【SEMI E187 Workshop Recap】From Equipment Compliance to Trust Across the Semiconductor Supply Chain

The “SEMI E187 Semiconductor Equipment Cybersecurity Compliance Workshop” has successfully concluded after being held in Taichung, Kaohsiung, and Hsinchu. Focusing on semiconductor equipment cybersecurity compliance, supply chain requirements, and implementation challenges, the workshop brought together industry experts, leading manufacturers, and equipment vendors to share insights from the perspectives of standard development, supply chain needs, implementation cases, and international trends.

As global supply chain cybersecurity requirements continue to rise, SEMI E187 is gradually becoming an important cybersecurity threshold for semiconductor equipment delivery and supply chain collaboration. For equipment vendors, understanding the standard, building verification capabilities, and implementing cybersecurity measures effectively have become key industry priorities.

Through industry requirement sharing, standard trend analysis, equipment vendor case studies, and cybersecurity solution demonstrations, this workshop helped participants better understand the direction of SEMI E187 implementation. Overall, SEMI E187 is no longer merely a cybersecurity checklist for equipment. It is becoming an important foundation for establishing trust across the global semiconductor supply chain.

Below are three key observations from the workshop for industry partners' reference.

Insight 1｜SEMI E187 Is Evolving from a Compliance Requirement into a Common Language of Supply Chain Trust

Cybersecurity challenges in the semiconductor industry are no longer limited to a single piece of equipment, factory, or supplier. They have become shared risks across the entire ecosystem.

As global customers increasingly require equipment to demonstrate verifiable security capabilities, the value of SEMI E187 is no longer just about passing an assessment. It provides a common standard for equipment vendors, system integrators, fabs, and supply chain partners to discuss risks, evidence, and responsibilities.

In other words, the true value of SEMI E187 lies in transforming “we believe it is secure” into “it can be verified and trusted.”

Insight 2｜International Cybersecurity Regulations and Industry Standards Are Converging, and Equipment Vendors Must Prepare Early

The discussions in this workshop also showed that semiconductor equipment cybersecurity will no longer be driven only by individual customer requirements. It will also be shaped by international cybersecurity regulations, supply chain risk management, and procurement systems.

For example, although regulatory trends such as the Cyber Resilience Act (CRA) differ from SEMI E187 in scope and positioning, they share a similar underlying principle: products and equipment must continuously demonstrate manageable, traceable, and verifiable cybersecurity capabilities throughout design, delivery, and maintenance.

This means equipment vendors will face responsibilities beyond a one-time pre-shipment check. Cybersecurity will need to be addressed across product design, vulnerability management, software updates, network communications, log retention, and lifecycle management.

Insight 3｜The Next Step for Semiconductor Cybersecurity Is Moving from Point Solutions to Ecosystem Collaboration

The implementation of SEMI E187 cannot rely on a single company or department alone. Equipment vendors bring equipment engineering expertise, cybersecurity companies provide risk governance and technical implementation capabilities, while fabs and OSATs play an important role in driving demand and standardizing verification expectations.

Therefore, the most effective model going forward will not be equipment vendors working alone, nor simply purchasing cybersecurity tools. Instead, it will require a collaborative model among equipment vendors, cybersecurity partners, verification bodies, and industry customers.

This also means SEMI E187 implementation will move beyond “preparing documents” toward building sustainable cybersecurity capabilities.

Practical Challenges Observed from the Workshop

Through on-site exchanges and post-event feedback, we observed that many companies are facing several common questions:

• How can companies determine how far their equipment currently is from meeting SEMI E187 requirements?

• How can they prepare technical evidence acceptable to customers and third-party verifiers?

• How can they improve network security without significantly changing existing equipment architecture?

• How can they prevent cybersecurity requirements from slowing down R&D, delivery, and customer acceptance timelines?

These are not merely cybersecurity questions. They are also closely tied to whether equipment vendors can rapidly align with global semiconductor supply chain requirements and remain competitive.

Feedback from the post-event survey also indicates that while the market is not yet fully mature, industry demand is gradually taking shape. Many equipment vendors remain in the assessment and preparation stage, with strong interest in verification processes, implementation methods, technical evidence, and supporting resources.

How Janus Cyber Helps Equipment Vendors Implement SEMI E187

Janus Cyber is committed to helping enterprises implement equipment cybersecurity and SEMI E187 compliance. Our services cover compliance gap analysis, evidence documentation preparation, equipment network protection, and automated micro-segmentation deployment.

We help equipment vendors move from understanding standards and assessing current conditions to technical implementation, gradually building verifiable and sustainable cybersecurity capabilities. This enables equipment to move beyond “meeting requirements” toward becoming “trusted.”
