For anyone interested, Associated Bank (mentioned in the article) is using Fiserv's Corillian [1] product.
The U.S. financial ecosystem is quite different than others around the world. Despite the asset base being consolidated heavily with a handful of institutions, there are still over 11,000 banks and credit unions around the country. Of those 11,000, I would estimate that less than 5% have any significant in house engineering teams (and that is a generous estimate). The rest rely entirely on third parties to run the technology and software that makes a bank a bank. The market is dominated by Fiserv, FIS and Jack Henry & Associates as the article mentions, but there is also a long tail of providers.
Very few bank and credit union executives understand the basics of cybersecurity. The vast majority of CEOs come from some type of lending centric leadership position since that has been the main source of revenue traditionally.
Unabashed plug: If you know a credit union or bank that is need of a better digital banking experience, I would greatly appreciate the plug/intro for Narmi.
