Protocols

This page details the protocols detected by the Netify Agent. The complete catalog is also available through the Protocol API.

You can reference the protocol ID, category ID, and category tag in flow expressions to accurately identify and control network traffic at the protocol layer. The protocol information is also provided in several telemetry data formats.

Protocol Network Layer

The protocol layer highlights the core communication method within a flow (e.g., HTTPS, QUIC, DNS, STUN), offering integrators a clear, structured view of network traffic behavior.

The Protocol layer sits above IP Protocol in Netify's network classification layers, adding communication-level context to the network-level foundation that layer establishes. It also underpins the more specific Application and Intelligence layers, preserving visibility into how traffic communicates even when a request is encrypted and grouped under a broad protocol like HTTPS.
