Summary
This post introduces on-demand packet captures from Cloudflare's global network, a new capability for customers using Magic Transit and Magic WAN. This feature provides granular visibility into network traffic by allowing users to request and analyze packet capture files. It addresses the challenge of fragmented visibility in modern networks by centralizing packet capture capabilities at the edge. The post details the technical implementation using nftables and tcpdump, and highlights its utility for both network troubleshooting and security analysis, directly contributing to the ability to identify and mitigate threats.
