Video calls used to be one of the few places you could be sure you were talking to a real person — deepfake voice and video tools have quietly ended that certainty. Polygraf AI's Meeting Guard sits in on your Zoom, Teams or Google Meet calls like an extra silent participant, watching for signs that someone (or something) isn't who they claim to be.
Polygraf AI is an AI security company building on-premise, zero-trust detection for deepfakes and synthetic content. Its Meeting Guard product monitors live meetings for deepfake voices, AI-generated responses, identity impersonation and PII exposure using a proprietary 'AI Behavioral Control Plane', with local/on-premise deployment so meeting data never leaves the customer's network. Polygraf also offers Vexon Voice Detector (deepfake/phishing audio detection) and an AI Content Detector that fingerprints text against ChatGPT, Gemini, Claude and open-source model outputs. The company targets both enterprise and government/defense customers, with SCIF-ready, IL2–IL6 compliant deployment options.
💬 Our review
The short version: Polygraf AI is built for organizations worried about deepfake fraud in high-stakes meetings — think finance, legal or government calls where impersonation could mean real financial or security damage, not everyday team standups.
Its differentiation from generic AI-detection tools (GPTZero, Originality.ai, which mostly check written text) is the real-time, in-meeting angle plus a local-deployment option for regulated environments — the SCIF-ready, IL2-IL6 positioning signals this is aimed squarely at defense/government and large enterprise, not small teams. Being named 'Most Innovative Cybersecurity Company' by The Hacker News is a real, checkable credential, which adds confidence. The downside is that pricing is entirely opaque (no self-serve tier, sales-only), and the product's own homepage is aggressively firewalled against automated access — reasonable for a security company, but it also means a smaller business can't quickly self-serve a trial the way it could with a lighter competitor. Budget for an enterprise sales cycle, not a credit-card signup.
