Firewall and Intrusion Prevention Systems
Go beyond traditional protocol and port inspection to filtering malware at the application level, providing an advanced first line of defence against threats.
Rugged Connectivity with Solutions Engineered for Harsh Environments
As industrial control systems (ICS) become increasingly connected, the risk of cyber threats targeting Operational Technology (OT) environments continues to grow. CSE WAF delivers advanced OT cybersecurity solutions designed to protect critical infrastructure while maintaining system availability and performance.
In partnership with Siemens, we deploy industrial Next Generation Firewall (NGFW) and intrusion detection technologies purpose-built for harsh environments. These solutions go beyond traditional perimeter security by providing advanced protection from deep packet inspection (DPI) for industrial protocols and application-level filtering and threat detection, to network segmentation between IT and OT environments and secure remote access control and policy enforcement.
Aligned with industry frameworks such as IEC 62443, our solutions are designed to safeguard industrial systems while supporting operational continuity and compliance.
Applications
Power Generation and Distribution
Used to securely segment substations, enforce role-based access to Intelligent Electronic Devices (IEDs), and enable safe remote access for maintenance and diagnostics, Siemens NGFWs protect critical control systems from cyber threats and help utilities maintain uptime and compliance.
Oil and Gas
In upstream, midstream, and downstream operations, NGFWs secure process control networks and SCADA systems to defend against threats by inspecting traffic between remote sites, field devices, and control centres. The rugged design ensures reliable operation in harsh environments, while advanced filtering capabilities block malicious traffic without disrupting production.
Transportation and Rail Networks
Siemens NGFWs are applied to safeguard signalling systems, traffic management platforms, and communication infrastructure, enabling secure remote monitoring of critical assets, protecting against unauthorised access and cyber disruptions that could impact safety or service continuity.
Water and Wastewater Utilities
Water utilities rely on NGFWs to protect pump stations, treatment facilities, and distributed field assets. Siemens NGFWs help secure OT environments by isolating network segments, detecting anomalies in industrial protocols, and allowing controlled access for remote operators.
Industrial Next Generation Firewall
System complexity is rising and cybersecurity threats are increasing. Industrial Next Generation Firewall is a perimeter protection solution that reduces exposure to vulnerabilities in line with security requirements for industrial automation.
