What Glean Packets is

Glean Packets is a paid, self-hosted web PCAP analyzer from Glean Co. that keeps capture data on your own server while you inspect it in a browser. It accepts .pcap, .pcapng, and .gz files, parses them in parallel, and indexes them in SQLite. Protocol decoding covers Ethernet, IP, TCP, UDP, ICMP, and DNS, with a hex viewer for packet contents. DNS searches can use names, IP addresses, or record types and link queries with answers. Flow views show top flows, latency distribution, and packets-per-second charts. You can filter packets by protocol for .pcap.gz export or begin live capture in the browser. Remote capture works across nodes, with PCAP merging and unified cluster access without a single point of failure. Optional Glean Agent searches and summarizes captures through a self-hosted or customer-provided LLM endpoint; a GPU is recommended. Signature detection accepts YAML rules and regex, with severity and confidence scores from 0 to 100. The interface supports English and Japanese desktop or mobile browsers.
