Web Application Firewall (WAF) reviews by real, verified users. Find unbiased ratings on user satisfaction, features, and price based on the most reviews available anywhere.
Web application firewalls (WAF) are designed to protect web apps by filtering and monitoring incoming traffic. These tools analyze HTTP traffic as it comes in, blocking potentially malicious traffic and identifying traffic anomalies. Companies use these tools in conjunction with additional application security software to better protect operational web applications. These tools differ from traditional firewalls, which control traffic between servers, by filtering traffic and content attempting to access a specific web-based application.
To qualify for inclusion in the Web Application Firewalls (WAF) category, a product must:

WAF software products are used to protect web applications and websites from threats or attacks. The firewall monitors traffic between users, applications, and other internet sources. They're effective in defending against cross-site forgery, cross-site scripting (XSS attacks), SQL injection, DDoS attacks, and many other kinds of attacks.
These software solutions provide automatic defense and allow administrative control over rule sets and customization since some applications may have unique traffic trends, zero-day threats, or web application vulnerabilities. These tools also provide logging features to document and analyze attacks, incidents, and normal application behaviors.
Companies with web applications should use WAF tools to ensure all weak spots in the application itself are filled. Without WAF, many threats may go undetected, and data leakage may occur. They have truly become an obligatory component of any business-critical web application containing sensitive information.
Key Benefits of Web Application Firewall (WAF) Software
There are a variety of benefits associated with WAF tools and ways they can boost security of applications deployed online. Most of the reasoning behind WAF usage is the generally accepted belief that web-based threats should be a concern for all businesses. Therefore, all businesses deploying web-based applications should be sure they are doing all they can to defend against the myriad cyberthreats that exist today.
Some of the numerous threats WAF products can help defend against include:
The actual individuals using application firewalls are software developers and security professionals. The developer will typically build and implement the firewall, while it is maintained and monitored by security operations teams. Still, there are a few industries that may be more inclined to use WAF tools for various purposes.
Internet Businesses — Internet businesses are a natural fit for WAF tools. They often have one or multiple public-facing web applications and various internal web apps for employee use. Both of these kinds of applications should be guarded by some kind of firewall, as well as additional layers of security. While nearly all modern businesses use web applications in some capacity, internet-centric businesses are more susceptible to attacks simply because they likely possess more web apps.
E-Commerce Professionals — E-commerce professionals and e-commerce businesses that build their own online tools should be using WAF technology. Many e-commerce applications are managed by some kind of SaaS provider, but custom-built tools are incredibly vulnerable without an application firewall. E-commerce businesses who fail to protect their applications put the data of their visitors, customers, and business on the line.
Compliant-Required Industries — Industries that require a higher level of compliance for data security should use a web application firewall for any application that communicates with a server or network with access to sensitive information. The most common business types with increased compliance requirements include health care, insurance, and energy industries. But many countries and localities have expanded IT compliance requirements across industries to prevent data breaches and the release of sensitive information.
Some WAF products may be geared toward specific applications, but most share a similar set of core security features and capabilities. The following are a handful of common features to look for when considering the adoption of WAF tools.
Logging and Reporting — Provides required reports to manage the business. Provides adequate logging to troubleshoot and support auditing.
Issue Tracking — Tracks security issues as they arise and manages various aspects of the mitigation process.
Security Monitoring — Detects anomalies in functionality, user accessibility, traffic flows, and tampering.
Reporting and Analytics — Provides documentation and analytical capabilities for data gathered by the WAF product.
Application-Layer Control — Gives user-configurable WAF rules, such as application control requests, management protocols, and authentication policies, to increase security.
Traffic Control — Limits access to suspicious visitors and monitors for traffic spikes to prevent overloads like DDoS attacks.
Network Control — Lets users provision networks, deliver content, balance loads, and manage traffic.
