Leading payment gateway provider in North America with significant market share among small to medium-sized businesses
Authorize.net is a payment gateway service provider that enables merchants to accept credit card and electronic check payments through their websites and retail stores. Founded in 1996, it is one of the oldest and most established payment gateway providers in the United States. While not strictly an AdTech company, Authorize.net operates in the broader digital commerce infrastructure space, providing the payment processing backbone that enables e-commerce transactions, including those driven by digital advertising and marketing campaigns. As a subsidiary of Visa Inc. (acquired in 2010 through Visa's purchase of CyberSource), Authorize.net serves hundreds of thousands of merchants and processes billions of dollars in transactions annually. The platform offers a comprehensive suite of payment management tools, fraud detection services, and recurring billing capabilities. Its role in the digital ecosystem is foundational rather than advertising-specific, though it enables the monetization of online businesses that rely on digital advertising for customer acquisition.
