About Reality Defender
Reality Defender provides deepfake detection to stop AI-generated media from causing harm. It sells to enterprises, platforms, and institutions, including financial services, government, insurance, healthcare payers, and legal teams. The company offers tools that analyse audio, video, and images in live calls, meetings, and uploaded files. Its detection can be embedded into existing systems, giving an independent signal that clients use to verify, route, or block content according to their own rules. The company differentiates itself through an ensemble of models that are blended, tested, and updated to catch a wide range of synthetic media. It provides real-time detection and enterprise-grade scale, with turnkey integrations for everyday applications and advanced options for sensitive environments. Deployment can be on-premises, in private cloud, containerised, or on secure air-gapped laptops. Reality Defender also offers an API and SDKs for developers to add detection to their own apps.
