How modern DFIR capabilities support meeting the NIS2 Directive

By Andrea Hruska

The NIS2 Directive introduces stricter cybersecurity requirements across essential and important sectors, expanding accountability beyond prevention and detection into response, investigation, and reporting.

Organizations and public sector entities in the EU or serving EU entities are now expected to:

• Detect and respond to incidents quickly
• Understand what happened, how, and what data was impacted
• Report within 24 hours (early warning) and 72 hours (detailed update)
• Maintain auditability and defensibility of their actions

This creates significant urgency and exposes a gap many organizations aren’t equipped to fill: performing deep, defensible investigations across endpoints, cloud, and mobile.

This is where modern digital forensics and incident response (DFIR) capabilities become essential.

What is NIS2?

The NIS2 Directive is EU-wide cybersecurity legislation that replaces the original 2016 NIS Directive. Its goal is to establish a common cybersecurity standard across EU member states and address the growing scale and sophistication of cyber threats targeting critical infrastructure and digital services.

NIS2 expands upon the original directive to cover more sectors, introduces stricter incident reporting obligations, and holds senior management directly accountable for cybersecurity risk.

What is digital forensics and incident response (DFIR)?

Meeting NIS2’s requirements for investigation and defensible reporting depends on a capability many security teams underinvest in: DFIR.

Digital forensics and incident response (DFIR) are complementary disciplines that enable organizations to contain threats quickly while preserving the data needed to understand and reduce impact.

Incident response focuses on detecting, containing, and remediating security incidents. Its goal is to limit damage and restore operations as quickly as possible.

Digital forensics focuses on investigating incidents by collecting, analyzing, and preserving digital evidence. It enables teams to reconstruct events, determine root cause, and understand the full scope of impact, with findings that can support regulatory, legal, and insurance requirements.

DFIR capabilities enable organizations to:

• Identify artifacts left by threat actors through historical data analysis (e.g., malware, scripts, emails)
• Conduct threat hunting and pattern matching (e.g., using YARA or searching for identifiers by keyword)
• Reconstruct a defensible timeline of events for reporting and audit purposes

Why do I need a DFIR solution when I have an EDR/XDR in place?

DFIR and EDR/XDR solutions complement each other and are both essential for a complete incident response plan.

EDR/XDR solutions provide valuable telemetry data and alerts that aid in the early detection of security incidents, which can then be further investigated and validated through DFIR processes. But detection is only the first step.

DFIR techniques, expertise, and solutions are essential for conducting thorough investigations, analyzing attack vectors, and understanding the full scope and impact of security incidents. DFIR capabilities provide deeper understanding by acquiring and analyzing data at a very granular level from endpoints, servers, cloud, and other data sources to identify exactly how a security incident happened, what data was compromised, and who the threat actor is.

Where do NIS2 requirements intersect with DFIR?

There are four key areas where DFIR supports meeting NIS2 requirements:

• Preservation and investigation of digital evidence during and after cyber incidents.
• Reconstruction of events to support incident reporting and oversight.
• Defensible documentation for supervisory authorities, auditors, and, where applicable, judicial proceedings.
• Post incident reviews to demonstrate due diligence and lessons learned.

What are the repercussions of non-compliance?

Fines can reach up to €10 million or 2% of global annual turnover for essential entities , whichever is higher, and €7 million or 1.4% for important entities. Beyond financial penalties, NIS2 places clear responsibility on management to oversee cybersecurity risk and ensure appropriate controls are in place.

Regulators (different for each member state ) are empowered to enforce compliance through audits, inspections, and remediation orders, with specific consequences varying by country. Organizations and public entities may also be required to demonstrate how incidents are investigated, reported, and resolved.

Importantly, requirements like the 24-hour early warning and 72-hour notification are designed not just to penalize delays, but to ensure organizations respond effectively and communicate clearly during incidents.

How Magnet Forensics’ solutions help you meet NIS2 compliance

Meeting NIS2’s tight timelines requires more than detection. It requires the ability to investigate, analyze, and report on incidents with speed and defensibility.

Magnet Forensics’ portfolio is built to support each stage of that process.

Remote collection and AI-powered analysis with Magnet Axiom Cyber and Magnet Review

• Remotely acquire evidence from endpoints across your organization without physical access, critical when the clock is ticking.
• AI-powered analysis tools surface relevant findings instantly from massive datasets, turning days of manual analysis into hours.
• Timeline and Connections visualizations provide immediate clarity on attack progression.
• YARA rules and MITRE ATT&CK framework integration enable rapid threat identification for compliant reporting.

24/7 automated and integrated workflows with Magnet Automate

• Keep investigations running around the clock, processing multiple items of evidence in parallel without staffing increases.
• Build standardized workflows once; execute them consistently every time.
• Integrate across your forensic and security stack (XDR/EDR, SIEM, SOAR) to eliminate manual handoffs and reduce delay between alert and collection, ensuring no critical data is lost.
• Automatically update stakeholders as investigations progress (for example, trigger Slack updates to let your team know when data processing is complete and ready for review).

Real-time collaboration for all stakeholders with Magnet Review

• Share data securely with investigators, legal, compliance, and other non-technical stakeholders from anywhere, in real-time.
• Intuitive interface lets non-technical users, including executives with personal liability, engage directly with the data.
• Filter, search, and tag noteworthy artifacts together for immediate alignment across your teams.
• Maintain chain of custody and audit trails for regulatory reporting.

Enterprise-scale remote data collection with Magnet Nexus

• Be ready for an incident — deploy across your entire infrastructure and collect from multiple endpoints simultaneously.
• Real-time artifact processing surfaces critical findings as data is collected and processing, not hours later.
• Cloud-based scalability handles unexpected surges without additional hardware.
• Get more done together with collaborative workflow distributes case setup, tagging, and filtering across your team.
• Control where data is stored with a unique hybrid collection agent approach.

Taking the next steps

For organizations and governments facing NIS2 compliance deadlines, the path forward involves:

1. Assessing current capabilities: Evaluate existing capabilities against NIS2’s specific requirements for data preservation, analysis, and reporting timelines.
2. Implementing forensic-grade tools: Deploy solutions like Magnet Axiom Cyber, Automate, Review, and Nexus that are specifically designed for enterprise-scale digital investigations (especially those under regulatory timeline constraints).
3. Developing automated workflows: Create standardized, documented incident response workflows that ensure consistent handling of events and maintain compliance with reporting requirements.
4. Enabling stakeholder collaboration: Establish secure, accessible platforms for coordinating between technical teams, management, and external authorities.
5. Conducting regular testing: Organizations must conduct tabletop exercises to test the effectiveness of their IR playbooks, validating that forensic capabilities can meet NIS2’s strict timelines.

Be prepared with investigative readiness

When the 24-hour clock starts, investigative readiness is what separates organizations that respond with confidence from those that scramble. Magnet Forensics’ solutions are
