Web Application Firewall (WAF)

What is Web Application Firewall (WAF)?

Attackers have moved up the stack. They are no longer simply attacking the web server and its underlying operating systems; they are attacking the web applications running on the web server that are front-ending critical corporate data. Such applications are often incredibly complex and difficult to secure effectively, and simple coding errors can render them wide open to remote exploits. To regain the upper hand against current attacks, enterprises must evolve their network defenses to provide a different kind of protection. Web application firewalls (WAFs) exist in order to prevent web servers and their applications from being exploited.

What We Tested

NSS Labs' Web Application Firewall (WAF) Group Test evaluates market-leading WAF products on security effectiveness, performance, stability and reliability, and total cost of ownership (TCO). The WAF 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
WAF Product Test Reports

Security Comparative Report

The Security Comparative Report provides high-level analysis of the security effectiveness of different WAF products in the market. The report provides comparisons of defensive capabilities, stability and reliability, and resistance to common evasion techniques.

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

Example Report

Performance Comparative Report

The Performance Comparative Report provides analysis of various performance metrics for tested WAF products. The report contains comparisons of maximum capacity and HTTP capacity without caching (with and without transaction delays) using real-word traffic mixes.

Using the Performance Comparative Report, enterprise networking teams can compare performance across WAF products and select those 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.
