SMS gateway spoofing is a significant security threat to businesses relying on phone numbers for identity verification, as it allows attackers to manipulate SMS sender IDs to appear legitimate, potentially leading to account takeovers, financial fraud, and loss of customer trust. To combat this, adopting a multi-channel approach for OTP delivery, such as using WhatsApp, Viber, or voice calls, alongside SMS, is crucial to prevent interception. Advanced risk assessment tools should be employed to analyze phone numbers for fraud indicators like disposability or being virtual (VoIP), and businesses should continuously monitor and adapt their verification processes to counter new spoofing techniques.

This system allows businesses to tailor their security measures to their specific risk profiles and compliance needs, while also providing a user-friendly experience through its developer-first approach and seamless integration capabilities.
