Reken Unveils On-Device AI Fraud Shield for Businesses

A new startup named Reken has emerged from two years of stealth development. The company aims to combat security threats in the AI era with its on-device AI security platform. Reken's founder, Shuman Ghosemajumder, previously built systems at Google to prevent click fraud and founded Shape Security, which F5 acquired for $1 billion. His new venture focuses on what he calls the "collapse of trust in online communication." Reken's platform, called the Reken Private Core, uses small, proprietary AI models that run directly on a user's device. This differs from many competitors who send data to cloud-based services, which can introduce data breach risks and time lags. The first product from this platform is Northstar, a phishing-and-fraud defense tool. Ghosemajumder states that Northstar provides just-in-time AI to detect threats that humans might miss, offering an alternative to traditional corporate security training. This technology could change how businesses protect against sophisticated online fraud.
