Online fraud and abuse poses a serious risk to all digital businesses and having preventive measure in place has become indispensable.

In this talk we will be looking at how to build a Symfony application tasked with detecting and preventing malicious activities such as credit card fraud, automated registrations and abuse of free resources.
Our application will collect data from different sources and provide a RESTFul API to other services to guide access to resources, trigger verification requests and block suspicious activities.
