Global secure sim clientless sase architecture for cellular devices

Abstract

A clientless security system to secure cellular devices across a network in a cloud-based environment. The clientless security system includes a tenant with multiple cellular devices, tunnels for transmitting traffic, and a traffic steering module for directing traffic toward a gateway. The clientless security system further includes gateways to apply policies based on a device profile and an alert generator. The traffic steering module provides a SIM with network identifiers, configures the SIM with a custom network identifier, creates a device-to-IP mapping, and distributes the device-to-IP mapping to gateways in real-time. The gateways apply multiple policies based on a device profile, receive traffic from the traffic steering module, and perform a reverse lookup. The gateways further determine a device identity, apply policies, and forward traffic to a destination. The alert generator is also used to notify the tenant of further remediation in case of policy violations.
