Network telemetry Defined<\/h2> <\/div>\n

Network telemetry refers to the collection, transmission, and analysis of data generated by network devices, connections, applications, and traffic flows. It provides security and IT teams with visibility into what is happening across a network, helping them monitor performance, identify anomalies, investigate incidents, and detect potential threats.<\/p><\/div> <\/div>\n <\/div>\n\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Network telemetry can include information such as network flows, packet metadata, connection records, DNS requests, IP addresses, ports, protocols, application activity, device status, and authentication events. Depending on the monitoring technology, telemetry may also include detailed packet or session-level information that provides greater context about network communications.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Network telemetry is generated as users, devices, applications, and services communicate across a network. Network infrastructure such as routers, switches, firewalls, gateways, endpoints, and cloud environments can generate telemetry data.<\/p>

This information is collected through technologies such as NetFlow, IPFIX, sFlow, packet capture<\/a>, network sensors, APIs, and security monitoring tools. The collected data is then sent to centralized platforms for storage, correlation, analysis, and visualization.<\/p>

Modern network telemetry can operate continuously, allowing organizations to monitor network activity in near real time rather than relying solely on periodic logs or manual investigations.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
