web application firewall types: which one to choose?

The Web Application Firewall (WAF) of your website/web application functions as a force field by screening and stopping malicious requests and botnets. In addition to the “OWASP Top 10” list of the most common attacks, a WAF protects your web applications from a wide variety of threats.  There exist several Web application firewall types. XSS and SQL Injection (SQLi), for example, are safeguarded. Your web applications’ incoming traffic is screened for potentially harmful requests and banned or filtered accordingly. As a result, you can ensure that your online apps are secure.

Web application firewall types

Hardware-based WAF

A hardware-based WAF is installed near the web and application servers on the local area network (LAN). Software settings and updates are possible thanks to the appliance’s operating system. A hardware-based WAF is the best option in terms of speed and performance. The device’s proximity to the server enables fast data monitoring and filtering.  There is a significant expense to purchasing and maintaining hardware devices, which is the most critical disadvantage. It is more costly to buy, install, store, and maintain hardware-based WAFs than any other kind of WAF. Hardware-based Web Application Firewalls (WAFs) are often used by large organizations that get hundreds of thousands of visits each day. Thus, speed and performance are given high priority to serve many clients at once correctly.  Furthermore, the administrative and maintenance costs of maintaining and managing hardware are easily affordable by most prominent corporations. Unlike other WAFs (load balancing), a hardware-based WAF containing an application delivery controller is WAPPLES. While most of its competitors employ signature-based detection systems, WAPPLES uses a proprietary COCEPTM engine with rule-based detection algorithms as its primary detection method. Rules-based detection makes it one of the most effective WAFs, and this not only speeds up delivery but also improves application performance.

Software-based firewall for web applications.

A WAF running in a virtual machine (VM) replaces a physical appliance. All of the WAF components are included in a hardware WAF. The only difference is that one. To use the virtual computer, each user would need their hypervisor. Hardware-based WAFs are more like going to a coffee shop to get your morning java, while software-based WAFs are more like going to a drive-thru. If you’re looking for something that can be tailored to your organization’s requirements, a software-based WAF is your best bet. As well as being able to connect to cloud-based servers, the virtual machine may be deployed in the cloud and linked to on-premises systems. Software WAFs are also less expensive than hardware WAFs. Compared to a hardware WAF, the monitoring and filtering process takes longer in a virtual environment. For example, data centers and hosting firms use software WAFs to safeguard their cloud-based web and application servers. Small and medium-sized organizations (SMEs) often utilize them to protect their web applications since they are less expensive. We think the ideal present would be the following: Whipping cream is an essential component of many desserts. In terms of capabilities and features, WAF WAPPLES SA (software appliance) is identical to WAPPLES when it comes to software. Both KVM and XenServer may run virtual machines on top of the operating system. Consequently, it may be utilized on AWS, Google Cloud, Microsoft Azure, and VMWare-based public and private cloud servers.

Cloud-based firewall for web applications

The term “SaaS” refers to cloud-based WAFs managed by a service provider. This is a relatively new development in WAF technology (software-as-a-service). There is no need to install anything on the user’s end since the WAF components are all hosted in the cloud rather than deployed locally or in virtual machines. The most significant advantage is that it’s straightforward. To make use of the service, all needed is a monthly membership. There is no need for the user to be concerned about optimization and upgrading since the service provider handles these tasks. However, there is minimal room for modification because the service provider takes the WAF. Cloud-based WAFs are great for small and medium-sized enterprises since they don’t need a lot of extra resources to maintain. The product Cloudbric comes highly recommended. One of the most advanced DDoS prevention and content delivery network (CDN) services may be found in Cloudbric, a piece of software. Cloudbric’s security and maintenance services are easy to use no matter where the app is hosted.

Choosing a Web Application Firewall: What to Consider?

Finding the proper Web Application Firewall from several Web application firewall types, even after knowing all there is to know about WAFs, still proves to be a struggle. This is owing to the extensive range of WAFs available on the market, each having its own unique set of features and issues as an explanation. As a consequence, the front and running costs of each are different. So, what exactly are we going to do? What should I look for while making my decision on a WAF? It would be best if you conferred with your operational and technical teams, as well as the service provider, to choose the best WAF for your firm (vendor). These questions will help you better understand your requirements and the product’s characteristics that can help you satisfy those needs.
