Best Next-Gen Firewalls 2022

Firewalls play a crucial role in cybersecurity architectures all over the world. With an increasing amount of data being generated each day and evolving threats to enterprise security, defending data and applications is becoming more difficult. Firewalls are virtual barriers that secure enterprise networks from hackers, malware, and other forms of attack.

Firewalls come in the form of both software and hardware and provide consolidated security between enterprise networks and outside threats. Next-generation firewalls (NGFWs) are the third generation of firewall technology.

Benefits of Next-Gen Firewalls

NGFWs cover all the services that traditional firewall technologies like unified threat management (UTM) and web application firewalls (WAF) have to offer. In addition, they provide advanced threat protection, intrusion prevention systems (IPS), deep-packet inspection (DPI), and layer 7 application control technologies.

IT administrators configure NGFWs to specific system requirements to make sure that no data is vulnerable. Once a NGFW is implemented, they oversee firewall tools to ensure security. NGFWs can be deployed in four methods: public cloud, private cloud, on-premises (edge) and on-premises (internal).

The benefits of NGFWs include:

• Creating virtual barriers between enterprise networks and the internet.
• User access filtering and assessment.
• Alerting IT managers when unauthorized access is attempted.
• Outlining and enforcing security and authentication rules.
• Automating tasks associated with monitoring or testing.

When considering NGFW vendors and products, look for these features:

• Application and user identity awareness
• Centralized management, visibility and auditing
• Dynamic packet filtering
• Deep-packet inspection
• Intrusion prevention systems
• Network sandboxing
• HTTPS, SSL/TLS and encrypted traffic
• Threat intelligence feeds and dynamic lists
• Integration capacity

In this guide, we will dive into all you should know about the top products and service providers in the NGFW sphere.

Top Enterprise Next-Gen Firewall Providers

Here are the best next-gen firewall vendors.

Huawei

Huawei’s HiSecEngine USG6600E Series AI Firewall (fixed-configuration) is designed for medium- and large-sized enterprises and next-gen data centers. HiSecEngine USG6600E Series AI Firewall provides NGFW capabilities and cooperates with other security devices to dynamically defend against enterprise network threats, resolve performance deterioration issues, and enhance border detection capabilities.

USG6600E firewall provides Internet Protocol Security (IPsec) services, security detection and encryption/decryption service processing acceleration and pattern matching capabilities.

Key Differentiators

• Provides real-time intelligent threat processing at the network edge. The device can defend against vulnerability-based attacks, like Structured Query Language (SQL) injections and cross-site scripting (XSS) attacks.
• Offers simplified operations and maintenance (O&M) based on change policies and service deployment, significantly reducing operating expenses.
•  Provides several integrated protection capabilities, including uniform resource locator (URL) filtering, anti-spam functions, distributed denial-of-service (DDoS) attack protection, bandwidth management, data leak prevention, a virtual private network (VPN), intrusion prevention and antivirus.
• Identifies more than 6,000 applications and combines application identification with data filtering, antivirus and intrusion detection, thereby improving detection accuracy and performance.
• Manages per-user and per-internet protocol (IP) bandwidth by managing policy-based routing (PBR), ensuring the minimum bandwidth, limiting the maximum bandwidth and changing application forwarding priorities.
• Coordinates with the local or cloud sandbox to detect and block harmful files.

Fortinet

Fortinet’s FortiGate 7121F Series (hardware) delivers high-performance NGFW capabilities for large-sized enterprises. With high-throughput, high-port density and multiple high-speed interfaces, ideal deployments are at the network edge, across internal segments and the hybrid data center core. The NGFW provides advanced threat protection, IPS and SSL inspection to optimize your network’s performance. FortiGate 7121F Series is the only NGFW that offers 400G connectivity.

Key Differentiators

• Actively identifies thousands of applications inside network traffic for granular policy enforcement and deep inspection.
• Protects against malware, malicious websites and other forms of attack in both encrypted and unencrypted traffic.
• Fortinet’s AI-powered, real-time threat intelligence detects and prevents known and unknown attacks.
• Delivers ultra-low latency and sublime threat protection performance using purpose-built Security Processing Unit (SPU) technology.
• Offers multi-tenancy, extensive deployment flexibility and effective utilization of network resources.
• Includes a simple and effective management console that provides network automation and visibility.
• Provides full user, device and application visibility across the entire attack surface.  

Palo Alto Networks

Palo Alto Networks’ ML-powered virtual NGFW, VM-Series Virtual NGFW, adopts complete zero trust network security. The VM-Series Virtual NGFW flexibly scales to secure deployments in SDN environments, public clouds and private clouds. The NGFW is easy-to-deploy, automatable, scalable and helps isolate and safeguard critical systems. The VM-Series Virtual NGFW helps you watch over software-defined agility and cloud speed.   

Key Differentiators 

• Consistently protects against advanced threats in real time, with full control and traffic visibility. Secures development and multi-cloud environments with the same extent of protection as on-premises data centers.
