In 2025, Yamagata Railway lost approximately ¥100M to bank impersonation fraud

20 Years of Trust, Destroyed in 2 Minutes
In 2025, voice phishing targeting Japanese SMEs has surged. Yamagata Railway lost approximately ¥100M, six Fukuoka Bank clients lost ¥80M combined, and Ryukyu Bank saw single-victim losses of ¥50M.
Attackers use AI to clone voices of bank staff and business partners. Just 3 seconds of audio is enough to generate a convincing fake. By the time you realize "your usual contact" was fake, the money is gone.
SMEs without dedicated security teams need quiet, reliable protection.
Four Layers of VoiceShield Defense
AI Voice Detection
Machine learning detects synthetic and recorded voices. Identifies subtle differences between human and AI-generated speech in real-time.
Final judgment is human. VoiceShield only flags suspicious patterns.
Caller Authentication
Voice biometric matching for registered partners and bank contacts. Quietly verifies if it's really "your usual contact."
Authentication assists. Contract and transfer authority follows existing rules.
Pattern Alerts
Real-time detection of fraud-typical keywords and speech patterns: "urgent," "confidential," "transfer immediately."
Alerts are advisory. Response follows company policy.
Employee Training
Integrates with KODA Training for simulated vishing exercises. Build practical response skills through realistic attack scenarios.
Evaluation and HR implications are organizational decisions.
How VoiceShield Protects You

"This is XX Bank. A security issue has been detected." Automated voice directs to fake site. VoiceShield detects the automated voice pattern and displays warning during the call.
AI-Cloned Partner Request
AI-replicated voice of a regular business partner requests urgent transfer. Voice biometric matching detects the mismatch.
Executive Impersonation
Phone call mimicking the CEO's voice gives direct instructions to accounting. VoiceShield detects synthetic voice characteristics, triggers multi-person verification flow.
