NIS2 Compliance Guide: Achieving Continuous Compliance with HCL BigFix

Getting ready for NIS2 can be tough because it sets higher standards for security, governance, and leadership accountability. Organizations need to keep a close watch on their systems, respond to risks quickly, and be able to prove control at any moment. In this blog, we break down each NIS2 requirement in simple terms, highlight the business changes you will need to make, and explain how HCL BigFix helps enforce and sustain those controls through continuous compliance, endpoint compliance management, and automation.

The ENISA Threat Landscape 2025 shows that essential entities make up 53.7% of all reported cyber incidents in the EU. Sectors like public administration, transport, digital infrastructure, finance, and manufacturing are among the most targeted. These industries are also covered by the Network and Information Security Directive (NIS2) – Directive (EU) 2022/2555, which will be enforced in all Member States starting October 2024. The directive broadens regulatory requirements, gives supervisors more authority, holds executives accountable for cybersecurity failures, and requires fast incident reporting, including an early warning within 24 hours. NIS2 sets the security goals organizations must meet, but it’s up to security and IT teams to put them into practice. This is where tools like HCL BigFix play a critical role, enabling organizations to monitor risk, remediate issues, and generate audit-ready evidence at enterprise scale

The main challenge with NIS2 is making sure its requirements are applied consistently in complex environments. What needs to change at the endpoint level, and where are there gaps in visibility and enforcement? The following sections look at the directive in practical terms, linking the rules to the everyday work of security and IT teams.

The Core Mandate: Article 21

At the heart of NIS2 is Article 21, which outlines the specific Cybersecurity Risk-Management Measures that entities must implement. These are not suggestions; they are obligations.

The directive defines 13 key categories that organizations must address to manage risk effectively:

1. Risk Analysis and Information System Security

NIS2 requires organizations to establish policies and processes for ongoing risk analysis and system security. This requires maintaining an accurate and regularly updated understanding of vulnerabilities, misconfigurations, and asset changes across the environment. Without this visibility, emerging risks remain undetected, increasing the likelihood of incidents and weakening audit defensibility.

HCL BigFix continuously enforces secure configurations, provides near-real-time vulnerability visibility across endpoints, and prioritizes remediation using risk-based intelligence through CyberFOCUS.

2. Incident Handling

NIS2 requires defined procedures to detect, respond to, and manage cybersecurity incidents. Organizations must maintain system visibility, response workflows, and evidence to investigate and contain threats quickly. Weak incident readiness leads to prolonged disruptions, delayed regulatory reporting, and greater operational and reputational impact.

HCL BigFix accelerates containment by detecting unauthorized configuration changes, isolating compromised endpoints, and automating remediation across distributed environments.

3. Business Continuity and Disaster Recovery

NIS2 requires measures to ensure operational resilience, including backup validation, recovery readiness, and crisis management. Organizations must be able to contain the blast radius of incidents and restore systems to a secure state quickly. Poor recovery readiness increases downtime, disrupts critical services, and amplifies financial, regulatory, and customer impact.

HCL BigFix strengthens operational resilience by restoring hardened configurations, automating patching at scale, and enabling rapid bare-metal provisioning to return systems to a secure state.

4. Supply Chain Security

NIS2 requires organizations to manage cybersecurity risks introduced by third-party vendors and software components. This requires visibility into installed applications, versions, and dependencies across the environment. Unmanaged third-party exposure increases the risk of supply chain compromise and creates blind spots in risk and compliance assessments.

HCL BigFix provides deep visibility into third-party software, SaaS applications, and middleware versions, enabling rapid identification and remediation of supplier-related vulnerabilities.

5. Security in Acquisition, Development, and Maintenance

NIS2 requires systems to be securely configured and maintained throughout their lifecycle, including timely vulnerability remediation. Organizations must ensure patches, updates, and secure configurations are applied consistently across environments. Delays in remediation increase exposure to known exploits and are a leading cause of operational disruption and regulatory scrutiny.

HCL BigFix automates multi-platform patching, integrates with leading vulnerability scanners, and enforces continuous hardening across the entire system lifecycle.

