Cybersecurity for industrial systems and critical infrastructure

Leviotec supports energy, transport, and industrial organizations with OT cybersecurity audits, industrial penetration testing, and dedicated expertise, in France and internationally

[ Our specialty ]

Industrial cybersecurity is a discipline of its own

Protecting a plant, a substation, or a dam cannot be done with conventional IT security methods. Industrial systems control physical equipment: securing them requires specific skills, methods, and precautions.

Systems that control the physical world

PLCs, control systems, SCADA supervision. An attack can have physical and human consequences, not just data loss.

Strict availability constraints

A plant or a substation doesn't stop for an update. Every intervention must preserve operational continuity.

Equipment and protocols specific to industry

PLCs, sensors, and industrial protocols follow their own rules. Conventional IT security tools fall short.

Dedicated frameworks

Industrial security follows its own frameworks, such as IEC 62443 or the NIS2 directive, which must be applied in the field.

How an engagement unfolds

[ Step 01 ]

Scoping

Understanding your facilities, operational constraints, and objectives. Precise definition of the scope, rules of engagement, and points of contact.

[ Step 02 ]

Diagnostic and intervention

The mission is carried out on site or remotely: audit, penetration test, or advisory support, using methods designed not to disrupt production.

[ Step 03 ]

Reporting

A report ranked by risk level, with a prioritized action plan. Findings are tailored to each audience: technical teams and management.

[ Step 04 ]

Follow-up

Support in implementing the action plan, with ongoing follow-up on measures, at the pace of your projects.
