NIS2 Compliance for On-Premise OT.
NIS2 requires network segmentation, access control, incident detection, and supply chain risk management. Access Gate enforces Article 21 measures on-premise, across IT and OT, with sovereign European technology. No data leaves your network.
What is NIS2 on-premise compliance?
NIS2 (Network and Information Systems Directive 2) is the EU cybersecurity directive that requires essential and important entities to implement risk management measures across their IT and OT infrastructure. On-premise compliance means enforcing these measures directly on your local network, keeping all data, logs, and policy enforcement within your facility. For organizations operating in regulated European sectors, this means sovereign technology with no cloud dependency.

Article 21 security measures enforced by Access Gate at the network layer: segmentation, access control, incident detection, and continuous audit trail.
NIS2 applies to essential entities (energy, transport, health, water, digital infrastructure) and important entities (manufacturing, food, chemicals, waste, postal, research) operating in the EU. If you operate critical infrastructure or supply essential services, you are likely in scope. Member state transposition may expand coverage further.
Article 21 requires risk management measures including network segmentation, access control, incident detection, asset inventory, supply chain risk management, and business continuity. For OT environments, these measures must work without disrupting production and without requiring agents on legacy equipment.
Yes. Access Gate runs entirely on-premise. Policy enforcement, session logging, incident detection, and audit trail generation all happen locally. No data leaves your network. This satisfies both NIS2 requirements and EU data sovereignty expectations.
Essential entities face fines up to 10 million EUR or 2% of global annual turnover, whichever is higher. Important entities face up to 7 million EUR or 1.4% of turnover. Senior management can be held personally liable for insufficient risk management measures.
NIS2 expands the scope to more sectors, introduces personal liability for management, raises penalties, adds supply chain security requirements, and mandates 24-hour incident notification. It also removes the distinction between operators of essential services and digital service providers, replacing it with essential and important entity categories.
NIS2 requires organizations to manage supply chain risk and ensure security of their information systems. Using cloud services that transit data through non-EU jurisdictions creates legal and operational risk. On-premise deployment with European-developed technology eliminates this exposure.
Access Gate deploys in hours. It connects to your existing network without changes to switches, cabling, or IP addresses. Asset discovery begins immediately. Access policies and segmentation can be configured within days. Full Article 21 evidence generation is operational within weeks.
Yes. IEC 62443 zone and conduit architecture maps directly to Access Gate overlay segmentation. Organizations subject to both NIS2 and IEC 62443 can satisfy both with a single deployment. The same session logs, access policies, and segmentation baselines serve as evidence for both frameworks.
