Fremont, CA: The next-generation firewall (NGFW) market is undergoing significant transformation due to machine learning and artificial intelligence integration into networking and security features. These technologies can delve deeper into network traffic, necessitating vendors and IT teams to stay updated on the evolving threat landscape and complex enterprise environments. Here are a few influential trends to watch.
The Internet as a Corporate Network (And the Associated Risks)

Enterprises rely on the Internet as a corporate network, but it's unreliable, opaque, and insecure. Uptime is impossible, threats are prevalent, and IT staff has limited visibility. Network Guards (NGFWs) are crucial in protecting against internet-based attacks. They constantly gather threat information from various sources to maintain security. Vendors are adding advanced network traffic analysis, such as signature-based intrusion detection and application-specific packet inspection, to their NGFWs.
Enterprise Wan Edges
Enterprises are transitioning from traditional hub-and-spoke models to a new Enterprise WAN edge, enabling branches to access cloud services where cable/DSL is unavailable. This shift is driven by remote work and the expansion of IoT devices across vertical markets. Software Defined Wide Area Networks (SD-WAN) enable direct traffic routing from branch locations to trusted cloud applications, simplifying security deployment across network edges.
Increasingly Treacherous Threats
The threat environment in networks has become increasingly sophisticated, with cybercriminals using advanced persistent cybercrime tactics and upgrading old-school botnets. Ransomware, particularly Ransomware-as-a-Service (RaaS), is a growing concern, with 67% of organizations reporting a ransomware attack and nearly half being targeted to multiple times. To address this, a converged approach to networking and security is crucial. New Generation Wired Firewalls (NGFWs) should integrate with other security solutions like Zero Trust Network Access (ZTNA) and inline sandboxes to protect against emerging threats. Future NGFWs will rely on AI and ML technology to predict advanced threats before they occur.
Rise of the Hybrid Mesh Firewall
Hybrid mesh firewall platforms enable IT teams to define and enforce policy controls across workloads, users, and locations, making them essential for managing complex, hybrid environments. This capability will grow in importance as organizations contend with work-from-anywhere environments. When selecting NGFWs, IT teams should ensure seamless communication and integration with each other, whether in the cloud, on-premises, or virtual machines. This will help organizations manage their IT environments effectively.
