Having a rule-based detection system not only makes it much easier to update, but also maximizes delivery speed and application performance, making it one of the most efficient WAFs in the industry. Unlike most competitors who rely on a signature-based detection system, WAPPLES runs on a patented COCEP TM engine that relies on rule-based detection algorithms. WAPPLES is a hardware-based WAF that comes with an application delivery controller (load balancer), saving the hassle of purchasing them separately. Besides, most large businesses can easily afford the management and operating costs of running hardware. This is because to serve this massive amount of clients efficiently, speed and performance become the highest priority. From acquisition and installation to storage and maintenance, hardware-based WAFs are associated with higher costs compared to other types of WAFs.Ī hardware-based WAF is commonly used by large organizations who gain hundreds of thousands of visits on a daily basis. The major downside is that owning and maintaining hardware machines is not cheap. Due to its physical proximity to the server, it tracks and filters data packets to and from the website with very low latency. The greatest advantage of a hardware-based WAF is fast speed and high performance. An operating system runs within the appliance, supporting software configurations and updates. Hardware-Based Web Application FirewallĪ hardware-based WAF is deployed through a hardware appliance, installed locally within the local area network (LAN) close to the web and application servers. Three types of web application firewalls (WAF)ġ.
Now assuming that we are all familiar with what a WAF does and why every organization needs one (if not, see this article: Why Do I Need a Web Application Firewall? ), let’s now take a look at the types of WAFs available in the market. The figure below shows a simple illustration. Let’s first refresh our minds by taking a quick look at how a web application is hosted and where the WAF is located within the network. Different forms of WAFs have their own advantages and disadvantages, thus it is important to understand their differences before making a well-informed decision. There are plenty of web application firewalls (WAF) offered in the market.
