What is NGFW and How It Supports NIS2 and DORA Compliance
Firewalls have long been the foundation of network defense. But in today’s world of encrypted traffic, SaaS applications, and sophisticated cyber threats, traditional firewalls are no longer enough.
Enter the Next-Generation Firewall (NGFW) – a smarter, more adaptive security technology.
NGFWs not only block or allow traffic; they understand applications, users, and content. That makes them essential not just for cybersecurity, but also for meeting modern regulatory requirements like NIS2 and DORA.
1. What is a Next-Generation Firewall (NGFW)?
An NGFW is an evolution of the classic firewall. Beyond packet filtering and port blocking, NGFWs provide:
Application control – Identify and manage traffic from apps like Microsoft Teams, Dropbox, or Zoom.
Intrusion Prevention System (IPS) – Detect and stop malicious activity in real time.
SSL/TLS inspection – Analyze encrypted traffic, where most modern threats hide.
User identity policies – Access rules based on who the user is, not just their IP address.
Threat intelligence integration – Real-time updates on emerging global threats.
2. NGFW vs Traditional Firewall
| Feature | Traditional Firewall | NGFW |
|---|---|---|
| Packet filtering | ✅ | ✅ |
| Stateful inspection | ✅ | ✅ |
| Application awareness | ❌ | ✅ |
| Intrusion prevention (IPS) | ❌ | ✅ |
| SSL/TLS inspection | ❌ | ✅ |
| User identity integration | ❌ | ✅ |
| Threat intelligence feeds | ❌ | ✅ |
3. Why NGFW Matters Today
Hybrid work: Protects beyond the office perimeter.
Cloud adoption: Visibility and control across SaaS and multi-cloud.
Advanced threats: Goes beyond simple blocking to prevent zero-days and targeted attacks.
4. NGFW and Regulatory Compliance
NIS2 Directive
Requires network and information system risk management.
NGFW supports compliance by:
enabling network segmentation,
enforcing supply chain traffic controls,
providing logs for incident reporting within 24h.
DORA Regulation
Focuses on digital operational resilience in finance.
NGFW helps by:
protecting critical financial applications (payments, online banking),
offering encrypted traffic inspection to detect fraud and malware,
integrating with SOC/XDR for compliance-ready reporting to regulators.
5. The DIAMATIX Perspective
NGFWs are no longer “just a box at the perimeter.” They are a compliance enabler and a key part of resilient infrastructure.
At DIAMATIX, we deliver NGFW, powered by industry leaders like Fortinet and Check Point, fully integrated into our Shield SIEM/XDR platform and monitored by our 24/7 SOC team.
This way, organizations not only tick the compliance box under NIS2 and DORA – they achieve real-time protection, resilience, and long-term trust.
