## What it is
Arkime is an open-source, large-scale network analysis, full packet capture, and session indexing system that stores traffic in standard PCAP format and indexes searchable metadata in OpenSearch/Elasticsearch. It includes a web UI for browsing and exporting sessions, plus companion tools like Parliament (cluster health) and Cont3xt (indicator enrichment).

## Use cases
- capture and index full network packets at scale for security investigations
- search and browse network session metadata with a web interface
- investigate security incidents by drilling from session records down to raw PCAP bytes
- run enriched NetFlow-style metadata-only monitoring without storing full packets
- enrich IOCs like IPs, domains, and hashes using OSINT sources
- monitor health of multiple Arkime capture clusters from one dashboard
- export PCAPs for analysis in tools like Wireshark

## When to choose
- you need full packet capture and fast indexed search across tens of gigabits per second of traffic
- you want to augment an existing IDS/SIEM with searchable network session ground truth
- you need self-hosted network security monitoring with standard PCAP storage and APIs
- you want long-retention, metadata-only network visibility on limited disk

## When to avoid
- you need a lightweight host-based or endpoint monitoring solution
- you cannot operate an OpenSearch/Elasticsearch cluster or dedicated capture sensors
- you only need simple log aggregation rather than packet-level network analysis
- you require Windows-native deployment, as Arkime targets Linux sensors
