Hirschmann Firewall – Securing Industrial Networks with Advanced Protection
Cybersecurity in industrial applications is not an optional component of today’s connected world; it is a necessity. With factories, plants, and operational environments digitalizing and capitalizing on the IIoT, the threats of cyberattacks on operational technology (OT) networks are increasing exponentially. As a leader in industrial networking, Hirschmann minimizes these concerns by providing next-level solutions. All of the firm’s solutions are based on the Hirschmann Firewall – the industrial-grade firewall appliance that secures critical infrastructure, promotes OT-IT convergence, works in unison with industrial network switches, and with industrial cyber solutions to provide a complete defense-in-depth.
Hirschmann Firewall device
The belden Hirschmann Firewall is a next-generation firewall appliance built specifically for industrial networks security, not to be confused with other IT firewall solutions. Informational Technology(IT) firewalls cannot be relied upon to work in industrial environments characterized by harsh conditions, supporting industrial protocols, and being stripe-able. The functions of a Hirschmann Firewall include packet filtering, access control, VPN connectivity, and deep packet inspection (DPI).
Integrating Industrial Network Switches with Hirschmann Firewall
In an industrial environment, an industrial network switch connects multiple communication devices such as controllers, sensors, and HMIs for easy and fast communication. These industrial switches are designed to be ultra-durable with ultra-low latency and ultra-high reliability.
Switch and Firewall Cooperation for Network Segmentation
In the case of the Switches and Hirschmann Firewall integration, as the switches handle communication between devices, the Firewall enforces security policies on the borders of the protected zones. This method, prevents the malware from penetrating the critical systems, and allows for certified transaction data flow.
Direct Integration of Switches with Firewalls for Enhanced Industrial Communication
Hirschmann industrial network switches can be incorporated with Hirschmann’s own line of firewall devices for industrial-grade communication with the devices and ease of configuration due to centralized control through unified cybersecurity policies. This makes the devices fundamental for an industrial communication system.
Industrial Cyber Security Solutions
Current approaches to industrial cyber security begin and do not end with perimeter defense. Firewalls and Segmentation with Intrusion Preventation and constant surveillance/combing of the networks should be integrated.
- Intrusion Prevention: response to a attempts and malicious actions.
- Network Segmentation: a barrier that protects critical assets from the general network.
- Monitoring & Threat Detection: Figure out and deal with unexplained anomalies.

Key Features of the Hirschmann Firewall Device

Deep Packet Inspection (DPI)
Enables the ability to inspect and filter the monitored industrial protocols to suppress the execution of unauthorized industrial commands or the transmission of packets which are harmful in nature.

VPN and Secure Remote Access
Enables the ability to establish secure remote connections to the monitored target systems and to partners of the maintenance team while ensuring the target systems are not exposed.

High Availability and Redundanc
Offers the ability to maintain organized operations with redundant configurations and critical fail-over support as well as seamless operation of the fail-over support to maintain uninterrupted industrial functions.

Integration with Industrial Network Switches
Attains unified command by interlocking the traffic control between multiple switches and the firewall policies to increase control.
