Solution

Protect your operations.
Without disruption.

Fortaress is an all-in-one solution designed to implement OT cybersecurity best practices easily and quickly, without compromising operational continuity.

Positioned between IT and OT networks, Fortaress isolates the critical perimeter using a next-generation industrial firewall (NGFW OT) capable of analyzing industrial protocols, providing an intelligent and tailored security barrier.

Fortaress enhance OT security through:

$

Non-intrusive security mechanisms

such as OT virtual patching, OT IPS, and OT application control.

$

Its integrated SIEM and 24/7 MDR service

ensuring continuous monitoring, rapid threat detection, and proactive response.

Together, these features form a comprehensive, integrated solution that can be deployed without disrupting industrial operations.

What does it actually do?

1. Isolates OT network

Fortaress is strategically deployed between OT and IT networks to reinforce security where traditional firewalls fall short. Even if a primary firewall is already in place, adding an OT-specific NGFW provides an essential layer of protection.

With native support for protocols like Modbus, DNP3, OPC-UA, and BACnet, Fortaress deeply analyzes industrial communications. By strictly filtering incoming and outgoing traffic, it limits access to only what’s necessary — acting as an intelligent gatekeeper, perfectly suited to OT environments.

2. Optimizes OT segmentation

Lack of visibility into OT assets is a major barrier to effective segmentation. Industrial environments often include outdated or undocumented equipment, making it difficult to define clear security zones. In SMBs, the priority given to process stability makes any modification risky and complex. As a result, companies often avoid touching existing OT assets, even if it means accepting a certain level of risk.

Fortaress addresses this challenge with its OT asset discovery feature: it continuously scans the network, identifies each device (type, manufacturer, firmware, etc.), and maintains a dynamic inventory. When deployed in transparent mode (requiring no reconfiguration), Fortaress operates in read-only mode, allowing it to observe legitimate traffic flows without interference and detect mispositioned assets at the IT/OT boundary. This approach delivers clearer visibility into what truly belongs in the OT network.

3. Enhance OT assets security

Protecting industrial environments without disrupting operations is a critical challenge. Fortaress integrates three key features that deliver deep protection with zero impact:

  • OT virtual patching safeguards vulnerable devices even when updates can’t be applied.
  • OT IPS defends against real-time attacks targeting both IP and industrial protocols.
  • OT application control restricts execution to authorized software only.

These mechanisms significantly strengthen security while preserving the stability and availability of critical systems.

4. Monitors OT traffic

Monitoring OT traffic is essential for detecting threats early. Fortaress’s integrated SIEM collects and correlates event logs in real time to identify suspicious activity.

Combined with its 24/7 MDR service, Fortaress delivers continuous monitoring, proactive analysis, and rapid incident response, all without disrupting critical operations. This enhanced visibility improves threat detection across protocols often overlooked by traditional tools.

No changes made to existing equipment.

01

Controlled deployment

Traffic flows are analyzed passively, and protection mechanisms are activated gradually, once critical access and communications have been identified and validated with the client.

02

No interference

Virtual patching, OT IPS, and application control are applied at the network level, with no direct interaction with PLCs or critical equipment.

03

No modifications

No updates are forced on systems, software, or firmware. No changes are made to IT or OT network configurations.

Reduced attack surface and blast radius.

Fortaress reduces the attack surface through:
$
Optimized network segmentation
$
Intelligent filtering of OT communications
$
Strict access and application control
This limits potential entry points and blocks unauthorized connections. In the event of an intrusion, Fortaress also reduces the blast radius thanks to effective segmentation, OT virtual patching for outdated devices, real-time OT IPS, and continuous monitoring through an integrated OT SIEM.

Result

Threats are contained before they spread, ensuring the resilience of industrial operations without compromising availability.
