Sector — SME & Industry

Infrastructure worthy of your industrial ambition

SMEs in Drôme, Ardèche or Auvergne-Rhône-Alpes: DYB modernises your IT system so it keeps up with your growth.

Your challenges

The IT challenges of industrial SMEs

Unsegmented OT/IT systems

Production machines and IT on the same network — a critical vulnerability often ignored.

Ageing infrastructure

End-of-life servers, obsolete Windows versions, no monitoring — failure risk is high.

ERP dependency

A poorly maintained or poorly secured ERP can paralyse all production in case of incident.

Lack of IT resources

No internal IT department, or a single person managing everything — responsiveness suffers.

What we do

Industry-tailored solutions

Industrial managed services

Outsourced IT department with OT/IT expertise: monitoring, maintenance, incident handling.

OT/IT cybersecurity

Network segmentation, hardening of machine access, industrial environment audit.

Business applications

ERP, CMMS, custom traceability tools — tailored to your production processes.

IT modernisation

Server replacement, virtualisation, cloud migration — without production interruption.

The context from the inside

Your workshop in 2026 — we have seen many

The average factory network still mixes Siemens or Schneider PLCs on rock-solid Windows XP/7, Wonderware or PcVue supervision connected to the same VLAN as office IT, in-house CMMS on a Windows 2008 R2 server, locally hosted SAGE or CEGID ERP, and several operator PCs shared on a single account with the password stuck on the screen. When ransomware hits, it encrypts accounting files, production recipes and process parameters indiscriminately. Daily downtime cost runs from €5,000 to €50,000.

Since October 2024, NIS2 classifies most industrial "manufacturing" SMEs as important entities: requirement for a documented cyber arrangement, incident notification within 24 hours, financial sanctions in case of breach. For automotive, aerospace or defence subcontractors, clients now require audit evidence (TISAX, ISO 27001, specific attestations). Industrial cyber is no longer something to do "when we have time".

Our method for industry

Full OT/IT mapping

Inventory of PLCs, supervisions, operator workstations, servers, inter-network flows. Identification of lateral attack paths.

VLAN segmentation industry ↔ office

Industrial firewall, flow whitelists, OT-specific monitoring. Office ransomware no longer reaches production.

Immutable backups and tested DRP

3-2-1 backup with immutable off-site copy. Restore tested every quarter on full scenarios, including production halt and restart.

Production continuity plan (DRP)

PLC isolation procedure, documented degraded mode, up-to-date emergency contacts. When things break, the team knows what to do and in what order.

Client case — Lyrelec, industry

"DYB rebuilt our entire system infrastructure. Servers no longer crash on Friday evening. For the first time in 5 years."

Marc Chambon, CEO of Lyrelec, inherited an infrastructure built by accretion: mismatched servers, incomplete backups, no visibility into the estate. Friday evening outages had become a routine the whole team had learned to dread. DYB rebuilt the infra on Proxmox virtualisation, segmented networks, set up immutable backups and 24/7 monitoring. Fridays have become quiet again.
