While you make the most of the benefits of digitization, it is also important to protect your business. By investing in a network firewall, you can create a digital barrier. It helps protect your sensitive data while preventing unauthorized access.

However, if you do not take firewalls seriously in 2025, you might face downtimes and data breaches. This can tarnish your business reputation and lead to financial issues.

Network firewalls have been in use for decades, protecting devices and networks from cyber threats. Primarily, its function is to establish a barrier between external actors and the internal network.

Therefore, read on to get a better idea of how network firewalls work and how they might benefit your business.

What Is a Network Firewall?

With the help of a network firewall, you will be able to monitor, inspect, and restrict traffic that moves in and out of your network. However, it is fundamentally different from web application firewalls. The latter deals with HTTPs threats and merely protects applications.

Hence, start investing in network firewalls such as Sangfor Athena Next Generation Firewall NGFW to create a robust network security system. These firewalls will perform real-time traffic monitoring while defending your networks and systems against cyberattacks and unauthorized access. Apart from that, try to utilize the following network firewalls to protect your system from vulnerabilities:

• Packet filtering
• Stateful inspection
• Proxy service
• Network address translation (NAT)

Additionally, your organization may already have established network security policies in place. Hence, once you implement a network firewall in your system, it will analyze the data packets in your network accordingly. Thereby, it will validate those data packets and will protect your network against data breaches.

Furthermore, a network firewall will also protect your network from DDoS attacks. Also, it will alert your network administrators to take immediate action.

Major Features of Network Firewalls That Will Benefit Your Business

To deal with different types of cyber threats, you must develop a strong security framework. It is possible when you protect your network with a firewall. Moreover, ensure your network firewall complies with your network security policies.

The following are some of the major features of network firewalls that you will benefit from:

1. Traffic and Web Filtering

With the help of network firewalls, you can filter and control the flow of traffic. The following are the major criteria behind filtering traffic:

• IP addresses (both source and destination)
• Protocols
• Port numbers

These will help you prevent unauthorized access to your network. This way, you will also be able to block malicious traffic on your network. In addition to that, firewalls help you filter web content. Here, too, you have to set categories and domain names. This way, the network users will not end up on risky websites.

Meanwhile, those firewalls also come with access control features. Hence, with their help, you will be able to enforce access policies on your network. In fact, it allows you to block traffic from particular sources.

2. Intrusion Detection and Prevention

When it comes to modern firewalls, these check traffic through intrusion detection and prevention systems. This way, the firewalls detect suspicious activities and other threats. As a result, you can make your security defenses stronger while dealing with advanced threats.

3. VPN Support

The best network firewall services come with Virtual Private Network (VPN) support. Hence, if you use a VPN to access data and information through your network, you will benefit from data encryption.

Primarily, a VPN encrypts data that your internal network users exchange with remote users. Thereby, the VPN ensures secure remote access. As a result, you will be able to secure your sensitive information when your off-site employees access your network.

4. Safeguard from Malware

Some of the best network firewalls have the feature to scan for malware effectively. This way, they ensure the safety of files, links, and other attachments. Hence, when users download or open them, they will be able to access data safely.

5. High Availability Configurations

High firewall configuration is available with many network firewalls. If you integrate them into your network, you will benefit from uninterrupted operation. In this case, multiple firewalls work together in synchronization.

However, if a firewall fails to work in sync, another takes over easily. This way, there are no service disruptions for your network.

6. Bandwidth Control

Network administrators love to regulate bandwidth usage among users and applications. This is possible through the bandwidth control of network firewalls.

In this case, network administrators regulate the network bandwidth to optimize network performance. They do so by giving more priority to critical applications. Also, to ensure security, they even forego less essential traffic.

7. Application Awareness

If you use advanced network firewalls, you will be able to implement application-based security policies. Here, the firewalls will recognize the existing applications in your network. This way, it will tailor your network security policies according to different applications. Hence, you will have better control of all your applications in the network.

8. Deep Packet Inspection

By investing in a strong network firewall, you will benefit from deep packet inspection (DPI). For example, next-generation firewalls (NGFWs) come with this feature. This helps you analyze the contents of your data packet. Merely analyzing header information is not enough in those cases.

Thereby, you will be able to detect sophisticated application-layer attacks. Hence, it will be easier for you to prevent them with a next-gen firewall. Obviously, this is not possible with traditional firewalls.

Why You Must Choose the Athena Next-Generation Firewall?
