Each month, The ThreatMetrix Global Trust Intelligence Network (The Network) screens more than 500 million site visitors, across more than 1,900 customers and 9,000 websites and uses predictive analytics to differentiate between legitimate and fraudulent behavior, personas and devices.
In a recent snapshot from May 1 through July 31, 2013, The Network found that the average online bank account is accessed by 2.4 unique devices. The data was compiled across a diverse set of industries – including banking, e-commerce, enterprise, insurance, social networks, government and healthcare – and found that bank accounts are accessed by a significantly higher number of unique devices than other industries.
In July 2013, data shows that 55 percent of bank accounts are accessed by one device, 26 percent are accessed by two devices, 11 percent are accessed by three devices, and 4 percent are accessed by four devices. While there is a significant drop-off after four devices, the data shows a very small percentage of accounts being accessed by as many as twenty devices in a one-month period, which raises some red flags.
