Stopping voice-based fraud before it starts.

Financial institutions and credit card companies are increasingly targeted by AI-generated voice phishing — also known as vishing. VishProof is being developed to meet this evolving threat with precision, realism, and security-first thinking.

We are currently focused on:

Simulating advanced vishing attacks to help organizations understand how attackers exploit voice channels
Training teams and auditing workflows using adversarial audio crafted to mimic real-world fraud attempts
Building the foundation for future real-time detection tools through our internal research on speech manipulation and spoofing signals

Acoustic Framework

What’s Next:

The ACOUSTIC Framework

We’re developing ACOUSTIC — a modular simulation engine designed to manipulate and detect spoofed speech. This will allow banks, call centers, and security teams to:

Stress-test voice authentication systems
Train staff with realistic, AI-powered voice attacks
Explore the limits of current anti-vishing defenses

ACOUSTIC is currently in R&D and will launch to select partners as part of our early access program.
