According to CISA Alert AA26-097A (April 2026), Iranian-affiliated advanced persistent threat (APT) actors are conducting exploitation activity targeting internet-facing operational technology (OT) devices, including programmable logic controllers manufactured by Rockwell Automation/Allen-Bradley .
Key Security Concern :
The EU Cyber Resilience Act of 2024 obliges OEMs to certify security-by-design, boosting demand for products with:
Encrypted communications
Built-in anomaly detection
Secure supply chains and domestic semiconductor content
Market Impact :
Cybersecurity threats are a key restraint on PLC adoption
Small manufacturers particularly vulnerable
Vendor security features becoming a critical differentiator
