As cyber threats become more sophisticated and persistent, organizations face increasing pressure to maintain visibility into their endpoints, respond quickly to incidents, and gather forensic data without delay. Traditional security tools often fall short in providing the flexibility, depth, and responsiveness required in fast-paced investigations or complex enterprise environments. Velociraptor steps in as a modern, open-source solution tailored specifically for digital forensics and incident response (DFIR) professionals.
Rather than offering a monolithic, one-size-fits-all suite, Velociraptor provides a flexible toolkit grounded in precision, transparency, and customization. From real-time endpoint visibility and centralized orchestration to offline forensic collection and customizable artifact-driven investigations, Velociraptor covers a wide array of use cases that make it an invaluable asset for incident response teams, threat hunters, compliance auditors, and forensic investigators.
This comprehensive overview explores all of Velociraptor’s core components, deployment models, tools, and use cases—explaining how each can be leveraged to strengthen digital investigations and reduce the time to detect and respond to cyber threats.
The Velociraptor Platform at a Glance
Velociraptor is a fast, scalable, and extensible platform built for endpoint monitoring, threat detection, and forensic collection. Its architecture is based on a client-server model, where lightweight agents run on endpoints and communicate with a centralized server. What distinguishes Velociraptor from traditional EDR or SIEM solutions is its use of Velociraptor Query Language (VQL), a forensic-specific scripting language designed to query a wide range of system artifacts in real time.
Rather than relying on precompiled modules or closed signatures, Velociraptor allows DFIR teams to write or reuse artifacts—reusable code snippets that define how and what to collect from endpoints. This means every collection task, search, or hunt can be customized to suit the environment, investigation scope, or compliance need.
Core Product Components
1. Velociraptor Server
The server component serves as the control hub for managing client endpoints, launching queries, scheduling collections, analyzing results, and enforcing access control. The web-based GUI provides investigators with powerful tools to orchestrate investigations across an entire fleet of endpoints.
Features include:
- Endpoint dashboard with system metadata
- Central artifact repository
- Live VQL query execution
- Searchable forensic history per client
- Integrated file browser and registry viewer
- Event monitoring and alerting
- Certificate-based access control
The server maintains forensic timelines, system inventories, and real-time insights into all connected endpoints, empowering analysts to detect anomalies and respond immediately.
2. Velociraptor Client
The client is a lightweight binary designed for installation on Windows, Linux, or macOS systems. Once deployed, the client connects to the server using encrypted communication and awaits commands. Clients are extremely resource-efficient, often consuming less than 1% CPU while idle, making them suitable even for legacy systems or devices under load.
When queried, the client can:
- Execute VQL-based forensic scans
- Collect artifacts like logs, registry keys, file metadata
- Stream events like process creation or network connections
- Monitor filesystem or registry changes
- Run scheduled collection policies in the background
Clients can be installed persistently or executed in a temporary mode during incident response efforts.
3. Velociraptor Query Language (VQL)
VQL is the language that powers Velociraptor’s flexibility. It resembles SQL but is adapted for forensic data structures like filesystems, registry paths, process tables, and event logs. Analysts use VQL to write artifacts, which can then be reused, shared, or versioned in the Velociraptor server.
Common VQL use cases include:
- Searching for file hash matches
- Extracting timestamps from log entries
- Parsing MFT records
- Monitoring for DLL injection indicators
- Filtering out benign activity during triage
The modularity of VQL makes Velociraptor ideal for dynamic and evolving investigations where canned queries fall short.
4. Artifact Library
Velociraptor ships with a comprehensive collection of prebuilt artifacts covering:
- Windows event logs and audit policy
- Prefetch, ShimCache, and AmCache
- Browser history and cache
- Startup items and scheduled tasks
- File system traversal and metadata scraping
- User session and login details
- Registry keys and service configurations
Organizations can also create custom artifacts to support proprietary tools, application logs, or internal workflows. Artifacts are easily versioned, organized, and shared within teams, making them a valuable part of any DFIR playbook.
Velociraptor Offline Collector
For environments that are disconnected, sensitive, or restricted, Velociraptor offers its Offline Collector—a standalone version of the platform designed to run without server communication.
The Offline Collector is a prebuilt binary configured with selected artifacts and parameters. Once executed on a target system, it collects the requested data and packages it into an encrypted archive. This file can then be imported into the Velociraptor server for review and analysis.
Key benefits:
- Operates independently of network access
- Supports encryption (password, X.509, PGP)
- Can include third-party forensic tools
- Customizable resource usage and execution time
- Perfect for air-gapped, legacy, or compromised systems
This tool is indispensable in scenarios where traditional telemetry cannot be established—such as in government, critical infrastructure, or breach containment operations.
Live Monitoring and Event Collection
In addition to forensic triage and data retrieval, Velociraptor provides real-time monitoring of endpoint activity. By subscribing to system events, Velociraptor can alert analysts to abnormal behavior as it happens.
Event monitoring capabilities include:
- Process creation with command-line logging
- File modifications in sensitive directories
- Network connection attempts
- Registry value changes
- Driver and module loads
Combined with customizable VQL rules, teams can build advanced detections tailored to their environment. These events can be streamed back to the server, visualized in the GUI, or used to trigger additional collections automatically.
Advanced Use Cases
Threat Hunting
Velociraptor excels at large-scale threat hunting campaigns. Analysts can push a single query to hundreds or thousands of machines and return results quickly. Searches for persistence mechanisms, fileless malware artifacts, or lateral movement behaviors can be scripted and executed centrally, without overwhelming system resources.
Rapid Triage
Using prebuilt triage profiles, incident response teams can scan potentially compromised machines and return actionable insights within minutes. The ability to define targeted artifact sets speeds up investigation and reduces data overload, especially during ransomware or insider threat scenarios.
Compliance Auditing
Velociraptor can enforce scheduled collections of policy data, user access logs, or system configurations. This makes it useful for regulatory compliance monitoring, audit preparation, and security posture assessments without requiring external software or agents.
Evidence Preservation
During incident response, preserving volatile evidence is critical. Velociraptor’s ability to collect data without modifying the system, combined with its logging and encryption capabilities, ensures proper forensic chain-of-custody and admissibility in legal contexts.
Community and Ecosystem
Velociraptor is supported by an active and growing open-source community of security professionals, DFIR practitioners, and developers. Community-contributed artifacts, presentations, and updates ensure the platform stays current with emerging threats and investigative techniques.
Additionally, Velociraptor supports RESTful APIs for integration with SIEMs, SOAR platforms, ticketing systems, and automation workflows. Organizations can build pipelines that trigger Velociraptor queries based on detection events or incident tickets—turning it into a fully automated forensic responder.
Why Velociraptor Matters
Unlike many commercial endpoint tools, Velociraptor gives complete control to the operator. Investigations aren’t limited by vendor logic, black-box algorithms, or license restrictions. Teams can adapt their tools on the fly, define their own logic, and share methodologies across teams or organizations.
This transparency, combined with its high performance and cross-platform support, makes Velociraptor an ideal choice for security teams that need precision, speed, and trustworthiness in their investigative workflows.
