Next-generation firewalls can recognize applications independent of port, protocol, evasive tactics, or SSL encryption and provide real-time protection against a wide range of threats, including those at the application layer.
Fremont, CA: Next-generation firewalls (NGFWs) comprise deep-packet inspection firewalls that add application-level inspection, intrusion prevention, and intelligence from outside the firewall to a port/protocol inspection and blocking. They are a more sophisticated variant of standard firewalls. A next-generation firewall (NGFW) should not get mistaken for a standalone network intrusion prevention system (IPS), which comprises a commodity or non-enterprise firewall, or a firewall and IPS in the same device are not tightly linked.

Next-generation firewalls can recognize applications independent of port, protocol, evasive tactics, or SSL encryption and provide real-time protection against a wide range of threats, including those at the application layer. This increases security since users can identify the exact programs operating on port 80 by looking at the application rather than simply the port. Furthermore, they can prevent program usage and functionality by detecting them.
Some of the advantages of Next Generation Firewalls:
It is multifunctional.
Next-generation firewalls include integrated intrusion detection systems (IDS) and intrusion prevention systems (IPS) that identify assaults based on behavioral traffic analysis, threat signatures, or unusual activity, in addition to all of the features of classic firewalls. This feature aids in performing deeper network traffic inspection and improving packet-content filtering up to the application layer.
User Identification and Visibility
NGFWs may associate IP addresses with individual user identities, allowing for per-user visibility and control of network behavior. This provides insight into who is accountable for every application, content, & threat traffic upon that network.
Identification of the Content
With thorough, real-time traffic inspection, NGFWs may scan content to prevent data leaks and block attacks. Threat prevention, URL filtering, and file and data filtering are part of this content identification.
Threat Defense and Mitigation
NGFWs, unlike traditional firewalls, contain antivirus and malware protection that is automatically updated anytime new threats are found. The NGFW device further reduces attack vectors by restricting the programs that run on it.
It then examines all permitted apps for hidden vulnerabilities or personal data breaches and hazards posed by unknown applications. This also aids in lowering bandwidth utilization from unnecessary traffic, which traditional firewalls cannot do.
Advanced Policy Control
Traditional firewalls operate on a straightforward deny/allow model. In this scenario, everyone has access to a good application, but nobody has access to a poor application. This model is just no longer viable. In today's world, an application detrimental to one organization may be excellent for another. Granular degrees of control are provided by NGFWs, allowing the beneficial features of an application to be accessible by the proper personnel while restricting all access to the harmful components of an application.
