Account takeover fraud (ATF) is a growing problem, with an estimated 22% of American adults experiencing it. The trend has been driven by the expansion of online financial services, which are predicted to grow to $310 billion. ATF can lead to significant losses for victims and damage companies' reputations. Strategies to combat this issue include using machine learning at the edge to analyze large amounts of data quickly, improving AI/ML algorithms to reduce false positives, and real-time ingestion of customer, market, and transactional data from multiple sources. Aerospike's real-time data platform offers these capabilities while maintaining high reliability and low total cost of ownership.
