Polygraf AI Meeting Guard Detects Deepfakes in Video Calls

Polygraf AI launches Meeting Guard to detect deepfakes, impersonation, AI-generated responses, and PII exposure during enterprise video meetings.

AI security company Polygraf AI has launched Meeting Guard, a real-time fraud-detection tool that joins virtual meetings as a visible participant and monitors for deepfake voices, AI-generated responses, identity impersonation, and sensitive-data exposure.

The platform is designed for enterprise and government users across Zoom, Microsoft Teams, and Google Meet.

According to Polygraf AI, the new solution is designed to combat AI-powered attacks during virtual meetings and video calls.

The company cited the reported rise in AI-assisted hiring fraud, deepfake executive impersonation, live exposure of PII, and nation-state infiltration attempts targeting enterprises worldwide.

“Every meeting is now a security event,” said Yagub Rahimov, chief executive officer at Polygraf AI.

“AI has fundamentally broken the trust model organizations relied on for remote communication. The ability to verify identity through a face, voice, or conversation is no longer enough.”

In its official press release, Polygraf AI said organizations face an estimated annual exposure ranging from $2.5 million to more than $71.4 million due to AI-enabled meeting fraud. According to the company, this includes executive impersonation, hiring fraud, vendor impersonation, and financial scams.

The company also cited Gartner research showing that 62% of organizations have experienced a deepfake attack, including 37% involving video calls and 43% involving audio calls. Gartner also predicts that one in four candidate profiles worldwide will be fake by 2028.

To address these risks, Polygraf AI said it designed Meeting Guard as an all-in-one solution to help protect organizations against AI-enabled fraud, impersonation, and synthetic identity threats.

It requires no integrations and operates only during meetings, unlike traditional fraud-prevention and video verification tools, according to Polygraf AI. The solution is powered by the company’s AI Behavioral Control Plane, which combines deepfake voice detection, AI-generated response flagging, live PII detection, audio redaction, and compliance audit trails to identify suspicious behavior and sensitive data exposure in real time.

Meeting Guard is compatible with major video conferencing platforms , including Zoom, Google Meet, and Microsoft Teams.

The solution is built on an encrypted SOC 2 Type II- and ISO 27001-certified infrastructure and operates under a strict no-training policy.

In addition, the company stated that standard cloud deployment can be completed in under 15 minutes, while hybrid and on-premises rollouts are typically completed within 1 to 2 weeks, with dedicated white-glove onboarding support.

Built for enterprise and government environments, Meeting Guard functions as both a secure compliance assistant and an AI notetaker.

It detects AI-generated content, verifies voices against deepfake threats, flags potential PII leaks, and generates meeting notes and summaries without transmitting data to external services.

In practice, Meeting Guard joins virtual meetings as a visible participant and provides real-time security analysis to attendees throughout the session.

For channel partners, Meeting Guard creates a new opportunity for a security and compliance service around virtual collaboration.

MSPs and MSSPs could incorporate the platform into their managed security , identity verification, compliance monitoring, and executive protection offerings, while systems integrators could support hybrid or on-premises deployments for customers with stricter data governance requirements.

The product may also help partners expand conversations deepfake risk beyond email and endpoint security to include hiring, vendor communications, financial approvals, and executive meetings.
