# OT Security, Secure industrial operations and trusted OT data We secure operational technology in energy, utilities, manufacturing and telecom: asset visibility, segmentation, monitoring and OT data integrity, aligned to IEC 62443. ## Outcomes - **Full OT visibility:** Know every asset, connection and vulnerability. - **Reduced operational risk:** Segmented networks and controlled remote access. - **Trustworthy data for AI:** Sensor data proven untampered before agents act. ## Our point of view **In OT, availability and safety come first.** Security controls that work in IT can stop a plant. We design OT security with operations teams, around safety and uptime. ## Where we apply it - **OT risk assessment:** Assets, vulnerabilities and exposure across sites. - **Segmentation & zoning:** IEC 62443 zones and conduits. - **Secure remote access:** Controlled vendor and engineer access. - **OT monitoring:** Threat detection for industrial protocols. - **OT data provenance:** Tamper-evident data for analytics and AI. - **IEC 62443 readiness:** Programmes ready for independent assessment. ## What we deliver - OT asset inventory and risk assessment - IEC 62443 zone-and-conduit design - OT network segmentation and secure remote access - OT threat monitoring and incident response - Cryptographic OT data integrity for AI ## Partner technologies - [Tributech](https://www.nitronedge.com/solutions/agentic-ai-security/tributech/), Agentic AI Security - [Palo Alto Networks](https://www.nitronedge.com/solutions/agentic-ai-security/palo-alto-networks/), Agentic AI Security - [TÜV SÜD](https://www.nitronedge.com/solutions/business-solutions/tuv-sud/), Business Solutions ## Method - 01 Discover (1–2 weeks): Identify the workflow, establish the baseline and define a useful outcome, with a clear view of readiness and risk. - 02 Design (1–3 weeks): Choose the architecture, data boundaries and human checkpoints; agree security and governance up front. - 03 Build (4–10 weeks): Integrate, evaluate and test with the people who will use the system, in weekly sprints on your data. - 04 Evolve (Ongoing): Monitor quality, track value, secure operations and expand what works. ## FAQ ### What is IEC 62443? The international series of standards for securing industrial automation and control systems, covering risk assessment, zones and conduits, and security levels. ### Can OT security be deployed without downtime? Yes. We start with passive visibility and design changes with operations teams so enforcement is introduced in planned windows. ### Can NitronEdge provide OT Security services in Saudi Arabia, the USA or India? Yes. We work with organisations across the Middle East (United Arab Emirates, Saudi Arabia, Oman, Qatar, Bahrain, Kuwait), Africa (South Africa, Nigeria, Kenya, Egypt), the USA, India and Canada. Delivery is remote and on-site, and we design every project around the local data protection and data residency rules.
