Authorized DeltaV cybersecurity services:
DeltaV Validated Cybersecurity Assessment (DVCA)
A nonintrusive assessment of your DeltaV DCS and SIS involves gathering DeltaV-specific telemetry from your ProPlus station using native Windows and Emerson tools. We then analyze the data using Armexa’s proprietary technology to evaluate your DeltaV system against industry and Emerson best cybersecurity practices. The DVCA validates critical cybersecurity controls, including security configurations, segmentation, patch status, AV definitions, and DeltaV user management, providing unmatched cybersecurity visibility into your DeltaV control systems.
Cyber-Safety Risk Assessments
Consequence-based OT risk assessments aligned to ISA/IEC 62443-3-2, conducted using Armexa’s proprietary methodologies: CyberHAZOP™, a safety-oriented systematic study, or CyberBowtie™, a streamlined visual alternative. Identifies credible cyber risks tied to real operational, safety, and financial consequences.
Nozomi Networks NIDS Deployment:
Industrial facilities often rely on control systems from various vendors. This turnkey service utilizes the expertise of Armexa and Emerson to deliver a tailored Nozomi Networks deployment that offers comprehensive visibility into the DeltaV DCS, SIS, and third-party control networks. The result is a fully supported solution that provides extensive visibility across the entire facility.
OT Cybersecurity for Capital Projects
Unified cybersecurity design and deployment for greenfield and brownfield projects, aligned to ISA/IEC 62443-2-4. Armexa and Emerson are able to coordinate with cybersecurity embedded at every project phase, including CyberFAT (factory acceptance testing) and CyberSAT (site acceptance testing) to verify security controls before and after commissioning. One point of contact, clear accountability, no handoff gaps.
Managed Services
Ongoing security management for your DeltaV environment without building an internal OT security team. Armexa engineers can provide continuous monitoring, firewall and patch management, and incident response support, keeping your security posture current as your facility and the threat landscape evolve. It’s possible to do with one accountable partner, sustained coverage, and no staffing overhead.

LNG Operator Establishes Formal OT Cybersecurity Baseline for DeltaV Control Environment
A U.S.-based LNG operator engaged Armexa to conduct a Basic Cybersecurity Assessment of its DeltaV control environment, uncovering gaps in user account management, network segmentation, security monitoring, and policy documentation despite strong foundational operational practices. Armexa delivered a structured assessment aligned to the DeltaV Security Manual, NIST CSF, and ISA/IEC 62443, producing a defensible compliance baseline and prioritized remediation roadmap without disrupting plant operations.
