Reality Defender

Reality Defender is a cybersecurity company specializing in the detection of AI-generated synthetic media, commonly known as deepfakes. The company develops multimodal detection technology designed to identify manipulated or artificially generated audio, video, and image content across enterprise environments. Reality Defender's core platform employs an "ensemble-of-models" approach, combining multiple detection models to improve accuracy and leverage diverse datasets for continuous improvement. This architecture is designed to address deepfake fraud across high-stakes enterprise verticals, including financial services, where AI-driven impersonation represents an active and growing threat. The company offers several products and developer tools under its "Real Suite" umbrella, including a publicly accessible Deepfake Detection API (RealAPI) and an SDK. These tools are designed to allow developers and enterprises to integrate deepfake detection capabilities into their own applications with minimal coding effort. Reality Defender's target market includes enterprise organizations and financial institutions. The company has been recognized by JPMorganChase's 2025 Hall of Innovation for its work defending organizations against AI-driven impersonation and fraud. It has also participated in NATO's Cognitive Warfare Experimentation, indicating engagement with government and defense sectors. In December 2025, Gartner named Reality Defender the front-runner in deepfake detection, particularly within high-stakes enterprise verticals, citing its capital position, global distribution network, and multimodal AI platform as key differentiators.
