## What it is
MozDef is Mozilla's Enterprise Defense Platform, an open-source SIEM-style application for automating security incident handling and enabling real-time collaboration among incident handlers. It is built on Python and the ELK stack (Elasticsearch, Logstash, Kibana) and was designed to process hundreds of millions of events per day.

## Use cases
- set up a self-hosted SIEM for security event monitoring
- automate security incident handling and response workflows
- aggregate and search security logs in Elasticsearch
- get real-time alerts and metrics on security events
- coordinate incident handler collaboration and information sharing
- deploy a security monitoring platform in AWS via CloudFormation

## When to choose
- you want to study or fork an open-source SIEM architecture
- you need a reference design for ELK-based security event processing
- you are willing to maintain a fork yourself

## When to avoid
- you need a maintained, supported SIEM - the project is officially deprecated
- you want production security tooling without forking and maintaining it
- you need current Elasticsearch version compatibility or security patches

## Facets
- artifact type: application
- maturity: abandoned

- domain: security, monitoring, big-data
- platform: python, cloud, self-hosted
