Industrial Cybersecurity

In OT, stopping production is not an option

An industrial environment is not audited like an office one. PLCs, SCADA and control systems do not tolerate aggressive scanning, many have been in service for decades with no way to patch them, and the priority is not confidentiality: it is availability and human safety. Applying IT methodology to a plant is the fastest way to cause the very incident you were trying to prevent.

What regulation requires it

• NIS2: energy, water, transport, manufacturing, food and healthcare are fully in scope, with personal liability for the management body.
• IEC 62443: the international reference framework for security in industrial automation and control systems.
• Critical infrastructure legislation, if you are a designated operator.

What we do

Asset inventory and visibility. You cannot protect what you do not know you have. Passive discovery of OT assets without interfering with operations.

Architecture and segmentation audit. Review of IT/OT convergence, zones and conduits following IEC 62443, industrial DMZ, and remote access by vendors and third parties.

Adapted vulnerability assessment. Non-intrusive techniques on production systems, with active testing only in lab environments or agreed maintenance windows.

A realistic improvement plan. With compensating controls for everything that cannot be patched, which in OT is almost everything.

What you get

• OT asset inventory with criticality to the process.
• Zone and conduit diagram with segmentation gaps flagged.
• Executive and technical reports, with risk expressed as impact on production.
• Phased remediation plan, compatible with your scheduled shutdowns.
• Conformity matrix against IEC 62443 and NIS2.

Frequently asked questions

Are you going to stop my plant? No. The discovery phase is passive. Any active testing is agreed in writing, with a window and a rollback plan.

Do you have real industrial experience? The team holds the Spanish Industrial Cybersecurity Centre (CCI) Black Level Professional certification, an OT industrial cybersecurity certificate and specific university training in the field.

Our systems are old and cannot be updated. That is normal in OT. This is why the plan relies on segmentation, access control and monitoring rather than patching.
