Underdog Case Study
The fourth most downloaded sports gaming app in the U.S. sets a new standard in the industry during high volume NFL season

Underdog partners with Socure for global bank-level security for KYC controls Now the fourth most downloaded sports gaming app in the U.S., Underdog implemented Know your Customer (KYC) controls that exceed industry standards, unsurpassed by the other large operators in the sector For online gaming platforms, high volume periods like the NFL season can bring a rise in fraudulent activity.
This can look like bonus hunters creating multiple accounts to take advantage of promotions, to more serious scenarios such as identity theft or the use of synthetic identities to establish valid accounts on the platform. These platforms also contend with attempts to obtain unauthorized access to players’ accounts through phishing, keylogging, and credential stuffing.
In a highly competitive environment, a seamless user experience is paramount — especially when it comes to onboarding and depositing or withdrawing funds. Players want instant options that give them the quickest outcome without any extra hurdles or friction.
Underdog, now the fourth most downloaded sports gaming app in the U.S., was challenged by the manual review processes that led to long waiting times for players.
It needed a strategic partner to help balance automation and manual intervention, and create global-bank level security for its KYC controls — all so it can onboard more good users faster.
Challenges
• Attempted fraudulent activities ranging from bonus hunters to identity theft
• Account takeover attempts through phishing, keylogging, and credential stuffing
• Attempted friendly fraud • Manual review processes
leading to longer waiting times for players and resources to handle the volume
Solution highlights
• Partnered with Socure to implement advanced KYC processes, risk models, and document verification
• Developed proprietary fraud models complemented by Socure’s services
Results
• Established “global bank- level” security for KYC that exceeds industry standards
• Reduced false positives in fraud detection
• Balanced automation with expert human intervention
• Improved efficiency in handling high-traffic periods like the NFL season
• Strengthened overall platform integrity and player safety
The challenge Like most in the industry, the most common fraud Underdog experienced was friendly fraud. Where third-party fraud involves using a cardholder’s information without their consent, friendly fraud involves the actual cardholder or someone within that household (hence family fraud) making a transaction and then disputing it later.
During the prior NFL season, the Underdog team was forced to manually review far too many accounts, which resulted in longer waiting times for its players — and additional headcount to handle the volume.
To address these challenges, Underdog leverages internal and third- party data and analytics to provide the best experience to its player base, built on a solid risk framework and guided by evolving models and recommendations.
“Data plays a crucial role as it provides us with undisputable, irrefutable hard evidence. Every decision that Underdog makes is based on data,” said Karl Gambin, VP of Fraud and Payments. “We tend to stay away from old- fashioned models of doing business and strive to be innovative and unique, which is very evident in our product offering.”
During peak season, Underdog is constantly monitoring the efficiency and effectiveness of its proprietary fraud models in addition to third-party provided services, including its partnership with Socure.
How Socure helped Underdog continually analyzes logic in relation to observed patterns and makes changes as the season progresses.
