This case study explains how Crassula.io, a digital banking platform provider, enhanced its verification and authentication processes by integrating Telesign’s SMS API. As digital banking expanded, Crassula faced increasing fraud risks from unverified users and synthetic identities. Telesign’s SMS one-time passcode (OTP) verification became the primary method for authenticating actions such as registration, logins, and transactions. This strengthened Crassula’s security posture, reduced exposure to fraudulent activity, and optimized user verification. The solution improved attack management, minimized costs from fraud, and reinforced customer trust through seamless, secure onboarding.
