers of EOS / EOL (End of Support / End of Life) devices still operating in production lines and clinical settings.These systems remain mission-critical, yet no longer receive sec

In recent years, global expectations for Product Cybersecurity have increased rapidly.Across semiconductor equipment, medical devices, and connected IoT systems, regulators now expect products to demonstrate verifiable security capabilities before shipment. Three major frameworks are driving this shift: SEMI E187 – the first and most widely adopted semiconductor equipment cybersecurity standard published by SEMI EU Cyber Resilience Act (CRA) – the EU cybersecurity regulation

The Invisible Battlefield of Semiconductor Security: When Smart Manufacturing Meets Cyber Threats In Taiwan's proud semiconductor industry, every fab is a highly networked digital ecosystem. From precision wafer loaders, billion-dollar EUV scanners, chemical mechanical polishing (CMP) equipment, to wet process cleaning systems and automated test and packaging equipment, these devices exchange data and coordinate processes through industrial communication protocols such as SEC

Clearing the confusion to help suppliers achieve compliance faster As more semiconductor giants like TSMC push suppliers to adopt SEMI E187 cybersecurity standards, many equipment vendors have started preparing for E187 certification, audit readiness, and compliance workflows. However, Janus has observed in our consulting projects that there are several widespread misunderstandings about SEMI E187, leading many suppliers to spend time and cost in the wrong direction. Here are
