Next-Generation Firewalls (NGFWs) are a critical component of any organisation's cybersecurity strategy. In 2023, we saw several new developments in the NGFW market, as vendors continue to innovate to meet the needs of organisations in the face of increasingly sophisticated cyber threats.

NGFW 2024 trends

One of the most significant trends in the NGFW market is the increased use of artificial intelligence (AI) and machine learning (ML). AI and ML can be used to develop more sophisticated NGFW features, such as the ability to detect and block zero-day attacks, as well as to automate security tasks. For example, some NGFWs now use AI to analyse traffic patterns and identify anomalous behaviour that may indicate a cyber-attack.

Another important trend is enhanced protection against cloud-based threats. As more and more organisations move their data and applications to the cloud, they need NGFWs that can protect them from cloud-based attacks. Many NGFWs now offer features such as cloud security posture management (CSPM) and cloud workload security (CWS) to help organisations protect their cloud environments.

In addition, NGFWs are becoming more flexible and scalable to meet the needs of hybrid and multi-cloud environments. Hybrid and multi-cloud environments combine on-premises and cloud-based resources, which can make them complex and difficult to secure. NGFWs can help organisations secure their hybrid and multi-cloud environments by providing a single point of control for network security.

Finally, NGFWs are now incorporating user behaviour analytics (UBA) capabilities to help organisations detect and respond to insider threats and other suspicious activity. UBA can be used to analyse user behaviour patterns and identify anomalies that may indicate a malicious actor. For example, UBA can be used to identify users who are accessing sensitive data at unusual times or from unusual locations.

These are just a few of the new developments that we saw in the NGFW market in the past year. As cyber threats continue to evolve, we can expect to see even more innovation in the NGFW space in 2024. Organisations that are looking to improve their network security posture should consider NGFWs with the latest features and capabilities.

Next-gen firewall explained

There are many types of malware that a firewall can protect against these days, including ransomware, viruses, worms, trojans, adware, and more. Next-Generation Firewalls take it a step further, by offering the ability to not only identify but also completely block malware before it enters your network. NGFWs can swiftly detect and combat attacks across the entire network. As cyber-attacks continue to become more sophisticated, next-generation firewalls will continue to be essential components of any organisation’s security solution, whether you’re in a data centre, network, or cloud.

Reviewing next-generation firewalls and their capabilities is one of the steps that need to be taken to significantly improve an organisation’s security. Cyberattacks and advanced hacking methodologies these days not only drive enterprises to look for next-generation firewalls, but they also drive next-generation firewall vendors to optimise and update their solutions.

Malicious emails, phishing schemes, and other threats concealed in content can be hard to detect. Luckily, many next-generation firewall vendors offer the threat prevention capabilities IT security staff is looking for. The best firewalls include application awareness, centralised management features, Deep Packet Inspection, 100Gbps threat protection, as well as hybrid cloud security. For example, to help defend against the rise of malware, intrusion attempts bypass perimeter protection and other advanced threats.

Next-generation capabilities have been achieved by all solutions in the enterprise network firewall market, but vendors differentiate on feature strengths and depth. NGFW should be on every company's shortlist. - Mohamed El Haddouchi, CTO, Nomios

NGFW solution features to look for

Most NGFW solutions providers offer different types of firewalls; physical, virtual and containerised firewalls. Physical firewalls are available for all types of organisations, ranging from small and midsized enterprise campuses to large enterprise data centres and everything in between. Virtual firewalls provide protection in Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, IBM Cloud, and Oracle Cloud environments. Container firewalls offer security services to improve visibility and secure applications running in containers and microservices. Depending on your situation, there is always an NGFW that will fit your needs. Next, it is smart to look at the different features that firewalls offer.

Features offered by the best NGFWs solutions include IDS/IPS, support for single-enterprise firewalls as well as branch offices, web proxy and URL filtering, Web Application Firewalling and virtual versions that can be deployed within the cloud.

For an NGFW solution comparison, it’s crucial to look for differences in the:

  • Performance;
  • Third-party security product integration capabilities;
  • Ease of installation and use;
  • Effectiveness at blocking threats;
  • Additional features such as application visibility and cloud protection;
  • And of course: pricing and consumption models.

Here are our picks for the 5 best solutions for NGFW in 2024

Palo Alto Networks NGFW

Palo Alto was recognised by Forrester as the Leader for Enterprise Firewalls in the Forrester Wave in Q4 2022. And by Gartner® they have been named a Leader for elenth consecutive years in its Magic Quadrant™ for Network Firewalls. We expect that in 2024 Gartner and Forrester will publish new research on the best NGFWs.

Palo Alto Networks Next-Generation Firewalls consist of physical appliances (PA-series), virtualised firewalls (VM-series) and container firewalls (CN-series). They are all based on a consistent single-pass architecture and inspect all traffic, including all applications, threats, and content, and tie that traffic to the user, regardless of location or device type. They can secure multi-cloud businesses with their cloud identity engine and protect organisations from the SaaS explosion with an integrated CASB. Palo Alto has brought the power of inline machine learning to their cloud-delivered security services, where they established threat coverage in DNS security, web protection from unknown threats in advanced URL filtering and real-time protection with WildFire malware analysis.

In 2022 Palo Alto announced that they have teamed up with Amazon Web Services (AWS) to unveil their new Cloud NGFW for AWS. In August 2023 they launched the Cloud NGFW for Azure. A managed NGFW running as an Azure-native ISV service. This service is designed to streamline and simplify operations while strengthening security for customers running on Microsoft Azure.
