What is NIS2?
The European Union’s NIS2 Directive represents a fundamental shift in how organisations must approach digital security. Driven by an increasingly complex, interconnected and aggressive cyber threat landscape, NIS2 moves beyond traditional, checklist-based compliance to mandate true operational cyber resilience.
For organisations operating within the EU, NIS2 fundamentally elevates cybersecurity from an IT concern to a boardroom imperative. It mandates an "all-hazards" approach to risk management — the ability to respond to any threat while building overall operational resilience — expands its reach across critical supply chains while demanding a proactive, unified strategy to protect network and information systems. The goal is no longer just preventing attacks, but ensuring the continuous, secure delivery of essential services to the European economy and society, even when disruptions occur.
To enforce this culture of resilience, NIS2 is highly prescriptive. It introduces specific legislative mandates that make the deployment of advanced cybersecurity solutions a legal requirement, not just an operational best practice.
Key objectives of the NIS2 Directive
The primary objective of the NIS2 Directive is to establish a harmonised, elevated baseline of cybersecurity across European critical infrastructure, moving beyond traditional IT to encompass the operational technology (OT) that keeps our societies functioning.
The most significant shift NIS2 brings is its sheer scope and its strict demand for board-level accountability. It explicitly recognises that systems like Land Mobile Radio (LMR) networks are no longer isolated islands; they are converged ecosystems where a breach in an enterprise IT environment can swiftly compromise public safety communications.
Ultimately, NIS2 aims to force organisations to transition from reactive scrambling to proactive, intelligence-driven defence, ensuring that the critical communications we rely on remain resilient under attack.
Who does NIS2 apply to?
The NIS2 Directive casts a significantly wider net than its predecessor, moving beyond traditional utilities to encompass a vast array of industries. In practical terms, NIS2 applies to all medium and large enterprises, specifically those with 50 or more employees or an annual turnover exceeding €10 million — operating within 18 designated sectors across the European Union.
These are divided into “Essential” entities, such as energy, transport, healthcare and digital infrastructure, and 'Important' entities, which include manufacturing and waste management. For those of us managing mission-critical Land Mobile Radio (LMR) networks, the implications are direct. If your organisation relies on LMR for public safety, transportation logistics or utility operations, your converged IT and OT communications infrastructure falls squarely into the highly critical Essential category. This means your entire ecosystem, from the dispatch consoles to the broadband gateways, is bound by NIS2 compliance and its stringent reporting mandates.
What NIS2 requires
By mandating "appropriate and proportionate technical, operational and organisational measures" (Article 21), the directive explicitly requires organisations to invest in active, continuous security capabilities. Specifically, the law demands technical solutions that deliver:
- Continuous monitoring and rapid detection (Article 23): The requirement to report significant incidents to authorities within 24 hours makes relying on manual log reviews legally untenable. Organisations must adopt continuous, automated threat monitoring to meet these narrow reporting windows.
- Active incident handling (Article 21(2)(b)): The law requires formalised incident handling capabilities for incident detection, analysis and containment — necessitating the use of active detection and response platforms such as MDR (Managed Detection and Response) or SOAR (Security Orchestration, Automation and Response) to demonstrate that appropriate measures are in place.
- Vulnerability management (Article 21(2)(e)): Entities must continuously secure their network and information systems, making vulnerability scanning, patch management and threat intelligence solutions a legal imperative.
- Identity and access control (Article 21(2)(j)): The directive explicitly dictates the deployment of Multi-Factor Authentication (MFA), continuous authentication and secured communications across organisational infrastructure.
Critically, Article 20 places the liability directly on the management body — holding leadership personally accountable for approving and overseeing the implementation of these measures.

Key impacts of the NIS2 Directive
- Expanded scope (Articles 2 & 3): The law categorises a broader range of businesses into "Essential" and "Important" entities. This spans sectors of high criticality including energy, transport, banking, health, drinking water and digital infrastructure.
- Stringent incident reporting (Article 23): Entities must submit an early warning to their competent authority or CSIRT within 24 hours of becoming aware of a significant incident. This must be followed by a detailed incident notification within 72 hours and a final comprehensive report within one month.
- Management accountability (Article 20): Management bodies are legally required to approve cybersecurity risk-management measures, oversee their implementation and can be held directly, personally liable for infringements.
- Severe financial penalties (Article 34): Essential entities face fines of up to €10,000,000 or 2% of the total worldwide annual turnover — whichever is higher. Important entities face fines of up to €7,000,000 or 1.4% of global turnover.
The Implementing Regulation requirements
While the main Directive establishes the legal and financial framework, the Commission Implementing Regulation dictates the exact technical and methodological standards that entities within the Digital Infrastructure, ICT Service Management and Digital Provider sectors must adopt to prove compliance. It translates broad risk-management goals into concrete, auditable IT requirements:
- Continuous monitoring & Logging (Art. 3.2): Organisations are legally required to continuously monitor and log activities to detect events. The regulation specifically mandates the deployment of systems that minimise false positives and negatives, alongside the regular review of logs for unusual trends.
- Structured incident response (Art. 3.4 & 3.5): Demands formal, documented capabilities for event assessment, classification and timely incident response, encompassing containment, eradication and recovery.
- Active threat protection (Art. 6.7 & 6.9): Mandates robust network security architectures and the deployment of active detection and response tools to protect systems against malicious software and unauthorised access.
- Physical & environmental security (Art. 13): Extends cybersecurity to physical premises, requiring strict physical access controls, security perimeters and continuous monitoring to prevent unauthorised access or environmental damage to critical IT infrastructure.
Preparing for NIS2: From policy to operational resilience
Complying with NIS2 is rarely a journey an organisation should undertake alone. It requires more than just updating internal policies; it demands a shift to active and continuous operational security. The regulations dictate that we must move beyond passive defences and implement systems capable of detecting and responding to threats in real time.
Key operational steps for compliance
To truly align with the Implementing Regulations, security leaders must operationalise their strategy across several critical areas:
- Establish continuous visibility: Implementing continuous monitoring and logging is legally required to detect events across your infrastructure. You must deploy systems that minimise false positives and negatives alongside the regular review of logs.
- Automate threat assessment: Leveraging automation and orchestration technologies assists in event assessment and classification. This allows skilled analysts to use predefined playbooks to quickly triage critical incidents.
- Formalise incident response: The regulation demands formal and documented capabilities for timely incident response. This must encompass the containment, eradication and recovery of threats.
- Implement active protection: Deploying robust network security architectures and active detection tools is mandated to protect systems against malicious software and unauthorised access.
Building a complete security ecosystem
Securing converged Land Mobile Radio (LMR) and IT networks requires an ecosystem approach. Much like building watertight bulkheads on a ship to prevent a single breach from sinking the vessel, separating and securing your IT and OT environments requires deep technical expertise and round-the-clock vigilance. This is where partnering with a mature security provider becomes a strategic advantage.
