Mark Nelsen

SVP Risk & Authentication Products
Visa

Mark Nelsen is Senior Vice President at Visa Inc. where he is responsible for leading Visa’s global Risk and Authentication Products organization whose teams deliver solutions across fraud risk, credit risk, and authentication. In this role, his focus spans across new technology, new product development, core product management, and product optimization often including sophisticated solutions serving merchants, acquirers and client financial institutions. Mark’s team also delivers Visa Advanced Authorization (VAA), which is the fraud scoring engine that analyzes up to 500 data elements of every Visa-processed transaction to determine the risk of fraud. Since it was launched just over a decade ago, VAA has grown increasingly effective at spotting the tiny percentage of suspicious transactions from the roughly 150 million payments that flow through the Visa network each day. Prior to joining Visa, Mark was a senior architect at IBM Global Services, where he managed large-scale e-business application development for global companies. Mark holds a B.S. degree in Industrial Engineering from the University of Wisconsin.