6. Assessing the Effectiveness of Security Measures

NIS2 requires organizations to evaluate whether cybersecurity controls are functioning as intended. This requires ongoing measurement of control status and the ability to produce evidence over time. Point-in-time checks provide limited assurance and make it difficult to demonstrate sustained control during audits or investigations.

HCL BigFix delivers continuous compliance monitoring with historical reporting and audit-ready evidence to demonstrate sustained control effectiveness.

7. Basic Cyber Hygiene Practices

NIS2 requires foundational protections such as system hardening, secure configurations, and timely updates. Organizations must enforce baseline security standards consistently across all endpoints. Gaps in basic hygiene create preventable attack paths and significantly increase the organization’s overall risk exposure.

HCL BigFix enforces core cyber hygiene through continuous asset discovery, automated patch management, and persistent configuration baseline control.

8. Cryptography and Encryption

NIS2 requires policies governing the use of cryptography to protect sensitive data. Organizations must ensure encryption is properly implemented and consistently enforced across systems and devices. Weak or inconsistent encryption increases the risk of data exposure and escalates the impact of security incidents.

HCL BigFix validates encryption configurations, monitors certificate and protocol usage, and provides visibility into vulnerable cryptographic algorithms through a new offering– HCL Quantum Risk Analyser (QRA)

Below is a side-by-side analysis of the 2026 mandate requirements and how HCL BigFix Quantum Risk Analyzer (QRA) provides the specific capabilities needed for compliance.

9. Human Resources Security and Access Control

NIS2 requires controls to manage user access and reduce risks associated with personnel. This includes enforcing least-privilege access and regularly reviewing permissions. Excessive or outdated access rights increase the risk of insider threats, account compromise, and unauthorized system changes.

HCL BigFix enforces system-level access control configurations, audits privilege settings, and maintains unified visibility of assets across on-prem and SaaS environments.

10. Asset Management

NIS2 requires organizations to maintain an accurate inventory of systems and assets within scope. This requires identifying all devices and software in use, including remote and unmanaged environments. Unknown or unmanaged assets expand the attack surface and undermine the effectiveness of risk and compliance efforts.

HCL BigFix Inventory provides continuous, real-time visibility into hardware and software assets across hybrid environments, ensuring complete and accurate endpoint coverage.

11. Multi-factor Authentication and Identity Security

NIS2 requires strong authentication controls to protect system access. Organizations must ensure identity policies are implemented and consistently enforced across the environment. Authentication gaps remain one of the most common entry points for attackers and can lead to rapid lateral movement and system compromise.

HCL BigFix verifies and enforces authentication-related configuration settings, ensuring MFA and identity policies remain correctly implemented across managed endpoints.

12. Secure Voice, Video, and Text Communications

NIS2 requires protection of internal communications through secure technologies and configurations. Organizations must ensure collaboration platforms and communication channels are properly secured. Weak configurations can expose sensitive operational information and increase the risk of interception or unauthorized access.

HCL BigFix ensures collaboration platforms remain securely configured and fully patched through continuous compliance enforcement and automated third-party patching.

13. Physical and Environmental Security

NIS2 requires measures to protect systems from unauthorized physical access or environmental risks. This includes enforcing device-level protections and physical control policies. Physical compromise can bypass logical security controls, leading to data loss, system tampering, or regulatory exposure.

HCL BigFix enforces device-level security configurations and can automatically quarantine non-compliant endpoints to reduce exposure from compromised systems.

NIS2 Operational Summary: Continuous Compliance in Practice

Conclusion

NIS2 moves cybersecurity from periodic assessment to operational accountability. With stronger regulatory oversight, executive liability, and accelerated reporting requirements, organizations must be able to demonstrate continuous control over their environments.

Continuous endpoint compliance management is the operational foundation for meeting NIS2 expectations.

HCL BigFix enables organizations to maintain real-time visibility, enforce security controls, remediate risks automatically, and generate the evidence required to demonstrate effective cybersecurity governance under NIS2.
