Industrial communications and OT cybersecurity

We design industrial networks and OT/IT protection layers for facilities where connectivity, availability and access control directly affect operations.

Industrial communications are not just about cabling or switching. We define architecture, segmentation, equipment and security controls so the system remains operational and resilient.

What we do

We assess needs from the physical layer to integration with corporate IT networks, including TCP/IP design, cabling, fiber, wireless access, industrial equipment and security controls.

Alventia already positions this line around industrial cybersecurity, secure access, segmentation and regulatory alignment in OT environments.

Core capabilities

  • Industrial network architecture, topology and segmentation by zones and conduits.
  • Design of cabling, fiber, industrial switching and routing.
  • Integration of firewalls, NAC, LDAP, 802.1x, IDS/IPS and monitoring.
  • Controlled convergence between OT and IT with security and operations criteria.
  • Support for measures aligned with IEC 62443 and applicable regulations.

When it matters most

  • When a SCADA or control system grows beyond an improvised network model.
  • When multiple sites or remote access need secure connectivity.
  • When continuous operation must coexist with compliance requirements.
  • When the client needs visibility into OT assets, access and exposure surface.

Expected outcome

  • A more stable and maintainable network.
  • Lower operational risk caused by unmanaged access or weak architecture.
  • Clearer conditions to integrate new systems and vendors.
  • A stronger base for digitalization without multiplying OT vulnerabilities.

Frequently asked questions

Is OT cybersecurity just about adding a firewall?

No. A firewall is only one control. The real value comes from the full architecture: segmentation, access control, inventory, rules, visibility and operational coordination.

Do you work on new and existing networks?

Both. We can design from scratch or assess existing networks to stabilize them, segment them and adapt them to new operating or compliance requirements.

Can this be integrated with existing control systems?

Yes. This capability is designed to coexist with SCADA, PLC, BMS and other OT layers without disrupting plant operation.
