Cybersecurity for Industry and Energy

Security Testing for IT and OT Environments

We assess the security of IT and OT environments, industrial networks, production technologies, and ICS and SCADA systems. OT, ICS, and SCADA penetration testing is adapted to operational constraints so that it does not endanger production continuity or controlled physical processes.

Why Test Cybersecurity in Industry and Energy?

Industrial and energy organizations operate systems that control manufacturing, energy distribution, and other physical processes. A cyberattack may therefore cause more than a data breach. It can stop production, disrupt essential services, damage equipment, or endanger people.

The connection of IT and OT environments, legacy components, insecure industrial protocols, and remote service access all increase risk. A weakness in the corporate network or a supplier’s system can provide an attacker with a path to industrial control technologies.

Security testing helps uncover potential attack paths and verify the effectiveness of implemented controls. We tailor the scope to the sensitivity of the environment and the organization’s operational constraints.

Protection of Operational Continuity

We identify weaknesses that could interrupt production, shut down technologies, or disrupt energy supplies.

More Secure IT and OT Integration

We assess segmentation, communication flows, and access rules between corporate and industrial networks.

Control of Remote Access

We assess VPNs, service accounts, supplier access, and other methods used to remotely manage industrial systems.

Better Visibility into Operational Risks

We evaluate findings according to their technical severity and potential impact on production, supplies, and physical processes.

Who Is Security Testing For?

We tailor testing to the type of operation, technologies used, criticality of controlled processes, and requirements for availability and safety.

Manufacturing Companies

We assess production networks, automated lines, control systems, industrial equipment, and connections between production environments and corporate IT.

Energy Companies

We test systems used to generate, transmit, and distribute electricity, gas, heat, and other energy services.

Critical Infrastructure Operators

We assess the security of technologies on which essential services and critical operational processes depend.

Industrial Technology Suppliers

We test control solutions, service access, integration platforms, and systems through which suppliers manage their customers’ technologies.

What Do We Test in Industrial and Energy Organizations?

Security Testing and Resilience Requirements

Industrial and energy organizations must protect both information systems and the technologies controlling physical processes. Regulatory and security frameworks therefore emphasize risk management, operational continuity, supply chain protection, and the security of industrial control systems.

Security testing provides technical evidence for identifying weaknesses and verifying the effectiveness of implemented controls. However, it does not replace legal assessment or a comprehensive compliance audit. We explain when to choose an audit, a penetration test, or both approaches in our article Security Audit vs. Penetration Testing.

Relevant Regulatory and Security Frameworks

NIS2

NIS2 covers the energy sector and selected manufacturing industries. It emphasizes cyber risk management, supply chain protection, operational continuity, and preparedness for security incidents.

IEC 62443

The IEC 62443 series focuses on the security of industrial automation and control systems throughout their lifecycle. It includes requirements for operators, system integrators, and component manufacturers. OT, ICS, and SCADA testing can help verify the effectiveness of implemented technical controls.

CER

The Critical Entities Resilience Directive focuses on the ability of organizations to prevent disruption, withstand incidents, and restore essential services. Energy and other critical infrastructure sectors are among the areas covered.

Cyber Resilience Act

Manufacturers of connected devices, software, and other products with digital elements may be subject to the Cyber Resilience Act. Security testing helps identify product vulnerabilities and verify the effectiveness of protection throughout the product lifecycle.

How Can an Attack Affect Industrial Operations?

Attackers can combine weaknesses in IT systems, OT networks, control technologies, and remote access. The consequences may directly affect physical operations.

Production or Supply Disruption

An attack against control systems, servers, or network infrastructure can interrupt production and disrupt energy or other essential services.

Movement from IT to OT Networks

Insufficient segmentation can allow an attacker to move from the corporate environment to systems controlling physical processes.

Unauthorized Process Changes

Access to a PLC, HMI, or SCADA system can allow an attacker to change production parameters, equipment behavior, or industrial processes.

Compromise Through a Supplier

A compromised service account, remote connection, or supplier device can provide a path into industrial infrastructure.

Concealment of Malicious Activity

Insufficient monitoring can allow an attacker to remain in the environment for an extended period without being detected by the security team.

The Citadelo team holds dozens of certifications, including ISA/IEC 62443, OSCP, OSEP, OSCE³, CRTO, and CISSP, relevant to industrial and OT system security.

Frequently Asked Questions

Answers to common questions about security testing for manufacturing companies, energy organizations, and industrial infrastructure.

Yes. We adapt the scope, schedule, and safety rules to the criticality of the controlled processes. Higher-risk scenarios are performed only by agreement, during a planned shutdown, or in a separate testing environment.

We design testing to minimize the risk of outages or interference with physical processes. Potentially dangerous actions are not performed in active production environments without explicit approval.

Yes. We assess corporate IT infrastructure, industrial networks, control systems, and the connections between them. This allows us to uncover potential attack paths from the corporate network into the OT environment.

Yes. We adapt the testing approach to the age, sensitivity, and availability of the system. For devices that cannot be safely tested actively, we use configuration reviews, communication analysis, or testing in an isolated environment.

Yes. We test VPNs, remote administration, service accounts, and access granted to external suppliers. We assess whether compromised access could provide a path into the industrial network or control systems.

Yes. We assess PLCs, HMIs, SCADA and DCS systems, engineering workstations, industrial protocols, access permissions, and opportunities to modify configurations or controlled processes without authorization.

Yes. The results can provide technical evidence for cyber risk management and verification of security controls under NIS2 or IEC 62443. Testing does not, however, replace legal assessment, certification, or a comprehensive compliance audit.

We begin by mapping the IT and OT architecture, critical processes, communication flows, remote access, and operational constraints. Based on the identified risks, we define the systems to be tested, permitted scenarios, and a safe testing approach.

You will receive a technical report describing the vulnerabilities, supporting evidence, risk ratings, and specific remediation recommendations. We also evaluate findings according to their potential impact on production, supplies, and physical processes.

Yes, a retest can be included in the agreed project scope. Once remediation is complete, we verify whether the vulnerabilities have been properly resolved and whether the changes introduced any additional security risks.
