How IllumaSHIELD™ Voice Security works
As a caller speaks, IllumaSHIELD™ analyzes unique voice characteristics and other signals in real time to verify identity and identify potential fraud risk. Trusted interactions remain frictionless, while higher-risk interactions can trigger adaptive verification and real-time alerts. Watch the video to see IllumaSHIELD™ Voice Security in action.
Voice Security for the Age of AI
AI-generated voices, deepfakes, social engineering, and account takeover attacks are changing the risks organizations face across the voice channel.
Traditional caller authentication methods such as security questions, PINs, passwords, passphrases, and knowledge-based authentication (KBA) rely on information fraudsters can increasingly obtain or manipulate.
IllumaSHIELD™ Voice Security helps organizations move beyond what callers know to better understand who is calling and whether the interaction presents potential risk.
What Is Voice Security?
Voice Security is a layered approach to protecting voice interactions by combining caller authentication, fraud detection, deepfake defense, adaptive MFA, and real-time risk intelligence.
IllumaSHIELD™ brings these capabilities together in a unified Voice Security platform designed to help organizations establish trust across voice interactions.
Move Beyond Traditional Caller Authentication
Security questions and knowledge-based authentication rely on information fraudsters can increasingly obtain through data breaches, social media, phishing, and social engineering.
IllumaSHIELD™ uses passive voice authentication to help verify trusted callers based on who they are rather than what they know—reducing reliance on security questions while providing additional fraud intelligence when an interaction presents potential risk.
Protect Against AI Voice Fraud, Deepfakes, and Voice Cloning
Generative AI is making voice cloning and synthetic speech increasingly accessible, creating new risks across the voice channel.
IllumaSHIELD™ combines passive voice authentication, AI fraud detection, deepfake detection, adaptive MFA, and real-time risk intelligence to help organizations protect against AI-generated voice fraud, deepfakes, voice cloning, account takeover, caller impersonation, and social engineering.
Voice authentication helps establish who is calling, while fraud and deepfake detection provide additional intelligence about whether the interaction may present risk.
