Key Features
Designed to secure your processes, without ever disrupting them.
Each feature is designed to enhance OT cybersecurity without disrupting operational processes, while accounting for industrial realities: ICS, legacy equipment, continuous availability, lack of patching, and more.
OT SECURITY
Industrial NGFW for OT
Fortaress’s Next-Generation Firewall (NGFW OT) is specifically designed for industrial environments. Unlike traditional IT firewalls, it understands and interprets industrial protocols such as Modbus, DNP3, OPC-UA, and BACnet. This allows it to accurately filter legitimate communications from intrusion attempts or malicious manipulation. With deep packet inspection (DPI), Fortaress blocks suspicious commands without disrupting the normal operation of industrial equipment. It can also detect abnormal behavior, such as attempts to shut down a PLC or unauthorized changes in a SCADA configuration. This intelligent protection acts as an active shield against network attacks targeting your production systems — and serves as a key pillar in your OT defense strategy.
OT network segmentation
Fortaress enables effective segmentation of your OT network by isolating critical infrastructure from the rest of your IT environment. This segmentation significantly reduces the risk of a cyberattack spreading, as it prevents malicious actors from accessing the entire network through a single entry point. With optimized OT segmentation, you can isolate PLCs, HMIs, and all OT devices from other systems, limiting unauthorized or unnecessary machine-to-machine communications while preserving the availability of essential services. This approach aligns with IEC 62443 best practices.
OT Intrusion Prevention System (IPS)
The OT-specific Intrusion Prevention System (IPS OT) built into Fortaress continuously monitors all inbound and outbound traffic on the OT network. It can automatically detect and block attempts to exploit known vulnerabilities, network attacks such as scans and command injections, as well as abnormal behaviors associated with advanced persistent threats (APT). Unlike traditional IPS solutions, Fortaress’s IPS is trained on OT-specific signatures and behavioral patterns. This allows it to protect your systems even when they rely on legacy devices or proprietary protocols. The system operates without disrupting operations, providing a critical layer of defense to safeguard your production lines and industrial processes.
OT CONTROL
OT network access control
With Fortaress, you can enforce strict access control rules to limit what can connect to the OT network. This feature is designed to grant access only to devices and applications that are essential to the continuous operation of your industrial processes. It helps prevent malicious, unauthorized, or accidental connections—one of the leading causes of infections in industrial networks. Combined with logging capabilities, it also ensures complete traceability of actions performed on the network. This is a powerful way to strengthen security while meeting compliance requirements such as NERC CIP and IEC 62443.
OT application control
This feature identifies, in real time, active industrial applications—such as HMI/SCADA software, configuration tools, or PLC communication utilities—and allows you to block those that are unauthorized, outdated, or potentially dangerous. It helps reduce risks associated with unverified or pirated tools, and prevents unsupervised configuration changes or firmware downloads. It can also block the use of remote desktop or file-sharing applications that have no place in an industrial environment. With this level of control, only authorized communications essential to the production process are allowed, ensuring a strong security posture without impacting operational performance.
Virtual patching for OT assets
In many OT environments, applying software patches to PLCs, SCADA servers, HMIs or other industrial devices is risky—or simply not possible. Some systems can’t be shut down; others no longer support updates. Fortaress offers a powerful alternative with virtual patching. This technology actively blocks attempts to exploit known vulnerabilities, even when the targeted device remains technically unpatched. With a continuously updated threat signature database, Fortaress intercepts and neutralizes attacks before they can reach critical systems. This enables industrial operators to secure their operations without interrupting production, delivering protection comparable to software updates. Virtual patching is an essential solution for safeguarding legacy infrastructure and ensuring ongoing resilience in environments where every minute of uptime matters.
OT VISIBILITY
OT Asset Identification
Strong cybersecurity begins with a clear understanding of what is connected to the network. Fortaress provides complete visibility into all OT assets, including programmable logic controllers (PLCs), human-machine interfaces (HMIs), sensors, cameras, gateways, SCADA servers, and more. It automatically identifies connected devices, their manufacturer, operating system, role, and in some cases even their firmware version. This passive identification is performed without disrupting traffic or ongoing operations.
By centralizing this data into a dynamic inventory, Fortaress offers a clearer view of the network, helps identify outdated or vulnerable assets, and supports the planning of targeted protection measures. This forms a key foundation for effective segmentation, risk management, and informed decision-making in industrial cybersecurity.
Unknown or unapproved devices identification
The OT asset identification feature offers an additional layer of protection by detecting the appearance of any new device that has not been previously authorized. Whether it is a laptop connected to an Ethernet port, a temporary maintenance tool, or an intrusion attempt, every new connection point is evaluated in real time. When an unknown device is detected, an alert is immediately generated. If desired, this alert can trigger automated responses such as blocking the connection or isolating the device. This helps prevent unauthorized access, insider threats, or human errors that could compromise operational security. This feature is especially valuable in industrial environments where multiple external contractors or technicians may have access to the site. It acts as an invisible yet constantly vigilant surveillance layer.
OT Traffic Log Aggregation
One of the major challenges in industrial cybersecurity is the ability to track, understand, and correlate events occurring in the OT environment. Fortaress automatically collects logs generated by inbound and outbound OT network traffic and centralizes them within a unified platform. These logs may include security alerts or unusual connection attempts. By normalizing this data and making it accessible from a single location, Fortaress simplifies incident analysis, enables the detection of suspicious behavior, and supports full traceability of actions across the OT network. This enhanced visibility not only speeds up threat response but also helps meet regulatory requirements related to log management. Log aggregation is a foundational element of any effective detection and investigation strategy in industrial environments.
THREAT DETECTION
Monitoring of OT Traffic (inbound and outbound)
Our SOC acts as a strategic observation point between IT and OT networks. It closely monitors all inbound and outbound data flows within the industrial network. This bidirectional visibility enables the detection of suspicious connections, unauthorized file transfers, abnormal access attempts, or outbound communications that have no place in an OT environment. By analyzing both packet content and network behavior, Fortaress can identify early signs of an attack or data exfiltration. This monitoring also makes it possible to document and audit communications to meet compliance or investigation requirements. With this capability, organizations gain precise control over what enters and leaves their critical zones, effectively reducing the attack surface.
Integrated OT SIEM
Fortaress includes a correlation engine based on SIEM (Security Information and Event Management), tailored to the realities of OT environments. It centralizes, correlates, and analyzes all security events from the industrial network in real time, including suspicious connections, anomalies in data flows, network configuration changes, and abnormal behavior. This system powers our managed threat detection service, where analysts continuously monitor alerts, validate incidents, and recommend corrective actions. The combination of advanced technology and human expertise enables the rapid detection of any abnormal activity. The integrated OT SIEM module adds a layer of continuous cyber monitoring designed to act as a strong line of defense in industrial cybersecurity.
Incident Response
When a cybersecurity incident hits an industrial environment, every second counts. Fortaress provides an incident response capability specifically designed for OT networks. In the event of abnormal activity, an intrusion, or an active threat, the system triggers real-time alerts and enables rapid intervention by our response and remediation experts. This response may include log analysis, identification of the attack source, isolation of compromised assets, or the on-the-fly application of blocking rules. With this functionality, organizations can limit the impact on critical operations, reduce downtime, and quickly regain control, even in the face of sophisticated threats.
