What Is a Next-Generation Firewall?
A Next-Generation Firewall (NGFW) combines traditional firewall capabilities with additional security and visibility controls. Instead of relying only on source and destination IP addresses and ports, an NGFW can provide deeper awareness of applications, users, content and threats, depending on the platform and licensed capabilities. CODE3 supplies and configures next-generation firewalls for businesses across Dubai and the UAE.
NGFW Assessment, Architecture, Installation & Configuration
A firewall should fit into the network architecture rather than simply sit at the internet edge.
Reviewing the current firewall and network architecture to identify configuration gaps and opportunities.

- Restrict risky or file-sharing applications
- Limit access to specific users
- Control applications on non-standard ports
Inspecting traffic for known attack patterns and other suspicious activity.
- Exploit attempts & network attacks
- Vulnerability exploitation

- Malware & phishing categories
- Newly registered & suspicious domains
- Command-and-control destinations
- Social, streaming & file-sharing categories
DNS Security, Malware Protection & SSL/TLS Inspection
SSL/TLS inspection should not be enabled blindly across every traffic category; exclusions and certificates need to be planned carefully.
Monitoring or controlling access to suspicious and malicious domains.
- Malicious & phishing domains
- Command-and-control domains
- Suspicious DNS activity
- Complements endpoint & email controls
Inspecting network traffic and files for supported malware indicators.

User-Based & Device-Aware Security Policies
User-based and device-aware policies provide greater context than IP-only rules when the platform and identity integration support them.
Applying policies to users or groups rather than only IP addresses.
- IT administrators & finance users
- HR & management
- Guest users & contractors
- Specific security groups
Incorporating device information into policy decisions where supported.
- Device type & operating system

Security controls extending beyond the physical office firewall.
- Microsoft Azure & AWS
- Hybrid environments
- Cloud-native networking & security groups
- Routing, identity & workload architecture
NGFW & Zero Trust
An NGFW alone does not constitute a complete Zero Trust architecture — it contributes as one layer among several.
Firewall Logging, Monitoring & Rule Optimization
The objective is to make rules easier to understand, maintain and audit while preserving required business connectivity.
Reviewing logs that provide valuable information about network activity.
- Allowed & blocked traffic
- Security events & VPN activity
- Application traffic & web requests
- Integration with SIEM/SOC where appropriate
Ongoing support after installation.

Common Firewall Problems We Solve
Real issues we investigate and resolve in existing firewall environments.
Security inspection, VPN and SSL inspection can affect performance. We review traffic patterns, services, capacity and configuration.
Large rulebases become difficult to understand. We review rules, objects, NAT and unused policies.
Failures can result from authentication, routing or encryption issues. We review tunnel configuration, routing and authentication.
An application may depend on specific ports, protocols or inspection behavior. We identify traffic requirements and review policies.
Port-based rules may lack application-level visibility. We use application-control and user-based policies.
HTTPS can conceal malicious content from basic inspection. We evaluate SSL/TLS inspection requirements and exclusions.
Poor naming and years of additions create complexity. We conduct a structured rule and configuration review.
