Full Tilt Poker is the second largest online poker room; it belongs to Rational FT which is a computer services company that develops software, business computer maintenance and performs operations based digital marketing. Two fundamental points of running a poker room online are the integrity of the site and the trust of customers. Players must be completely sure that they are protected against fraud. Negative publicity on this subject has a direct and immediate impact on customer loyalty, the ability to attract new customers and sales. The difficulty here is the volume of data to process, the complexity of the analysis, the difficulty of detecting all forms of fraud and costs.
