Expanding Cybersecurity Capabilities for Modern Control Systems
Emerson has formed a strategic partnership with Armexa to enhance cybersecurity support for customers using the DeltaV automation platform. This collaboration gives industrial automation operators access to a single, authorized cybersecurity service provider, which simplifies vendor coordination and improves project schedules. Moreover, it helps facilities increase resilience across their operational technology (OT) environments.
Armexa’s OT Cybersecurity Expertise Across Key Industries
Armexa brings extensive experience in OT cybersecurity for energy plants, LNG terminals, chemical facilities, pharmaceutical operations, utilities, and large manufacturing sites. The company combines Emerson-approved technologies with established best-practice methods to deliver consistent security governance. This approach helps operators maintain a unified cybersecurity standard across PLC, DCS, and factory automation systems.
Delivering Streamlined Cybersecurity Management for DeltaV Facilities
According to Jacob Marzloff, CEO of Armexa, the partnership allows DeltaV users to experience simplified on-site cybersecurity management. He emphasized that all offered services are authorized, fully integrated, and designed specifically for the realities of OT environments. His comments reflect a broader industry trend where operators seek cohesive solutions instead of fragmented security tools.
Initial Cybersecurity Services for DeltaV Automation Platforms
As an authorized Emerson service provider, Armexa now offers several foundational services to DeltaV customers. Its baseline cybersecurity assessment delivers a cost-effective and non-intrusive review of OT environments, including DeltaV DCS and SIS architectures. In addition, Armexa provides consequence-driven cybersecurity risk assessments based on the ISA/IEC 62443 standards.
Advanced Risk Analysis Through CyberHAZOP and CyberBowtie
Armexa uses two structured methodologies during its consequence-based evaluations. CyberHAZOP applies a safety-focused, systematic model to examine OT network vulnerabilities. CyberBowtie offers a simplified, visual risk-analysis alternative. Both approaches help operators understand threat paths more clearly, which is essential for critical control systems in oil and gas, chemicals, and large-scale manufacturing.
Turnkey OT Intrusion Detection and Ongoing System Optimization
The company will also support the deployment and maintenance of OT intrusion detection systems. These turnkey services enable rapid installation, precise tuning, and continuous improvement. As facility networks grow more complex, this type of intrusion monitoring becomes a core requirement for reliable automation and process control.
Joint Solutions for Capital Projects and Secure System Design
For capital projects, Emerson and Armexa combine their strengths to design and implement cybersecurity solutions that align with ISA/IEC 62443-2-4 requirements. This joint approach ensures that new control systems integrate secure architecture from the start rather than relying on later retrofits. In my experience, early-stage security planning significantly reduces future operational risks and unplanned downtime.
Supporting Operators in a Rapidly Changing Threat Landscape
Alexandre Peixoto, Director of Cybersecurity at Emerson, noted that industrial companies face increasing pressure to maintain robust security programs. He explained that a unified supplier approach streamlines procurement and enables consistent application of security policies across essential OT infrastructure. This message aligns with broader industry standards that emphasize lifecycle security for PLC, DCS, and SCADA systems.
Application Scenarios and Real-World Use Cases
1. Refinery Control System Hardening
A refinery using DeltaV DCS could apply CyberHAZOP analysis to identify potential attack paths targeting burner management or emergency shutdown systems.
2. LNG Terminal Network Segmentation
An LNG terminal may deploy Armexa’s intrusion detection system to monitor segmented OT networks that manage tank pressure, temperature, and loading operations.
3. Pharmaceutical Batch Control Security
Pharmaceutical plants using distributed batch control systems can benefit from baseline assessments to ensure compliance with regulatory cybersecurity expectations.
4. Power Utility OT Governance
Utilities can integrate ISA/IEC-compliant security policies into new capital expansion projects, improving long-term reliability for generation and distribution assets.
