Strengthen NIS2 Compliance with Continuous Firewall Policy Control
Continuously monitor firewall policy, validate segmentation protecting critical systems, and produce audit-ready evidence across multi-vendor, hybrid environments. One consistent view of policy spans interconnected on-premises, cloud, and segmented networks, connecting NIS2 Article 21 security intent to the controls that enforce it.
[ Keep NIS2 Evidence Current as Network Environments Change ]
NIS2 Article 21 requires network security and access controls that stay demonstrably effective. Manual reviews across multi-vendor firewalls and cloud environments leave gaps between assessments.
Security Manager normalizes policy across 120+ platforms, including leading firewalls, cloud platforms, and microsegmentation tools, for one consistent view across every enforcement point. That foundation drives the firewall visibility, change governance, and audit evidence behind NIS2 Article 21.
Turn firewall policy data into defensible NIS2 audit evidence.
Connect NIS2 Article 21 Requirements to Enforced Network Policy
NIS2 Article 21 requires essential and important entities to implement appropriate and proportionate technical, operational, and organizational cybersecurity risk-management measures. FireMon supports the network-policy evidence and control activities relevant to several Article 21 requirement areas.
FireMon does not cover the full directive, provide legal advice, or independently certify NIS2 compliance.
NIS2 Article 21 Requirement
Article 21(2)(a) Risk Analysis and Information System Security
Article 21(2)(b) Incident Handling
Article 21(2)(e) Security in Network and Information Systems Acquisition, Development, and Maintenance
Article 21(2)(f) Assessing Effectiveness of Cybersecurity Risk-Management Measures
Article 21(2)(i) Access Control Policies and Asset Management
How FireMon Supports
Assess firewall and cloud policy against defined security controls, identify policy gaps, and maintain current assessment results.
Use access-path analysis, recent policy changes, and change history as network context for investigating incidents and potential exposure.
Evaluate proposed policy changes before implementation and preserve a documented record of governed change activity.
Run repeatable policy assessments, track failures and remediation, and retain evidence showing how network controls were reviewed.
Analyze permitted access, rule ownership, business justification, exceptions, and segmentation around critical assets and services.
[ Feature Deep Dive ]
Turn NIS2 Requirements into Measurable Policy Controls
Assess firewall and cloud policies against applicable NIS2 expectations and internal security standards. Identify risky access, policy gaps, configuration weaknesses, and unintended paths that could expose member information or critical services.

Support NIS2 Alongside Related Compliance Frameworks
Financial institutions rarely manage one compliance requirement at a time. FireMon helps teams assess network policy against NIS2 expectations alongside related standards and regulations, reducing duplicate work while preserving the evidence each review requires.
Federal security control compliance with automated mapping and continuous monitoring.
Assess network policy continuously against applicable HIPAA security requirements.
Digital operational resilience compliance for financial services organizations.
Automate PCI DSS 4.0 compliance for network segmentation and firewall policy requirements.
Sarbanes-Oxley compliance for IT controls and change management.
Critical infrastructure protection compliance for energy and utilities.

NIS2 Compliance Frequently Asked Questions
NIS2, Directive (EU) 2022/2555, establishes a common EU framework for improving cybersecurity across 18 critical sectors. It expands the scope of the original NIS Directive and introduces cybersecurity risk-management, incident reporting, governance, supervision, and enforcement requirements. Member States were required to transpose the directive into national law, so organizations must also account for the specific law and regulator that apply in each country.
NIS2 applies to essential and important entities in covered sectors, including energy, transport, banking, financial market infrastructure, health, drinking water, wastewater, digital infrastructure, ICT service management, public administration, space, and additional sectors. Scope depends on factors such as entity type, size, sector, national implementation, and specific designation, so organizations should confirm applicability with legal and regulatory counsel.
Article 21 requires appropriate and proportionate cybersecurity risk-management measures. Relevant areas include risk analysis and information system security, incident handling, security in network and information systems acquisition and maintenance, procedures to assess control effectiveness, and access control and asset management. FireMon supports the firewall and network-policy evidence relevant to these areas, but it does not cover every NIS2 requirement.
NIS2 does not prescribe one specific firewall product or one universal segmentation architecture for every covered entity. It requires risk-based technical, operational, and organisational measures for network and information system security and access control. Firewall policy governance and segmentation can support those requirements by limiting access, isolating critical systems, and providing evidence that network controls remain effective.
FireMon centralizes policy analysis across supported multi-vendor, cloud, and microsegmentation environments, identifying unnecessary access, evaluating proposed changes, and maintaining change and review evidence for repeatable compliance assessments and reporting. FireMon supports the network-policy portion of an NIS2 program and does not independently certify or guarantee NIS2 compliance.
