Organizations initially exploring device fingerprinting for fraud prevention often begin with open-source solutions due to their accessibility and speed, which is beneficial for those in growth phases. However, these tools generally offer limited accuracy, leading to significant blind spots that can be exploited by fraudsters, particularly as AI-driven fraud becomes more complex. Open-source solutions often struggle with changes in browser settings or updates, resulting in unrecognized returning devices and increased risks of payment fraud, account takeover, and new account fraud. Fingerprint Pro offers a more robust alternative by using a hybrid architecture that combines raw device signals with sophisticated server-side analysis, achieving an identification accuracy of around 94% during proof-of-concept phases. This approach allows for persistent visitor IDs that remain stable despite environmental changes, supporting a comprehensive view of visitor activity and aiding in the detection of fraud attempts. Fingerprint Pro's server-side processing and Smart Signals provide deep insights into visitor behavior, enhancing fraud detection and prevention. The platform is compliant with major data protection regulations, offering organizations peace of mind regarding privacy and security, while also supporting a more resilient fraud prevention strategy.
