Charm Security partners with Reality Defender to add deepfake detection to AI workforce for fraud prevention

Charm Security has partnered with Reality Defender to integrate deepfake detection capabilities into Charm's agentic AI workforce for fraud prevention. The collaboration enables financial institutions and enterprises to access real-time deepfake detection for voice, image and text through Charm's AI agents. The integration allows Charm's agents to directly invoke Reality Defender's technology to assess whether communications are authentic or manipulated, eliminating the need for teams to switch tools. This builds on Charm's Psychology-First Fraud Agents, which use the company's Human Vulnerabilities & Exploits model to provide insight into human intent and deception. Both Charm and Reality Defender are RSAC Innovation Sandbox companies, with Reality Defender winning the 2024 award. The partnership aims to help organisations respond to deepfake-enabled fraud more quickly whilst maintaining human context in security workflows.
