Arkime (formerly Moloch) is a large-scale, open-source, indexed packet capture and search tool.
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.
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.

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.
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.
Exposed APIs allow PCAP data and JSON-formatted session data to be downloaded directly.

Choose the dropdown menu on any field to view actions that can be performed on that field, such as exporting unique values and opening the SPI Graph page.
Choose the cancel button on the top right of the page if the page is taking a long time to load data or you made a mistake when you issued a query.
The Session Profile Information (SPI) Graph page shows a temporal view for the top unique values of any field.
The first timeline graph and map show an aggregation of all the results below. Choose the x button on this map to hide all maps.
Make a selection from the SPI Graph dropdown menu on the top left to view the unique values for different fields.
