Control Risk Exposure With Vonage Fraud Defender

This article was updated on June 23, 2025

Cybercrime is steadily rising, and illicit tactics are rapidly evolving. As fraudsters adapt their strategies, staying ahead of the latest fraud trends needs to be a top priority for businesses. Fortunately, cybercriminals aren't the only ones with increasingly sophisticated technology — fraud detection and prevention tools are also getting smarter. With Vonage Fraud Defender, you can easily implement real-time monitoring, alerting, and notifications to help stop suspicious activity in its tracks for SMS and voice (including Verify 2FA) traffic.
