At Plivo, protecting your SMS communications is a top priority. To help shield your applications and business from fraudulent SMS activity, we offer multiple layers of fraud protection designed to reduce risk and keep your costs under control. Here’s an overview of the key features we provide to safeguard you from SMS fraud:
1. Geo Permission Feature
Our Geo Permission feature lets you restrict SMS traffic to specific countries. By setting messaging thresholds, you can limit the number of messages sent to a country and automatically block any excess traffic. This helps prevent fraudulent messaging attempts targeting regions you don’t serve, while also avoiding unexpected charges caused by unauthorized use.
2. Fraud Shield for Verify
Fraud Shield protects your Verify applications from SMS pumping attacks by continuously analyzing both current and historical SMS traffic patterns. It detects anomalies in destination countries, carriers, and number sequences that may indicate artificially inflated or suspicious traffic. By combining these insights with known fraud patterns, Fraud Shield proactively blocks potentially harmful messages before they reach your users—helping you avoid unexpected charges and reduce the risk of abuse.
3. SMS Pumping Protection via SMS API
Our SMS Pumping Protection feature automatically detects and blocks suspicious messages sent through the SMS API. By analyzing both current and historical SMS traffic, the system identifies unusual spikes or known fraudulent behavior. When suspicious activity is detected, messages to associated phone numbers are blocked immediately, preventing fraud before it impacts your service.
While our fraud protection features significantly reduce the risk of SMS pumping and related attacks, no system can guarantee 100% protection. For the strongest defense, we encourage all customers to implement robust security practices within their applications.
Our fraud protection tools are designed to safeguard your business and complement your own security efforts. Please note these measures do not alter your responsibilities under Plivo’s Terms of Service.
