Practice
Industrial & OT Technology
Keep the plant running, and keep it defensible.
Overview
Oil and gas, power, water and manufacturing operators run estates that were designed for uptime, not for hostile networks. We work at the seam where operational technology meets corporate IT, the place where most incidents, and most avoidable downtime, actually begin.
Our engineers speak both languages. We can read a P&ID and a firewall rule set, and we translate between the control room and the board so that security work does not stall production.
Capabilities
- OT/IT convergence architecture
- Purdue-model zoning, DMZ design, segmentation and secure remote access for plant networks.
- ICS/SCADA security assessment
- Passive asset discovery, vulnerability triage and risk ranking against IEC 62443 and NIST SP 800-82.
- Industrial identity and access
- Machine and human identity, certificate lifecycle, least-privilege access for controls engineers and vendors.
- Edge data and telemetry
- Historian integration, edge gateways, MQTT/OPC UA pipelines and site-to-cloud synchronisation.
- Incident readiness
- OT-specific playbooks, tabletop exercises and recovery planning that account for safety systems.
- Vendor and contractor governance
- Third-party access control, change management and supply-chain assurance for plant equipment.
