Protect the plant without stopping it

ICS, SCADA and PLC protection with IEC 62443-aligned segmentation - without disrupting the plant floor.

OT Security Services

In an office environment, the worst case is data loss. On a plant floor, it's a stopped production line, a damaged asset, or a safety incident. That difference is why operational technology security can't simply be IT security applied to industrial equipment, OT prioritises availability and physical safety over data confidentiality, runs on equipment with 15- to 30-year lifecycles, and often cannot be patched or rebooted on an IT team's schedule.

Vinca Cyber's OT security practice secures industrial environments on their own terms, bringing the same 360° Cyber Resilience approach we've applied since 2017 to manufacturing and critical infrastructure clients, without introducing controls that disrupt the processes they're meant to protect.

OT

What is OT security?

Protects ICS/SCADA, PLCs and related systems that control physical processes — where downtime means safety or production risk.

IT/OT convergence removed the old air gap; attackers often reach OT through the IT network.

Segmentation and OT-aware controls close that path without treating the plant floor like a data centre.

What is OT security?

Our OT security services

Passive discovery, segmentation and OT-aware monitoring designed around plant-floor constraints.

OT Asset Discovery & Inventory

Passive identification of every device on the industrial network, including legacy equipment nobody has documentation for.

Network Segmentation

Zone and conduit design aligned to IEC 62443 and the Purdue Model, limiting how far an IT-side compromise can travel.

OT-Specific Monitoring

Behavioural detection tuned to industrial protocols such as Modbus, DNP3 and OPC UA, where standard IT tooling is effectively blind.

Risk-Based Patch & Compensating Controls

Practical remediation for systems that genuinely cannot be patched or taken offline.

Secure Remote Access

Controlled vendor and engineer access to PLCs and HMIs, replacing shared credentials and always-on VPN tunnels.

Compliance Alignment

Mapping controls to IEC 62443 and NIST SP 800-82 for audit and regulatory review.

Why OT security is different

OT prioritises availability and safety; a routine IT reboot can halt production.

Active scanning and aggressive patching can crash legacy PLCs — passive discovery and compensating controls fit better.

Decade-long equipment lifecycles mean unsupported OS is normal; design around that, don't ignore it.
