SentryPeer is an innovative and efficient fraud detection solution that helps users safeguard their phone calls against malicious activities. By tracking and recording the IP address and number of bad actors attempting to make phone calls, SentryPeer creates a comprehensive database of fraudulent activities. With this information, users can generate notifications and take preventive measures to stop future fraudulent activity before it happens.

Furthermore, the tool offers a user-friendly interface that enables users to easily access a list of collected phone numbers and generate notifications before expensive calls are made or worse happens. SentryPeer's advanced technology ensures that users have complete ownership and control over their collected data, which is shared via peer-to-peer methods. With SentryPeer, users can rest assured that their phone calls are secure and protected against fraudulent activities.
