Full Packet Capture
Arkime (formerly Moloch) is a large-scale, open-source, indexed packet capture and search tool.
It includes a new app! Check out Cont3xt.
Meet the developers and other Arkimists at our Office Hours.
Augment your current security infrastructure to store and
index network traffic in standard PCAP format.
Arkime is not meant to replace Intrusion Detection Systems (IDS)
but instead provides more visibility.
Security
Access to Arkime is protected by using HTTPS with digest passwords or by using an authentication-providing web server proxy. All PCAPs are stored on the installed Arkime sensors and are only available through the Arkime web interface or API. Arkime supports encrypting PCAP files at rest.

Scalability
Arkime is designed to be deployed across multiple clustered systems, providing the ability to scale to handle multiple gigabits per second of traffic. PCAP retention is based on available sensor disk space, while metadata retention is based on the scale of the OpenSearch/Elasticsearch cluster. Both can be increased at any time.
Interface
A web application is provided for PCAP browsing, searching, analysis, and PCAP carving for exporting. Arkime stores and exports all packets in standard PCAP format, allowing you to use your favorite PCAP ingestion tools during your analysis workflow.
APIs
Exposed APIs allow PCAP data and JSON-formatted session data to be downloaded directly.
