Overview of the Announcement
On Tuesday, SSH Communications Security announced that its PrivX OT (Operational Technology) solution is now available for deployment on Nokia’s Industrial Edge (MXIE) on‑premises compute platform. The move represents a strategic collaboration between a specialist in defensive cybersecurity for humans, systems, and networks and a global leader in telecommunications and industrial infrastructure. By joining forces, the two companies aim to modernize and secure industrial environments and critical infrastructures that are undergoing rapid digital transformation.
Nokia Industrial Edge MXIE Platform
Nokia’s ECE MXIE is described as a robust, future‑ready edge solution purpose‑built to accelerate the digital transformation of industrial OT and Cyber‑Physical Systems (CPS) environments. MXIE provides the compute, storage, and networking foundation needed to run a wide variety of industrial applications at the edge, close to where data is generated and acted upon. Its architecture emphasizes reliability, scalability, and low latency, making it well‑suited for factories, utilities, transportation networks, and other mission‑critical sites.
Integration via Digital Automation Cloud
Through the Nokia Digital Automation Cloud (DAC) Application Catalog, MXIE supports a diverse range of industrial applications, and SSH’s PrivX OT solution now appears as a certified offering within this catalog. The DAC simplifies deployment, lifecycle management, and updates for third‑party software, allowing OT organizations to add PrivX OT with minimal engineering effort. This plug‑and‑play approach reduces the time‑to‑value for security enhancements while maintaining the integrity of the edge environment.
PrivX OT Core Capabilities
PrivX OT functions as a single digital gatekeeper that manages Secure Remote Access (SRA) to hundreds of IT and OT systems. It enforces Zero Trust principles, granting access only after continuous verification of identity, device health, and context. Access is delivered just‑in‑time, meaning permissions are granted for the exact duration needed to complete a task and then automatically revoked. Role‑based access controls (RBAC) further refine who can do what, while integrated job‑approval and ticketing workflows ensure that every access request is traceable and authorized.
Just‑in‑Time Access and Zero Trust
The just‑in‑time model eliminates standing privileges, a common attack vector in legacy OT environments. By combining Zero Trust with protocol‑agnostic connectivity, PrivX OT can broker connections across heterogeneous protocols—such as Modbus, DNP3, OPC UA, and proprietary industrial buses—without requiring changes to the underlying devices. Secure file transfers are also protected, enabling engineers to move configuration scripts, logs, or firmware updates safely between the corporate IT network and the OT shop floor.
Centralized Control and Integration Benefits
Centralized management through PrivX OT provides a unified console for local, remote, and third‑party personnel to request, approve, and monitor access to industrial, commercial, and critical‑infrastructure sites. This centralization streamlines governance, reduces administrative overhead, and improves productivity by eliminating the need for multiple, siloed access tools. Moreover, the solution is designed to keep costs, complexity, and operational disruption low while maintaining high visibility into who is accessing what and when.
Monitoring, Auditing, and Compliance
PrivX OT incorporates extensive monitoring and auditing capabilities, including detailed audit trails, real‑time session monitoring, and session recording. These features give security teams full visibility into user activity and access patterns, enabling rapid detection of anomalous behavior. The audit data supports compliance with key industry standards such as the NIST Cybersecurity Framework (CSF) 2.0 and IEC 62443, helping organizations satisfy regulatory requirements and demonstrate a strong security posture across both IT and OT domains.
Operational Efficiency and Safety
By delivering secure, controlled access and maintaining a clear record of all interactions, PrivX OT contributes to the safety, availability, and reliability of cyber‑physical systems. Engineers can perform maintenance, troubleshooting, and upgrades without exposing the plant to unnecessary risk. The solution’s scalability allows it to be deployed across distributed infrastructures—from a single facility to a multinational enterprise—while preserving consistent security policies and operational efficiency.
Previous Partnership with Cinia
The announcement builds on an earlier collaboration: last May, SSH and Finnish systems integrator Cinia signed a reseller agreement that enables both parties to deliver high‑security systems and services to a broader customer base. The agreement covers SSH’s full portfolio, including access management for critical IT and OT resources, high‑performance quantum‑safe remote data transmission, password and SSH‑key management, and encrypted messaging, video calls, and emails. This partnership expands SSH’s market reach and reinforces its commitment to providing end‑to‑end security solutions.
Strategic Implications and Future Outlook
The availability of PrivX OT on Nokia MXIE signals a growing recognition that edge computing must be accompanied by equally robust security controls, especially in OT environments where safety and continuity are paramount. By integrating a Zero Trust, just‑in‑time access platform directly into a leading industrial edge solution, SSH and Nokia are offering customers a turnkey path to modernize legacy OT security without rip‑and‑replace of existing equipment. As industries continue to adopt IoT, AI, and automation at the edge, solutions like PrivX OT that combine strong identity controls, comprehensive auditing, and seamless integration are likely to become foundational elements of a resilient cyber‑physical security strategy.
