Getting Started

Welcome to JERC Sentry, the real-time telephony security platform designed to protect vulnerable individuals from voice-based scams and fraud. Unlike traditional call blockers, JERC Sentry acts as a proactive network-level intermediary that analyzes calls in real-time and empowers caregivers to intervene when threats are detected.

How It Works: The 4-Step Shield​

JERC Sentry provides a multi-layered defense strategy that operates entirely in the background:

  1. Intercept: Unknown calls are automatically routed through our secure Telnyx-powered backbone using Conditional Call Forwarding (CCF).
  2. Analyze: Our AI pipeline (powered by Deepgram and Groq) converts speech to text and analyzes the conversation context for social engineering patterns (e.g., manufactured urgency, financial requests).
  3. Warn: If a threat is detected, the Protectee hears a private "whisper" warning, and the Protector receives a high-priority push notification.
  4. Intervene: The Protector can review the AI's reasoning in the mobile app and choose to Join the Call or Terminate it remotely.
