    Abstract: In one embodiment, a gateway to a zero trust network applies an access control policy to an endpoint device attempting to access a cloud-based application hosted by the zero trust network. The gateway acts as a reverse proxy between the endpoint device and the cloud-based application, based on the access control policy applied to the endpoint device. The gateway captures telemetry data regarding application traffic reverse proxied by the gateway between the endpoint device and the cloud-based application. The gateway detects an anomalous behavior of the application traffic by comparing the captured telemetry data to a machine learning-based behavioral model for the application. The gateway initiates a mitigation action for the detected anomalous behavior of the application traffic.

    Abstract: Techniques that provide proactive and intelligent packet capturing are described herein. In one embodiment, a method includes storing information associated with a plurality of user equipment (UE) sessions of a plurality of UEs within a mobile network; detecting an anomaly associated with at least one UE session of at least one UE based, at least in part, on the information stored for the at least one UE session; and activating a trace for the at least one UE session based, at least in part, on detecting the anomaly associated with the at least one UE session, wherein activating the trace comprises capturing packet information for a data packet flow associated with the at least one UE session at one or more data-path network elements of a plurality of data-path network elements within the mobile network.

    Abstract: A method of controlling performance of a wireless device is performed by a node that is in electronic communication with a cellular network. The node includes a processor, a non-transitory memory, and a network interface. The method includes receiving a performance value characterizing a performance of a communication channel between a wireless device and a wireless access point. In some implementations, the wireless device and the cellular network are associated with different radio access technologies (RATs). The method includes determining whether the performance value breaches a performance criterion for the wireless device. The method includes adjusting a first amount of data transmitted to the wireless device from a base station of the cellular network and a second amount of data transmitted to the wireless device from the wireless access point. In some implementations, the combined first and second amounts of data satisfy the performance criterion for the wireless device.

    Abstract: The disclosed technology relates to systems and methods for automatically scaling down network resources, such as servers or gateway instances, based on predetermined thresholds. A system is configured to detect a reduction in one or more network metrics related to a first server, and instruct the first server to issue a rekey request to a plurality of devices connected to the first server. The system is further configured to instruct a load balancer to route to at least one other server responses from the plurality of devices to the rekey request, and determine a number of connections remaining between the first server and the plurality of devices. The system may be further configured to instruct the load balancer to terminate the first server based on the detected number of connections remaining between the first server and the plurality of devices.
