kentik/kproxy
Kentik allows customers to send the network data collected from their devices to Kentik Detect securely using a downloadable software agent called "kproxy." Among other functions, kproxy acts as a NetFlow proxy agent that enables the local encryption of flow records (NetFlow v5/v9, IPFIX, and sFlow) before those records are forwarded to Kentik.
