Any company that creates online revenue, must have a Risk and Fraud team.
Even with machine learning implementation, you need the human sector to oversee that everything works flawlessly.
Also, depending on the sector you work in, you have to adhere to the laws of the regions you service or sell to.
Be flexible with working hours and schedules.
Risk and fraud does not happen between 9 am and 5 pm. It happens 24/7.
A good plan is to break up the working day for your risk team.
3 or so hours in the day and more hours in the late afternoon or evening.
This will allow all the fraudulent payment attempts to be caught before they even hit your back ends.
You don’t hire people to do them a favor!
You hire them to help your company succeed and grow.
