Next Generation Firewall (NGFW)

What is Next Generation Firewall (NGFW)?

The next generation firewall (NGFW) is the first line of defense against today’s threats and is a critical component of any defense-in-depth strategy. The NGFW market is one of the largest and most mature in the cybersecurity industry. NGFW technologies have evolved from packet filtering and circuit-level gateways to application layer (proxy-based) and dynamic packet filtering firewalls that use port and protocol combinations to create and enforce access control policy between trusted and untrusted networks.

Traditional FWs relied on common application ports to determine which applications were running and which attacks to watch for, but the NGFW can identify and allow, block, or limit applications regardless of the ports and protocols used.

NGFW must also be capable of performing deep packet inspection on all packets, on all ports, and over all protocols in order to determine which applications are running over which ports and thus secure them effectively. Also, the expanded use of SSL/TLS in much of the traffic traversing the modern network makes it necessary to inspect encrypted content.

What We Tested

NSS Labs' Next Generation Firewall (NGFW) Group Test evaluates market-leading NGFW products on security effectiveness, performance, stability and reliability, and total cost of ownership (TCO). The NGFW Group Test provides individual Test Reports and Comparative Reports that enable enterprises to make informed decisions to evolve and rationalize their cyber risk programs.

What You Get
NGFW Product Test Reports

Security Comparative Report

The Security Comparative Report provides high-level analysis of the security effectiveness of different NGFW products in the market. The report provides comparisons of firewall policy enforcement, intrusion prevention capabilities, and resistance to common evasion techniques.

Using this report, enterprise security teams can compare security effectiveness and resistance to evasion techniques across different NGFW products.

Example Report

Performance Comparative Report

The Performance Comparative Report provides analysis of various performance metrics for tested NGFW products. The report contains comparisons of UDP throughput latency, maximum capacity, HTTP capacity, and HTTP capacity with persistent connections.

Using the Performance Comparative Report, enterprise networking teams can compare performance across NGFW products and select those products that will support their volume and type of network traffic.

Example Report

Total Cost of Ownership (TCO) Comparative Report

The TCO Comparative Report provides a comparison of the costs associated with product purchase, installation, maintenance, and support, as well as threat-associated costs.

Using the TCO Comparative Report, the enterprise C-Suite and management can understand the true TCO of a product over a three-year period, incorporating product purchase cost, product operational cost, and the overall capability score of a product.

Example Report

Security Value MapTM (SVM) Comparative Report

Empirical data from individual Test Reports and Comparative Reports is used to create NSS Labs' unique Security Value Map (SVM). The SVM illustrates the relative value of security investments by mapping the Security Effectiveness and the Total Cost of Ownership (TCO) per Mbps of tested product configurations.

The SVM Comparative Report provides an aggregated view of the detailed findings from the NSS Labs group tests. Using this report, enterprise security decision makers can see the relative value of security investments.

Example Report

Individual Test Reports

Test Reports provide detailed analysis for each product tested. Data from these reports is used in the NSS Labs Comparative Reports.

Test Reports enable enterprise security teams to understand the impact of features and limitations across different products. These reports are used to shortlist products for further evaluation and proof-of concept testing.
