The costs CyberSecurity from industrial laboratories

In recent years, cyber threats targeting industrial infrastructures have become much more sophisticated, and organizations are forced to invest more in protecting their OT (Operational Technology) systems. However, in addition to the obvious security costs – software solutions, equipment, audits – there are also a number of hidden costs which is especially evident in industrial laboratories, where prototypes, experimental processes and advanced testing are the core of innovation.
These labs are not only places where technologies are tested, but also environments where vulnerabilities can appear unnoticed and attackers can gain access to highly sensitive information.

Current context: why industrial laboratories are attractive targets

Industrial laboratories are often perceived as isolated or poorly connected to the main networks, creating a false impression of security. However, in reality, these environments are becoming increasingly interconnected, especially with the accelerated adoption of digitalization, IoT industrial and modern operational analysis tools.
According to experts in the field, including Rich Kellen, CIO of IFF, laboratories are often ignored in security strategies, even though they represent one of the most critical components for companies' competitiveness.

Hidden costs in OT labs

Hidden costs arise because OT labs combine legacy infrastructure with modern technologies. The result is a complex ecosystem that is difficult to secure, where breaches can have significant financial and operational consequences. Below are the main categories of hidden costs identified in these environments:

1. Costs related to lack of visibility over assets

One of the biggest risks in industrial labs is the lack of clear monitoring of equipment, connections, and data flows. Many organizations don’t know exactly how many devices are connected to the network or what protocols are being used in the lab. This lack of visibility leads to:

hidden assets that are not monitored;
systems that are not updated or properly secured;
exposure to breaches that can remain undetected for months.

When you lack visibility, you invest in the wrong or insufficient solutions, generating high costs in the long term, including potential incidents that could have been prevented.

2. Unplanned integration of new equipment

Laboratories are dynamic places: new technologies, equipment or sensors are frequently tested. Integrating them without a standardized procedure creates technological gaps that are difficult to control.
A simple device IoT introduced for testing can open a door to the network, and the costs arise from:

the need to reconfigure the network after installation;
additional expenses for infrastructure auditing;
further investments in microsegmentation, firewalls or IDS/IPS systems adapted to hybrid environments.

In essence, the lack of a clear integration process quickly turns into an unexpected consumption of resources.

3. Vulnerabilities in legacy systems

Many industrial labs have equipment that is 10-20 years old. These devices were designed for performance, not security, and may run operating systems that no longer receive updates.
Hidden costs arise from:

the need to isolate these systems through expensive hardware solutions;
high risk of exploitation, which can generate production interruptions;
the need for specialized personnel for maintenance and monitoring.

Even if the equipment itself works flawlessly, the lack of security support turns it into a major attack vector.

4. Excessive dependence on manual procedures

OT labs often rely on manual labor: operators connecting systems, reconfiguring equipment, or transferring data between workstations. This reliance creates hidden costs because:

manual activities increase the risk of human errors;
employees require additional and repeated training;
further automation becomes more expensive due to the complexity of existing processes.

Often, vulnerabilities do not come from the tools themselves, but from how they are used by staff.

5. Lack of an internal security culture for laboratory teams

Technical teams in labs are typically focused on innovation, testing, and operational efficiency, not security. This creates hidden costs such as:

the need for specialized training programs;
late implementation of security controls;
dependence on central IT teams, which generates delays in critical processes.

A team that is not prepared for cyber risks will inevitably create breaches, even unintentionally.

6. Uncontrolled interconnection between IT and OT networks

Many labs operate in parallel with the corporate IT infrastructure, and the connections between them are becoming increasingly tight. This interconnection brings efficiency, but also major vulnerabilities:

an attack in IT can quickly reach OT;
lab projects can be accidentally exposed on the network;
Sensitive data can be compromised through unsecured channels.

Costs arise from the need for additional segmentation, Zero Trust solutions, and post-incident investigations.

7. Compliance and audit costs difficult to predict

Regulatory requirements, such as NIS2 directives, require organizations to demonstrate control over their OT infrastructure. Industrial labs, being complex and poorly documented, can generate significant hidden costs in the compliance process.
These costs include:

manual collection of information about assets;
retroactive implementation of security controls;
high costs with external audits.

Without a clear strategy, organizations risk sanctions and delays in operations.

Strategies for reducing hidden costs

Although industrial laboratories are complex, hidden costs can be significantly reduced through a structured approach. Below are some effective directions:

1. Implementing complete visibility over assets

The first step in reducing costs is to fully map your infrastructure. Modern tools can passively scan OT networks to identify each device. Visibility allows:

vulnerability detection;
correct investment planning;
Disposal of unused or hazardous equipment.

This process dramatically reduces the costs associated with unnoticed attacks or redundant investments.

2. Creating a standardized integration process for new equipment

A well-defined process for introducing equipment into the laboratory eliminates many of the gaps generated by spontaneous tests. Standardization should include:

risk assessment;
security scan before connection;
inventory documentation and updating.

This operational discipline reduces risk and related costs.

3. Intelligent isolation of legacy systems

Instead of a full modernization, which can be costly, many organizations choose to isolate legacy systems through micro-segmentation, industrial gateways, or dedicated VPNs. This approach:

protects systems without interrupting processes;
decreases the risk of attack;
reduces the need for complex maintenance.

Isolation is a cost-effective and effective long-term strategy.

4. Automate manual processes

Automation reduces both operational risks and the costs associated with human error. Modern tools allow for the automation of logs, configurations, and even some tests. The result:

lower resource consumption;
fewer vulnerabilities;
increased productivity.

Every manual activity eliminated represents a direct reduction in hidden costs.

5. Forming a security culture in industrial laboratories

Employees need to be aware that security is not just the responsibility of IT. Introducing a security-oriented culture includes:

regular training;
incident simulations;
accountability programs.

Educating teams reduces involuntary breaches and their associated costs.

6. Adopting Zero Trust architecture

The Zero Trust model is essential in modern OT environments. It assumes that no connection is considered secure by default. Benefits include:

granular access control;
limiting the spread of an attack;
less remediation costs.

Zero Trust is becoming a requirement for any digitalized industrial laboratory.

Conclusion

Industrial labs are a critical space for innovation, but also a breeding ground for hard-to-detect cyber vulnerabilities. The hidden costs of heterogeneous infrastructure, lack of visibility, reliance on legacy systems, and human error can far exceed an organization’s initial budgets. A structured and proactive approach—based on visibility, standardization, isolation, automation, and education—is essential to protecting these environments.
Organizations that invest intelligently in securing industrial laboratories not only reduce hidden costs, but truly protect their technological future and competitiveness.
