Overview
The Reality Defender detection platform analyzes media to identify AI-generated audio, video, and images. Reported customers include financial institutions using the platform for fraud detection, government agencies, and media organizations. The company is among a small number of deepfake detectors marketed to enterprise customers; other commercial detection services include Sensity, Hive and Truepic (Synthetic Media / Deepfakes).
In an October 2024 announcement the company described its customers as financial entities, government agencies and media conglomerates, and said it had detected millions of deepfakes, prevented voice fraud in real time and deflected state-sponsored attackers since launching in 2021. It described its product as a cloud-based web platform and API using a patented multi-model approach (Source: prnewswire.com).
Reality Defender's approach is detection after content has been created, in contrast to provenance approaches such as C2PA and SynthID, which label content at the time of generation. These two approaches address synthetic-media identification at different points: provenance at generation time and detection after the fact. In a July 2026 post, Colman described the company as "detection-only," stating that it does not replace identity systems, does not depend on watermarking, and does not rely on generation platforms to police themselves (Source: realitydefender.com).
Products
At its October 2023 Series A announcement the company offered detection across audio, video, images and text, launched an "Explainable AI" feature that color-codes paragraphs of AI-generated text for text-detection clients, and introduced real-time voice deepfake detection for select clients such as call centers and anti-fraud teams (Source: prnewswire.com). By July 2026 the company described its platform as detecting AI-generated voice, video and images in real time, delivered through APIs and within contact centers, meetings, onboarding flows, hiring pipelines and investigations (Source: realitydefender.com).
