Step 01
📞
Suspicious Call Detected
The older adult receives or is in the middle of a suspicious call — no action required yet.
Step 02
➕
Add to Conference
The user adds the VivaGuard number to the call via the phone's native "add call" feature. No app. No config.
Step 03
🔇
Silent Entry
The agent joins silently. Two short beeps (500ms, 800Hz) signal presence to the protected user — invisible to the fraudster.
Step 04
👁️
Active Listening
Real-time analysis of every word, tone and pattern. The agent stays completely silent — it does not speak, does not identify itself.
Step 05
🛡️
Calibrated Intervention
When the risk score exceeds the configured threshold, the agent intervenes with the exact message matched to the detected risk level.
Step 06
