Next Generation Firewall (NGFW)

High threat protection performance with automated visibility to stop attacks

Next-Generation Firewall Overview

 

Tmexexpert next-generation firewalls (NGFWs) utilize purpose-built security processors and threat intelligence security services from AI-powered Tmexexpert labs to deliver top-rated protection, high performance inspection of clear-texted and encrypted traffic. Next-generation firewalls reduce cost and complexity with full visibility into applications, users and networks and provides best of breed security. As an integral part of the Tmexexpert  Security Fabric next-generation firewalls can communicate within Tmexexpert comprehensive security portfolio as well as third-party security solutions in a multi-vendor environment to share threat intelligence and improve security posture.

As enterprises consider how to provide comprehensive visibility and advanced layer 7 security, including threat protection, intrusion prevention, web filtering and application control, they face a major complexity hurdle managing these point products with no integration and lack of visibility. Gartner estimates that by 2019 80% of enterprise traffic will be encrypted and 50% of attacks targeting enterprise will be hidden in encrypted traffic to infiltrate networks or exfiltrate data, therefore employing HTTPS inspection is a requisite.

Next-Generation Firewall Use Cases

 

Reducing complexity by consolidating products to save costs is a top concern for many enterprises. Equally important is ensuring secure access of resources from private and public clouds without the fear of encrypted malware. Achieving granular visibility of devices, users, real-time threat information, and automation are paramount to ensuring that attacks are handled in a timely manner.

Benefits of Next-Generation Firewalls

Multi-functional

 

Traditional firewalls provide basic packet filtering, network and port address translations, stateful inspections, and can even support virtual private networks. However, they are only limited to the Data Link Layer and Transport Layer of the OSI model.

 

In addition to all the functionalities of traditional firewalls, next-generation firewalls also include integrated intrusion detection systems (IDS) and intrusion protection systems (IPS) that detect attacks based on traffic behavioral analysis, threat signatures or anomalous activity. This functionality helps perform deeper inspection and improve packet-content filtering of network traffic up to the application layer.

Application awareness

 

Traditional firewalls typically block common application ports or services on a network to control application access and monitor specific threats. However, with network connectivity becoming more complex, several applications use multiple or various ports, making it extremely difficult for traditional firewalls to identify the targeted port.

 

Moreover, these ports are being used in various other ways such as tunneling, in which a network protocol is enclosed within the packets carried by the second network and is de-encapsulated at the destination.To counter this, next-generation firewall devices monitor traffic from layer 2 through layer 7 and are intelligent enough to determine what exactly is being sent or received. If the content is within policy, it is sent further or else it’s blocked.

 

Application awareness also enables companies to set policies depending on the user and the application. For instance, allowing users to access Facebook, but blocking Facebook Chats.

Threat protection

 

Unlike traditional firewalls, NGFWs include antivirus and malware protection that’s continuously upgraded automatically whenever new threats are discovered. The NGFW device also minimizes the avenues of attack by limiting the applications that run on it.

 

It then scans all the approved applications for any hidden vulnerabilities or confidential data leaks, as well as mitigates risks from any unknown applications. This also helps in reducing bandwidth usage from any useless traffic, which isn’t possible with traditional firewalls.

Network speed

 

Though many vendors of traditional firewalls claim to offer a specific throughput (usually a gigabyte) from every port, the reality is entirely different.

The increased number of protection devices and services, when turned on, tend to choke the network speed. By the time the traffic reaches the end user, the speed is chopped by almost one-third of the actual promised speed.

In contrast, next-gen firewall throughput remains exactly the same irrespective of the number of protection services.
