NGFW vs Traditional Firewall

Hello everybody! In this article I compare next generation firewall and traditional firewall.

Firewalls have long been the cornerstone of network security, serving as the first line of defense against cyber threats. Over the years, firewall technology has evolved significantly, with Next-Generation Firewalls (NGFW) emerging as a game-changing advancement. In this article, we will compare NGFW and traditional firewalls based on key parameters to help you make an informed decision when choosing the right firewall for your organization.

Parameters of Comparison

1. Application Visibility and Application Control:

• Traditional Firewall: Offers partial visibility into applications and limited control.
• Next-Gen Firewall (NGFW): Provides detailed insights into applications and offers granular control over them. NGFWs can identify and control applications at Layer 7, making them highly effective in managing network traffic.

2. CAPEX and OPEX:

• Traditional Firewall: Typically incurs higher capital (CAPEX) and operational (OPEX) costs since organizations need to purchase and maintain multiple devices for various security services.
• Next-Gen Firewall (NGFW): Offers a considerable reduction in costs as it bundles multiple services into a single device. This consolidation not only reduces upfront expenses but also simplifies ongoing maintenance.

3. IPS (Intrusion Prevention System):

• Traditional Firewall: Does not support an Intrusion Prevention System.
• Next-Gen Firewall (NGFW): Supports IPS, enhancing security by actively monitoring and preventing intrusion attempts.

4.NAT (Network Address Translation):

• Traditional Firewall: Supports NAT, enabling the translation of private IP addresses to public ones.
• Next-Gen Firewall (NGFW): Also supports NAT, ensuring compatibility with existing network configurations.

5.Reputation and Identity Services:

• Traditional Firewall: Does not support reputation and identity services.
• Next-Gen Firewall (NGFW): Provides robust reputation and identity services, which are crucial for advanced threat detection and user authentication.

6.Traffic Filtering (Port, IP Address, and Protocol-based):

• Traditional Firewall: Supports basic traffic filtering based on ports, IP addresses, and protocols.
• Next-Gen Firewall (NGFW): Offers the same traffic filtering capabilities but adds advanced application-level awareness for more precise control.

7.VPN (Virtual Private Network):

• Traditional Firewall: Supports VPN functionality for secure remote access.
• Next-Gen Firewall (NGFW): Also supports VPN, ensuring secure communication over public networks.

8.Application Level Awareness:

• Traditional Firewall: Lacks application-level awareness.
• Next-Gen Firewall (NGFW): Excels in application-level awareness, allowing for fine-grained control over applications and their behaviors.

9.Working Layer:

• Traditional Firewall: Operates from Layer 2 to Layer 4 of the OSI model.
• Next-Gen Firewall (NGFW): Functions from Layer 2 up to Layer 7, making it capable of deep packet inspection and application-level decision-making.

10.Throughput and Performance:

• Traditional Firewall: Offers lower throughput and may experience significant performance degradation when additional security services are introduced.
• Next-Gen Firewall (NGFW): Provides much higher throughput compared to traditional firewalls and maintains consistent performance even with additional security services enabled.

11.Reporting:

• Traditional Firewall: Typically offers standard reports.
• Next-Gen Firewall (NGFW): Provides customized reporting options, allowing organizations to generate reports tailored to user-level requirements. It also offers near real-time details and supports various download formats.

In conclusion, Next-Generation Firewalls (NGFWs) outshine traditional firewalls in various aspects, including application visibility, cost-effectiveness, security features, and performance. NGFWs are designed to meet the demands of modern networks, where application-level control, threat prevention, and efficient management are paramount. When choosing between NGFW and a traditional firewall, it’s essential to consider your organization’s specific requirements and the level of security and control needed to protect your network effectively.
