What happened
Polygraf AI launched (July 14, 2026) Meeting Guard, which joins Zoom/Teams/Meet calls as a visible participant to detect AI-generated content, verify voices against deepfake threats, flag live PII exposure, and generate compliance-ready meeting notes without transmitting data externally.
Why it matters
Addresses a documented, escalating enterprise risk (62% of orgs report experiencing a deepfake attack per Gartner) with a no-integration, real-time in-meeting control rather than post-hoc forensic analysis — notable as executive/vendor impersonation via AI voice cloning becomes a mainstream fraud vector.
Applicability
Enterprises and government bodies concerned about executive impersonation, hiring fraud, or nation-state infiltration via video calls should pilot; particularly relevant for finance, critical infrastructure, and government sectors.
