Shush Inc

Shush Inc is a SaaS company that provides silent network authentication solutions for Mobile Network Operators (MNOs), financial institutions, and CPaaS partners. The company operates as a supply-side platform that bridges the gap between enterprise demand for network-based authentication and the network data held by MNOs. The core product, Shush Sherlock, is a cloud-agnostic SaaS platform built around an API gateway that processes GSMA CAMARA-compliant API requests from enterprise developers, CPaaS partners, and financial institutions. Sherlock connects to MNO network infrastructure to retrieve network attribute data, enabling capabilities such as Silent Authentication, SIM Swap Detection, and Device Status monitoring, along with over 44 additional APIs. The platform also serves as a monetization layer for MNOs, allowing them to set pricing and manage billing for API utilization. Shush's authentication approach is designed to replace traditional OTP-over-SMS methods, which are vulnerable to SIM swap attacks and SMS spoofing. Silent Authentication uses the SIM card and mobile network data to verify user identity without requiring the user to take any action, preserving the mobile app user experience while improving security. The company also offers White-Glove managed services, drawing on telecom industry expertise to integrate Shush Sherlock with MNO network elements and support the business operations required to run a network authentication business unit. These services are available without CapEx or OpEx requirements for the MNO. Shush is a member of the GSMA, MEF, and CPaaS Alliance, and holds SOC 2 Type II certification. The company is headquartered in Fort Lauderdale, Florida.
