Enabling secure silent network authentication

What is Shush Sherlock?

Sherlock is the center of the Network Authentication experience. At the Sherlock core is the API gateway which powers the CAMARA compliant API requests from authorized enterprise developers at CPaaS partners and enterprise brands such as financial institutions.

Sherlock's proprietary logic retrieves valuable network attribute data deep within the MNOs network to facilitate 47 APIs including Number Lookup, Silent Authentication, SIM Swap Detection, and Device Status.

Finally, Sherlock is the monetization platform which allows MNOs to unlock the value of their network by setting the price and access to APIs and power the billing for utilization.
