Frequently Asked Questions
What is NetFlow?
NetFlow is a Cisco technology that summarises network conversations into flow records, listing source, destination, ports, protocol and volume. It shows who talks to whom without storing full packets.
What is the difference between NetFlow and sFlow?
NetFlow tracks flows on the device, while sFlow samples packets and counters at intervals, scaling well on fast links. IPFIX is the open standard based on NetFlow.
How does flow data help security teams?
Flows reveal scans, data exfiltration and unusual traffic spikes cheaply across the whole network. This free intermediate Codelivly room teaches how to read and analyse them.
