US Patent 11438357 Endpoint network sensor and related cybersecurity infrastructure

In one or more examples, an advanced form of network endpoint sensor is deployed to an endpoint device to provide local monitoring and reporting of network traffic flowing to and/or from the endpoint device. For example, such network endpoint sensors may reduce reliance on other types of monitoring component (such as mirrors/TAPs) and/or complement functionality of other type(s) of monitoring component (e.g. in a deployment with “roaming” endpoints). In one or more examples, network data may be linked or otherwise associated with endpoint data locally at an endpoint device. In one or more examples, such linking may be performed locally prior to reporting, response and/or remediation.
