Oil & Gas
Engineering for assets that operate for decades in environments that forgive nothing — and OT estates that attackers have noticed.

Oil & gas operators and equipment manufacturers run some of the world's most exposed OT estates on some of its longest-lived assets. Crest brings IACS cybersecurity under IEC 62443, mechanical engineering for harsh-environment equipment, and the data engineering that turns field telemetry into integrity and production decisions.
What this sector is actually up against
OT/IACS exposure across the value chain
From wellhead control to refinery DCS to terminal automation, converged IT/OT networks have made process control an attack surface. IEC 62443 zone-and-conduit discipline is now an operational necessity and, increasingly, an insurance condition.
Ageing assets, integrity obligations
Platforms, pipelines and rotating equipment run decades past original design life. Asset-integrity decisions need engineering analysis — FEA, fatigue assessment, reverse-engineered documentation for equipment whose OEMs no longer exist.
Harsh-environment equipment engineering
Equipment specified for offshore, desert and arctic service carries certification and material requirements that generalist design shops mishandle — and mistakes surface years later, in the field.
Digital oilfield without new attack paths
Production optimisation and predictive maintenance need field data in analytics platforms — but every new telemetry path is a potential route back into process control unless engineered one-way from the start.
Services mapped to the pressure
Cybersecurity & IEC 62443
IACS gap assessments, zone and conduit architecture and CSMS build for production-critical OT estates — sequenced around operations, not against them.
Mechanical Engineering
Design, FEA and reverse engineering for harsh-environment equipment; sustaining engineering and documentation recovery for long-lived assets.
IoT Engineering
Field telemetry, condition monitoring and asset tracking engineered with one-way data paths out of the process-control zone.
Cloud & Data
Production and integrity data platforms — historian integration, time-series pipelines and analytics for engineering and operations teams.
