Comprehensive suite simplifies configuration while frequent updates require management

Mainly, it comes with the complete suite of Microsoft services. I can use it in conjunction with the best options and other features that come with it. Configuration is much easier than using different platforms. For example, if I have hosted the application in AWS and am using the Application Firewall from Azure, there are certain additional steps to follow when configuring them. With Microsoft, everything is within a single suite, making it easier to configure and plan. Azure continually upgrades platforms and sends us messages to upgrade to the next version, simplifying the process. Later, it's much easier if I want to upgrade the software platform, scale it, or move it to a different application host as the whole suite comes together. The return on investment is good. If I am doing applications for clients, I can invoice them for better costs. Most applications that I run and use have a better return on investment.

"It's great for protecting against DDoS attacks."

"It's quite a stable product and works well with Microsoft products."

"It has been a stable product in my experience."

"The most valuable feature of Azure Web Application Firewall is its ability to filter requests and block false positives by using custom rules and the OWASP rule set."
