Topsec Industrial Control System Firewall

Leveraging its extensive expertise in the industrial control field, Topsec has developed a whitelist-based "four-dimensional" in-depth protection technology for industrial command-level security. This technology performs advanced filtering and protection by validating the "integrity," "function codes," "address ranges," and "process parameter ranges" of industrial control protocols. It effectively detects suspicious commands and malicious data, ensuring the secure operation of industrial control networks and devices through access control, behavioral analysis, and data verification.

Equipped with an ai-powered protocol identification engine, the system supports the recognition of 76+ industrial protocols. It employs multiple identification techniques, including: single-packet signature recognition、statistical feature recognition、multi-packet correlation analysis、deep parsing-based identification.This comprehensive approach meets the diverse application and protocol management needs of industrial enterprises.

The system integrates a dedicated industrial attack signature database and malware detection engine, covering over 80% of known industrial control threats, including:Intrusions targeting scada, plc, and dcs systems、malware infections、buffer overflow attacks、denial-of-Service (ddoS) attacks.By accurately identifying and blocking these threats, it prevents security risks from spreading and ensures stable industrial control system operations.

To address the evolving demands of modern industrial networks, topsec enhances standard networking functions with industrial-specific features, such as: virtual private networks (vpns)、ipv6 support、virtual wire switching、dual-system hot backup、link aggregation、load balancing、traffic management. These capabilities enable seamless integration into complex industrial environments, reducing additional infrastructure investments and supporting the growth of industrial internet of things applications.
