Sector threat landscape

Cyber threats targeting energy and critical infrastructure

Energy is critical infrastructure. When a pipeline is disrupted, a power grid goes down, or a water treatment system is compromised, the impact extends far beyond the organisation. It affects economies, public safety, and national security.

01Nation-state targeting

Pre-positioning on critical infrastructure

State-sponsored groups conduct espionage, pre-position for disruption, and probe SCADA/ICS systems for vulnerabilities. Energy is consistently among the top three targeted sectors globally.

02Operational disruption

Ransomware on IT and OT estates

The Halliburton attack in August 2024 cost $35 million. Pipeline operators, refineries and utilities face ransomware campaigns that target IT and OT environments simultaneously.

03IT/OT convergence

Lateral movement into SCADA

Operational technology systems that were once air-gapped are now connected to IT for monitoring and remote management. Every connection is a potential lateral movement path from IT to OT, and SCADA/ICS run legacy software that cannot be patched without operational disruption.

In energy, cybersecurity is not about protecting data. It is about protecting physical operations, supply chains, and the infrastructure that societies depend on.

Cloudflare for energy

What we deploy for utilities and energy operators

A unified platform addressing the core cybersecurity challenges of the energy sector: IT/OT segmentation, SCADA remote access, DDoS protection for grid services, supply-chain API hardening, and DNS for OT-adjacent networks. One architecture across the five capability areas.

Plants, OT zones, conduits

IT/OT network segmentation across distributed energy sites

The most critical security measure in energy environments is preventing lateral movement between IT and OT networks. Cloudflare replaces legacy network architectures with granular, policy-based segmentation across pipelines, refineries, substations, and generation sites.

  • Magic WAN for policy-based segmentation between corporate IT and OT/SCADA networks
  • Gateway SWG for DNS filtering and outbound traffic control on OT-adjacent networks
  • Centralised firewall policies enforced across all sites without backhauling traffic
Regulatory alignment

Compliance built into the architecture

Compliance is not a layer added after deployment. It is built into the architecture from the first design workshop.

Sub-sectors

Cybersecurity across energy sub-sectors

Utilities

Water, gas, and electricity distribution operating large networks of smart meters, SCADA systems, and customer portals where the attack surface is vast and often under-secured.

  • WAF + bot management for customer portals
  • API Shield for smart-meter and IoT data
  • Gateway DNS for distributed infrastructure

Oil & Gas

Upstream, midstream, and downstream operations spanning offshore platforms and remote pipelines where SCADA controls physical processes and supply-chain integrity is critical.

  • Magic WAN for IT/OT segmentation across sites
  • Zero Trust Access for contractors
  • Gateway DNS for OT-adjacent networks

Renewables

Wind farms, solar installations, and battery storage geographically distributed and remotely managed, with secure data exchange to transmission operators.

  • Zero Trust Access for remote monitoring
  • Magic WAN between distributed sites
  • Argo Smart Routing for performance

Distribution

Generation, transmission, and distribution networks where grid stability depends on continuous availability of control systems and the resilience of management interfaces.

  • Magic Transit for grid management systems
  • Magic WAN for transmission segmentation
  • Zero Trust for control room access
Why Brixio

Why energy organisations choose Brixio for Cloudflare deployments.

Six reasons that come up across every utilities, oil and gas, renewables, and distribution engagement.

Full lifecycle

Others deploy and leave. Brixio operates long-term through managed services, reactive support, and emergency incident response. The architecture you receive on day one is the architecture we keep tuning.

IT/OT convergence practice

Dedicated IT/OT Convergence Security practice. OT-aware deployment methodology — IT-side controls first, then progressively to OT-adjacent networks. We do not deploy directly into SCADA/ICS process control.

GCC and European footprint

A dedicated hub in Dubai — the operational centre of the Gulf energy sector — and active clients across the EU. We understand both regulatory environments and the operational constraints of each market.

ASDP certified

Authorised Service Delivery Partner with direct escalation to Cloudflare engineering. Documented, auditable delivery process aligned with NIS2 and NERC CIP supply-chain requirements.

ISO 27001:2022

Compliance built into our own operations, not just our clients'. Independent audit, documented controls, and a security posture that holds up under critical-infrastructure due diligence.

FAQs

Energy cybersecurity & Cloudflare deployment

Magic WAN provides policy-based network segmentation between corporate IT networks and OT/SCADA networks without requiring traditional air gaps. Gateway adds DNS filtering to block malicious communications on OT-adjacent networks. Brixio designs the segmentation architecture during the energy architecture design phase, following IEC 62443 zone and conduit principles.

Yes. Cloudflare Access and Tunnel provide secure remote connectivity without requiring VPN infrastructure at each site. Zero Trust access controls verify user identity, device posture, and context before granting access to operational systems. This is particularly valuable for offshore platforms, remote pipelines, and distributed generation sites where traditional infrastructure is impractical.

Cloudflare's security stack maps directly to NIS2 requirements for essential entities: network security (Magic WAN, Magic Firewall), access control (Zero Trust Access, Gateway), incident detection (security event logging, DDoS alerts), and supply chain risk management (ASDP-certified delivery). Brixio delivers a compliance mapping as part of every energy engagement.

It depends on scope. IT-side controls (WAF, Zero Trust for remote access) can be deployed in 4-8 weeks. IT/OT segmentation with Magic WAN across multiple sites typically takes 8-16 weeks. Every engagement starts with a security assessment, and deployment follows industrial change management protocols.

OT environments have strict change management requirements. Brixio deploys IT-side controls first, then extends to OT-adjacent networks progressively. We do not deploy directly into OT/SCADA systems. Our approach focuses on securing the boundary between IT and OT through network segmentation, DNS filtering, and access control, while leaving process control systems untouched.

Yes. Brixio has a dedicated hub in Dubai and experience with Gulf energy operators. Our engineers understand NESA requirements and the specific operational constraints of oil and gas environments in the region.

Brixio offers three post-deployment options: managed services (ongoing operations for both IT and OT security controls), reactive support (credit-based L2/L3 assistance), or emergency incident response (engagement within 60 minutes). Energy organisations benefit from managed services that include continuous monitoring and proactive policy updates.
