Learn what Next Generation Firewall is and what its advantages are

With the increasing sophistication of cyber threats, the need for more advanced security solutions, such as the Next Generation Firewall, becomes evident. For instance, according to research by Check Point Research, cyberattacks in Brazil increased by 38% in the first quarter of 2024.

In this context, the Next Generation Firewall (NGFW) emerges as an evolution of traditional firewalls, bringing more robust and efficient features to protect corporate networks and data.

In this article, you will understand what a Next Generation Firewall is, its functions, and the advantages of adopting this technology in your organization. Read on!

What is a Next Generation Firewall? A Next Generation Firewall is a network security solution that goes beyond the capabilities of traditional firewalls. While conventional firewalls focus on packet filtering based on predefined rules and controlling traffic between internal and external networks, NGFWs incorporate a range of additional functionalities that provide more comprehensive protection.

Here’s what a Next Generation Firewall does:

• Deep Packet Inspection (DPI): Unlike traditional firewalls, which only analyze packet headers, NGFWs perform deep inspection, examining the full content of packets, allowing for the detection and blocking of sophisticated threats like malware and exploits.
• Application Control: NGFWs identify and control the use of applications within the network, regardless of the port or protocol used. This means specific security policies can be applied to different applications, ensuring that only permitted ones can be executed.
• Intrusion Prevention System (IPS): Integrated with the NGFW, the intrusion prevention system monitors the network for suspicious activities and attempts to exploit vulnerabilities, blocking them before they can cause harm.
• Content Filtering: NGFWs provide advanced content filtering capabilities, blocking access to malicious websites, inappropriate or unwanted content, and preventing downloads of dangerous files.
• Secure VPNs: In addition to providing robust protection within the network, NGFWs also support the creation of virtual private networks (VPNs), enabling secure and encrypted connections for remote users.

What are the benefits of adopting a Next Generation Firewall? Adopting a Next Generation Firewall brings several significant benefits for an organization’s cybersecurity. Here are some key advantages:

• Enhanced Threat Protection: With the combination of deep packet inspection, application control, and intrusion prevention, NGFWs offer a much more robust layer of security. They can detect and mitigate threats that would go unnoticed by traditional firewalls, reducing the risk of cyberattacks.
• Visibility and Control: NGFWs provide complete visibility into network traffic, enabling IT administrators to monitor and control application usage and user activities. This visibility is crucial for identifying anomalous behavior and responding quickly to security incidents.
• Reduced Complexity: By integrating various security functionalities into a single solution, NGFWs simplify the security infrastructure, reducing the complexity of managing multiple devices and lowering operational and maintenance costs.
• Adaptability and Scalability: NGFWs are designed to adapt to the specific needs of each organization, easily scaling to meet network growth and new security demands, ensuring continuous protection without compromising performance.
• Compliance Support: Adopting an NGFW can help organizations comply with security standards and regulations, such as the LGPD. The ability to monitor, log, and report network activities facilitates compliance demonstration and the implementation of security policies required by the regulation.

In conclusion, in a landscape where cyber threats are rapidly evolving, having an advanced security solution is essential. The Next Generation Firewall is a key component in terms of protection, offering functionalities that go beyond simple packet filtering. With the ability to deeply inspect data, control applications, prevent intrusions, and much more, NGFWs are a strategic choice for any organization looking to ensure the security of its network and data.
