Which tools you using for Threat hunting: Velociraptor, OSquery or GRR?

1. Architecture and Deployment:

• Velociraptor: Velociraptor uses a client-server architecture and can be deployed on-premises or in the cloud. The server component runs on Linux and supports Docker containers for easy deployment. The client component can run on Windows, macOS, and Linux.
• OSquery: OSquery uses a client-server architecture and can be deployed on-premises or in the cloud. The server component runs on Linux and supports Docker containers for easy deployment. The client component can run on Windows, macOS, and Linux.
• GRR: GRR uses a client-server architecture and can be deployed on-premises or in the cloud. The server component runs on Linux and can be deployed using Docker or as a standalone installation. The client component can run on Windows, macOS, and Linux.

2. Data Collection:

• Velociraptor: Velociraptor collects data using a combination of agents and collectors. Agents run on endpoints and collect data locally, while collectors run on the Velociraptor server and collect data remotely from endpoints.
• OSquery: OSquery collects data using a lightweight agent that runs on endpoints. The agent collects data locally and sends it to the OSquery server for analysis.
• GRR: GRR collects data using agents that run on endpoints. The agents can collect data locally or remotely, depending on the configuration.

3. Data Analysis and Querying:

• Velociraptor: Velociraptor uses a query language called VQL (Velociraptor Query Language) for data analysis and querying. VQL is based on SQL and supports a wide range of data types and operators.
• OSquery: OSquery uses SQL for data analysis and querying. OSquery provides a wide range of built-in tables that can be used for security analysis, and also supports custom tables.
• GRR: GRR uses a Python-based query language called YARA for data analysis and querying. YARA is a powerful pattern matching engine that can be used to search for specific strings or patterns in data.

4. User Interface:

• Velociraptor: Velociraptor provides a web-based user interface for data analysis and querying. The user interface is highly customizable and supports advanced features such as live streaming of data.
• OSquery: OSquery provides a command-line interface and a web-based user interface for data analysis and querying. The web-based user interface is provided by third-party tools such as Fleet or Kolide.
• GRR: GRR provides a web-based user interface for data analysis and querying. The user interface is highly customizable and supports advanced features such as remote live forensics.

5. Integrations:

• Velociraptor: Velociraptor provides a wide range of integrations with other tools, including Elasticsearch, Kibana, and Splunk.
• OSquery: OSquery provides a wide range of integrations with other tools, including Elastic Stack, Graylog, and Syslog.
• GRR: GRR provides integrations with other tools such as Elasticsearch and TheHive for incident response and case management.

Overall, each tool has its own strengths and weaknesses, depending on the needs and goals of the security team. By evaluating the technical capabilities of each tool, security teams can choose the tool that best meets their needs and enhances their threat hunting capabilities.
