Web Application Firewall
A web application firewall is a system that intercepts all the traffic to your web application and filters out bad HTTP traffic, thereby protecting the web application from hackers and other bad actors.
As most of the businesses are moving online, hacking web applications has become a growing black market industry. You must have heard about several data breaches that have happened in the recent past. There is a separate section on data breaches in the new General Data Protection Regulation (GDPR) that the European Union (EU) has made enforceable from 25th May 2018. In such circumstances, it has become critical to protect your web applications as much as possible.
Even though web application firewalls were available for past few years, they typically cost thousands of US dollars in upfront as well as recurring costs. Also, installing and managing a web application firewall is a complicated affair. You need experienced system admins to ensure the correctness of the configuration and continuous availability of the web application firewall on your custom provisioned hardware.
