What is sFlow in Cybersecurity?
sFlow is a multi-vendor sampling protocol that captures a statistical sample of network packets and counters for traffic analysis. Unlike NetFlow, which tracks complete flows, sFlow samples packets at configurable rates, making it lighter on device resources while still providing accurate traffic visibility at scale.
Why sFlow Matters for Your Cybersecurity Career
sFlow gives security teams traffic visibility in environments using non-Cisco equipment. SOC analysts use sFlow data alongside NetFlow to detect anomalous traffic patterns and potential threats. Security engineers select between sFlow and NetFlow based on their infrastructure vendor mix and monitoring requirements.
