In their own words
Colander
Colander is a web-based platform for case management, digital investigations, and shared knowledge building. It organizes evidence and investigative knowledge into cases, supports team collaboration, and allows information sharing with other organizations. A web graph editor represents artifacts, actors, observables, and events. Through Threatr, users can retrieve intelligence from VirusTotal, MISP, and OTX AlienVault. Colander can collect and sign PiRogue artifacts, track their integrity and authenticity, and analyze decrypted network traffic and payloads. Payloads can be decoded with CyberChef, while YARA rules can be applied to network traffic. Users can generate data transmission reports and create feeds in different formats. A Python 3 library abstracts the REST API and uses an API key from the user profile. The project is open source under AGPL v3, with API, Linux, web, and self-hosted options. Deployment guidance recommends current Debian, at least 4 cores, 4 GB RAM, 500 GB storage, and a public IP.
GRR Rapid Response
GRR Rapid Response is an incident response framework for remote investigation and live forensics. Client agents run on target systems, while server infrastructure provides a web interface and API. From the framework, analysts can search and download files, search the Windows registry, access raw filesystems, and collect forensic artifacts. GRR also supports remote memory analysis with YARA and lets analysts schedule fleet hunts, including for machines offline when a hunt is scheduled.
The integration list includes Colab, Splunk, BigQuery, Elasticsearch, Timesketch, Turbinia, Python API clients, and an HTTPS REST API with OpenAPI definitions. The maker says client-server communication is encrypted against eavesdropping and impersonation; approval-based controls can gate sensitive actions. GRR is self-hosted, open source under Apache License 2.0, and listed at free. Clients normally run as root and can read system data, so access to the server carries equivalent access to client machines. The core team does not offer a helpdesk, paid setup assistance, feeds, or consulting.
