Cybersecurity for:
Energy Sector
Energy sector cybersecurity covers critical infrastructure protection, SCADA/ICS systems, smart grid, and IT/OT convergence. Discover threats and solutions for the energy industry.
90% of energy companies experienced at least one OT cybersecurity incident in the past 2 years

Top Threats
Wiperware
Destructive malware that permanently destroys data and systems. The DynoWiper attack on Polish energy infrastructure (December 2025) demonstrated the severity of this threat.
State-sponsored APT attacks
APT groups (Sandworm, Volt Typhoon) target energy infrastructure as part of hybrid warfare and geopolitical leverage.
SCADA/ICS exploitation
Industrial control systems often run on legacy protocols without encryption, making them easy targets for attackers.
Supply chain attacks
Compromising software and firmware vendors for energy systems provides access to multiple operators simultaneously.
OT ransomware
Ransomware spreading from IT to OT networks can halt energy production and distribution for hours or days.
Regulatory Requirements
NIS2
Energy operators classified as essential entities must implement risk management, 24/7 monitoring, and 24h incident reporting.
IEC 62443
International standard for industrial automation security — required by regulators and insurers across the energy sector.
NERC CIP
North American standard for critical infrastructure protection in the energy sector — relevant for international operations.
Why energy cybersecurity requires a specialized approach
The energy sector is the backbone of every nation’s critical infrastructure. A cyberattack on energy systems doesn’t just disrupt power supply — it paralyzes hospitals, transportation, telecommunications, and the entire economy. The DynoWiper attack on Polish energy infrastructure in December 2025 confirmed that the threat is real and directly affects our region.
IT/OT convergence creates new attack vectors. SCADA and ICS systems designed decades ago without cybersecurity in mind are now connected to corporate networks and the internet, exposing them to threats they were never designed to handle.
Biggest threats to the energy sector
Wiperware — destruction without recovery
Unlike ransomware, wiperware doesn’t demand ransom — its sole purpose is to destroy data and systems. The DynoWiper attack demonstrated that energy companies are direct targets of such operations.
APT attacks on critical infrastructure
Groups like Sandworm (responsible for BlackEnergy and Industroyer) systematically target the energy sector as part of hybrid warfare. Smart grid and modern energy distribution systems expand the attack surface.
IT/OT convergence gaps
Connecting corporate IT networks to operational OT networks without proper segmentation enables lateral movement from a compromised workstation to PLC controllers managing physical processes.
Regulatory requirements
NIS2 classifies energy operators as essential entities, mandating risk management, continuous monitoring, 24h incident reporting, and regular audits. IEC 62443 defines security requirements for industrial automation systems used in the energy sector.

Frequently Asked Questions
Why is the energy sector a target for cyberattacks? ▼
Energy infrastructure is a strategic target — its disruption paralyzes the entire economy. APT groups use this as geopolitical leverage in hybrid warfare.
How does OT security differ from IT security? ▼
OT systems prioritize availability and physical safety over confidentiality. They require specialized tools, protocols, and approaches — standard IT solutions can disrupt industrial processes.
What is IEC 62443 and is it mandatory? ▼
IEC 62443 is the international standard for industrial automation security. While not always legally mandatory, it is required by regulators, insurers, and business partners.
How to secure SCADA systems? ▼
IT/OT network segmentation, OT traffic monitoring, controller hardening, vulnerability management, and regular industrial system security audits.
Where to start with energy cybersecurity? ▼
OT security audit to identify gaps and risks, then network segmentation, OT monitoring deployment, incident response planning, and staff training.
