7 Web Application Firewall to Compare for Securing Your Business

Thousands of website get hacked every day.

While scanning for vulnerabilities is often a priority, most companies do not have time and resources to repair them. According to the Osterman Research Survey Report 2016, 71% of SMEs have suffered a security breach during the previous 12 months.

Whether you’re a solopreneur, an IT manager, a director of security, an established business owner, a CTO, or something in between, it is critical to understand the risks and secure them proactively.

Web application firewall is a viable option to secure web application layer and here are the some of the best options to compare.

1. Incapsula WAF

Imperva’s cloud-based web application firewall is one of the most popular options to secure Layer 7. It secures web applications from all kinds of application-layer attacks, including OWASP Top 10.

Incapsula works on flexible scripting language and supports even custom rules for more advanced attacks. Imperva WAF comes under the Website Security product suite, which also offers bot mitigation and backdoor shell protection.

Notably, Imperva’s Incapsula also offers other services including Content Delivery Network (CDN), Load Balancer and Distributed Denial of Service (DDoS) Protection. The combination of these services is apt for small and big companies to secure their business online.

2. Sucuri Website Firewall

When it comes to web firewall comparison list, Sucuri Website Firewall is a serious contender. It offers protection from hackers trying to exploit OWASP Top 10 vulnerabilities including SQLi, XSS, and CSRF.

It also includes mitigation of the Distribution Denial of Service (DDoS) attacks backed by continuous monitoring. Sucuri Website Firewall intercepts and inspects all incoming HTTP/HTTPS requests site.

Although it does not offer custom rules, it has fast response policy for zero-day vulnerabilities. As and when the vulnerability is made public, Sucuri engineers patch your environment to block attacks trying to exploit that vulnerability.

3. Indusface TAS

Indusface Total Application Security combines scanning, web application firewall, and monitoring services in one solution. It detects application layer threats, including OWASP Top 10 and zero-day vulnerabilities and protects against exploits.

Real-time monitoring also secure web applications from DDoS attacks.

Their Total Application Security, which includes WAF, is available On-Premise, As A Service and through the AWS Marketplace.

What makes it useful for small and big businesses is that WAF not only patches vulnerabilities with web application scanning sync but it also monitors hacker activities on the application to learn new attack patterns and ways to detect and protect against them.

4. CloudFlare WAF

When it comes to web application firewall comparison, Cloudflare’s collective intelligence is a useful feature to look onto. Other than OWASP Top 10 protection and custom rules, this WAF considers pushing custom rules to all clients, if required. This essentially means that your website gets security intelligence from other sites too.

This essentially means that your website gets security intelligence from other sites too.

The company monitors the internet for new types of vulnerabilities and their engineers study each one to understand what custom rule will best solve the problem.

Cloudflare claims to be powering a million domains and hence having a lot of data on security intelligence and how it can affect the business or/and its customers.


Just like with other services of Amazon Web Services (AWS), pay only for what you use for their WAF. It blocks all the common Layer 7 attacks that compromise security or application availability.

Additionally, AWS’ firewall can be deployed either on Application Load Balancer (ALB) or Amazon CloudFront.

The benefits of this WAF include traffic filtering (based on IP addresses, HTTP headers, HTTP body, or URI strings), AWS cloud integration and support, and virtually real-time analytics.

AWS WAF is an ideal solution for individuals and businesses who’d like to manage their WAF within the AWS Management Console.

6. Akamai WAF

Akamai’s Kona Web Application Firewall reduces the risk of data theft, downtime, and other security breaches. It’s real-time monitoring also provides visibility into security events so that the administrators can take actions accordingly.

It offers protection from the most common web-based attacks that exploit Injection, Cross Site Scripting, and malicious file execution. However, DDoS protection is not bundled with WAF and is available as an additional service.

Akamai also offers a myriad of other website performance solutions that includes Content Delivery Network (CDN), Web and Mobile Acceleration, and Traffic Management.

7. Qualys WAF

Qualys’ Web Application Firewall combines scalability and manageability within its suite of products. This cloud solution not only offers protection from OWASP exploitations but can also be managed under one console that also supports their web application scanning and virtual machines.
