Fraud can be complex because it's not just a business problem, nor an technology problem, not an operational problem either. It's a combination of all.

From business side, to start with, business models and processes need to be designed with fraud and risk mitigation in mind; good business measurements and analytics need to be in place to measure the true cost of fraud; conscious decisions need to be made to balance fraud losses and friction to business and cost of implementation.

Fighting fraud utilizes lots of data, fast. Availability, scalability, and performance of the technology platform are demanded. Sifting through large scale of data to generate insights as well as to predict likelihood of bad actors can be challenging.

No risk platforms exist without manual reviews. Case management and operations not only keep the automated risk engine honest, but improves customer experience in case of false positives.

I've learned many things about fraud and risk the hard way. But they don't have to be hard. One of the unfortunate facts is that fraud fighters don't communicate or share knowledge or help each other enough. This is why I am starting a place to share, to collaborate, and, eventually, to win over fraudsters together.
