EU-Regulated Organisations Since 2002
Since 15 January 2026, Sweden’s Cybersäkerhetslag (2025:1506) has implemented the NIS2 directive in Swedish law, and many Swedish energy operators are within scope, depending on their activities, size and any applicable exceptions. The covered subsectors are electricity, district heating and cooling, oil, gas and hydrogen. NIS2 also expressly includes district heating and cooling within the energy-sector scope.
For the board, the shift is direct responsibility for approving and overseeing cybersecurity measures. For the security lead, it means knowing the map: Energimyndigheten supervises, incidents are reported to NCSC/CERT-SE, and the rigour you apply in the control room now has to reach every system that can touch operations.
Electricity, district heating and cooling, oil, gas and hydrogen are all in scope, with coverage depending on your size and activity. District heating is caught for the first time.
Article 23 sets 24-hour, 72-hour and one-month reporting stages. Significant incidents are reported to NCSC through the national Cyberportal.
Article 21 requires appropriate supply-chain security, including assessment of relevant direct suppliers, service providers and remote-access dependencies.
The organisation’s management must approve and oversee the required cybersecurity measures and complete relevant training. Administrative fines apply to the entity, not to individuals personally.
Many operators rely on ageing control systems, internet-exposed edge devices and vendor remote-access paths that have never been fully reviewed. Energy cybersecurity is now a question of availability, not just data, which is exactly why cybersecurity in the power sector cannot wait until after an incident.
In May 2023, attackers exploited Zyxel firewall vulnerabilities to compromise 22 Danish energy companies. Some affected operators isolated systems as a precaution while the incidents were investigated. SektorCERT described it as an unusually large, coordinated attack on Danish critical infrastructure.

In October 2025, Svenska kraftnät, Sweden’s national grid operator, confirmed a breach involving a limited external file-transfer solution. The Everest ransomware group claimed to have stolen around 280 GB of data. Svenska kraftnät said the electricity system and mission-critical systems were not affected.

No spam. Sweden-based data handling. Unsubscribe any time.
Whatever your operation runs into, one partner covers it: identities, vendor access, control-room adjacency, edge devices, compliance, all of it.
Protect Your Data as AI Spreads
AI tools are spreading into day-to-day work, which creates new routes for data exposure, misuse and AI-assisted phishing. AIDR helps identify unsanctioned AI use and suspicious AI-related activity across your business environment.
Watch the Paths into Your OT
Building an internal night shift just for threat monitoring is not realistic for most operators, so our Sweden-based SOC provides continuous coverage of endpoints, identities and the vendor remote-access paths around your OT, with MDR adapted to energy-sector environments.
Find the Gap Before an Attacker Does
We test agreed web, cloud and network environments, including safely scoped checks of IT/OT boundaries and internet-facing infrastructure. Testing is planned around operational safety, availability and maintenance windows.
Protect Staff from Phishing
Phishing and credential theft can give attackers an initial foothold in business systems before they move toward operational environments. Short, role-based lessons and realistic phishing tests for control-room, field and office staff, with results you can see from week one.
Protect Leadership from Blind Spots
Not every operator needs, or can recruit, every senior security capability internally. You get support for NIS2 readiness, supervisory expectations and incident-reporting processes, scaled to what you actually need.

Many Swedish energy operators are covered. The law applies to relevant activities in electricity, district heating and cooling, oil, gas and hydrogen, normally where the organisation meets the applicable size threshold. Smaller operators may also be included where their services are particularly critical. Each legal entity should assess its own position and register if covered. Energimyndigheten supervises the energy sector.
Essential entities may face administrative fines of up to €10 million or 2% of worldwide annual turnover, whichever is higher. Important entities may face up to €7 million or 1.4%. Management must approve and oversee cybersecurity measures and complete appropriate training. In serious cases, authorities may also seek restrictions against individuals holding management positions.
A significant incident generally requires an early warning within 24 hours, an incident notification within 72 hours and a final report within one month. Reports are submitted to NCSC through the national Cyberportal. CERT-SE can provide support during an ongoing incident, while Energimyndigheten remains the supervisory authority for the energy sector.
Office IT can usually be patched, rebooted and taken offline when needed. The systems that run a power grid, a substation or a district heating plant cannot, because keeping electricity and heat flowing comes first and even a short interruption has real consequences. This operational equipment often stays in service for decades, uses specialist industrial protocols and offers very limited maintenance windows. Protection cannot rely only on frequent patching and rebooting. It depends more on careful segmentation, closely monitored remote access and working hand in hand with your engineering teams.
Yes. Wind, solar and battery-storage environments often include distributed assets, remotely managed controllers, inverters, gateways and third-party platforms. Weak credentials, exposed interfaces, outdated firmware and poorly controlled vendor access can create routes into operational environments. These assets should be inventoried, segmented and continuously monitored.
The exact data set varies by operator, but it commonly includes smart-meter readings, customer and billing information, and staff records. The volume and sensitivity vary by operator. Meter data can reveal when a household is home, so it deserves real care, even though an energy company’s biggest risk is disruption to supply rather than data theft. Protecting it comes down to controlling who can access it, keeping it inside well-managed systems, and watching for unusual access.
The security logs and telemetry we collect are handled on Sweden-based infrastructure, designed to support GDPR and international data-transfer requirements. This is set out in the service agreement rather than left as a general claim, and full data-flow documentation is available for your data protection officer and for procurement review.
MDR watches the systems that sit around your operational environment. That means the endpoints, logins, cloud services, network activity and remote-access routes that connect to your grid or plant. The goal is to catch an attacker in business IT before they can move toward the control systems that keep power and heat running. What we monitor is agreed with your engineering team, and nothing is deployed into OT without a plan you have signed off. Analysts investigate alerts around the clock and hand you the incident evidence you need for NIS2 reporting.
No. MDR works alongside your internal IT and OT teams. Your engineers continue to manage infrastructure and operational systems, while our SOC focuses on detection, investigation and response. Escalation paths are agreed during onboarding so everyone knows who acts when an alert appears.
Usually within about 72 hours. That is once access, approvals and technical prerequisites are in place, and the exact timeline still depends on your environment, integrations and agreed scope. OT boundaries and escalation procedures are defined with your team before monitoring begins.
No. Onboarding is designed to avoid any disruption to normal operations, and initial deployment focuses on approved IT systems and the management tools you already use. Nothing is introduced into the OT environment without a documented plan agreed with your engineering team.
MDR is priced per endpoint per month with a fixed monthly fee. There are no hidden charges for incident response, analyst escalation or alert volume. This makes costs predictable for energy-sector budgets. We provide a clear written proposal after the initial briefing, with no obligation.
eBuilder Security combines a Sweden-based SOC, named analysts and knowledge of the Swedish regulatory environment. Energy operators receive locally accountable support, predictable communication and services aligned with Energimyndigheten supervision and national incident-reporting requirements. The right choice depends on your technical environment, risk profile and data-handling requirements.
