Sumitomo mitsui banking corporation secures retail banking services

Sumitomo Mitsui Banking Corporation (SMBC), one of the world’s largest banks, faced a sharp rise in cybercrime—phishing, man-in-the-middle and man-in-the-browser attacks—that threatened its retail Internet banking. Seeking an easy-to-use, future-proof authentication method that could be shared with affiliate financial companies and replace TAN lists, SMBC evaluated options and selected OneSpan’s Digipass 275.

OneSpan implemented Digipass 275 as a portable, design-oriented two-factor authentication token (with Digipass Plus for multi-identity support), replacing TAN lists and integrating strong 2FA into SMBC’s security infrastructure. The rollout let SMBC distribute Digipass devices free at branches, protect customers from advanced fraud schemes, enable scalable affiliate adoption, and deliver a cost-effective, future-ready solution that strengthened customer confidence.
