Firewall and NGFW Implementation
91% of attacks start from network traffic. Next-generation firewall blocks threats before they reach systems. We design, implement and maintain Fortinet and Cisco solutions with 99.9% SLA.

What is a Next-Generation Firewall (NGFW)?
A Next-Generation Firewall (NGFW) is an advanced network device combining traditional traffic filtering with SSL/TLS inspection, IPS, application control, and zero-day threat protection. nFlo designs, implements, and maintains Fortinet and Cisco solutions with 99.9% SLA — deployment within 2 weeks.
Traditional firewalls don't see 80% of modern threats

Firewall Let Ransomware Through for 3 Months
Logistics company had traditional firewall checking only ports and IP. Ransomware communicated with C2 via HTTPS (port 443) - firewall passed it without inspection. Malware waited 3 months collecting data and privileges. Weekend attack: 90% systems encrypted. Cost: €2M downtime + €50k ransom.
Without modern NGFW:
- No encrypted traffic inspection (80% of attacks hidden in SSL/TLS)
- No application control - only ports (Dropbox = Facebook = HTTPS:443)
- Don’t know who connects where (no user identification)
- Don’t meet NIS2, PCI DSS and cyber insurance requirements
Complete Implementation - From Design to 24/7 Support
We don’t just sell hardware. We design architecture matched to your business, migrate rules without downtime, train team and provide 24/7 support with 99.9% SLA. You know your network is protected by experts.
What you get:
- Environment assessment and requirements analysis (security, performance, HA)
- Architecture design (standalone, HA, clustering, SD-WAN)
- Solution selection matched to budget and requirements
- Migration from existing firewall without production downtime
- Security policy configuration (App Control, IPS, AV, SSL inspection)
- Integration with Active Directory, SIEM, NAC

- Documentation (network diagrams, policy matrix, runbooks)
- IT team training on management and troubleshooting
- Optionally: managed firewall 24/7 from us
Who Is It For?
This service is for you if:
- You have outdated firewall and need upgrade to NGFW
- You’re expanding infrastructure and need new locations
- You’re subject to NIS2, PCI DSS and need compliance
- You want visibility and control over application traffic
- You need expert support - don’t have in-house resources
Why NGFW?
Next-Generation Firewall is more than traditional firewall:
NGFW vs Traditional Firewall Capabilities
| Function | Traditional FW | NGFW |
|---|---|---|
| Port/IP Control | ✓ | ✓ |
| Application Control | ✗ | ✓ (e.g., block Facebook, YouTube) |
| User Identity | ✗ | ✓ (AD integration) |
| SSL/TLS Inspection | ✗ | ✓ (scans encrypted traffic) |
| IPS/IDS | Optional | ✓ built-in |
| Advanced Malware Protection | ✗ | ✓ (sandboxing, AI) |
| Threat Intelligence | ✗ | ✓ (updates every 5 min) |
| Reporting | Basic | Advanced dashboards |
Use Case Examples
Application Control: “Block Dropbox for everyone except IT department”
User-based policies: “Marketing can access YouTube, finance cannot”
SSL Inspection: “Scan encrypted traffic for malware”
Geo-blocking: “Block connections from Russia, China, North Korea”

Common questions about Firewall and NGFW Implementation.
How much does NGFW firewall implementation cost?
Implementation project (work): from €7,500 for simple standalone, €12,500-20,000 for HA cluster with migration. Hardware: Fortinet from €3,750, Cisco from €7,500. Annual licenses: 20-40% of hardware price.
How long does firewall implementation take?
Simple standalone firewall: 1-2 weeks. HA cluster with legacy migration: 4-6 weeks. Includes assessment, design, implementation, tests and training. Rule migration happens without production downtime during maintenance window.
Can you take over management of existing firewall?
Yes - we support Fortinet and Cisco. First we do health check, update firmware/licenses, then take over 24/7 management. Managed firewall model from €1,250/month with 4h SLA for rule changes.
Does NGFW firewall slow down network?
Modern NGFWs are designed for high performance. Fortinet FG-200F: 20 Gbps throughput, 2.4 Gbps with IPS+AV. Cisco FPR-2130: 10 Gbps throughput, 4.5 Gbps with IPS. During design we match model to your traffic with 30% headroom.
