Viettel, Vietnam's leading telecommunications and technology company, and Shush Inc., a global innovator in carrier-grade identity and network authentication, have successfully conducted a Proof of Concept (PoC) to evaluate the application of network-based authentication capabilities using the Sherlock platform. The PoC focused on leveraging the trust and reputation of mobile network-assigned IP addresses through the implementation of the CAMARA Number Verification API, positioning it as an alternative to traditional OTP-based SMS authentication.

Why it matters

In the context of increasingly sophisticated cyber threats, identity fraud, and account takeover, this collaboration represents an important initial step toward the deployment of a passwordless authentication model, helping to reduce fraud while enhancing user experience, in line with Vietnam's digital identity development strategy and fintech ecosystem orientation.

The details

As part of the PoC, Viettel and Shush jointly deployed and integrated the Sherlock platform with Open Gateway - Viettel's centralized Network API enablement platform. Sherlock is a network authentication platform developed by Shush, serving as a logical processing layer that aggregates and transforms native network APIs into standardized Network APIs compliant with GSMA Open Gateway and CAMARA standards, without requiring invasive changes to a carrier's infrastructure.

  • The PoC was successfully conducted in January 2026.
