Lori Beer

Lori Beer's team recently wrote an open letter to third-party suppliers, asking them to step up their efforts on security and compliance. The letter mentioned concentration risk, a growing concern to bank regulators as banks gravitate toward the cloud-based services of tech behemoths like Google, Microsoft and Amazon. 

One antidote to concentration risk that her bank, JPMorganChase, has embraced is working with smaller vendors.

"Engaging with smaller providers is definitely important," said Beer, who is global chief information officer at the $4 trillion-assets bank, the country's largest. "We actually have a team dedicated to helping us ensure that we are engaging with emerging tech companies in addition to the big hyperscalers."
