Velociraptor is a digital forensics and incident response platform, endpoint detection and response system, and visibility tool. It provides a query engine and remote forensic collector used to hunt for indicators of compromise and perform triage across a fleet of hosts. The system is distinguished by its specialized query language for interrogating host state and parsing binary files. It features a notebook environment that combines markdown documentation with executable query cells to standardize investigative workflows and enable collaborative reporting. The platform covers a wide range o
Falco is an eBPF runtime security monitor and cloud native detection engine that identifies abnormal behavior and security threats across hosts and containers. It functions as a Linux kernel event auditor, capturing system calls and kernel events in real-time to detect malicious activity. The system distinguishes itself through a rule-based threat detection model that evaluates system activity against a library of community-maintained rules and custom security definitions. It enriches raw kernel events with container and Kubernetes metadata to provide observability into isolated environments
Security Onion is a security information and event management platform and network security monitoring suite. It functions as an intrusion detection system and a network traffic analysis tool designed to identify malicious activity and network intrusions through signature-based detection and host-based monitoring. The platform integrates a security case management system to organize investigations by tracking detections and grouping related security events. It provides capabilities for full packet capture, network metadata extraction, and the collection and indexing of security logs from dive
Tetragon is an eBPF-based runtime security and observability toolset designed for Linux and Kubernetes environments. It functions as a security policy manager, observability agent, and enforcement engine that hooks into kernel functions and tracepoints to detect privilege escalation, container escapes, and unauthorized system activity. The project distinguishes itself through its ability to perform real-time, in-kernel enforcement, allowing it to synchronously terminate malicious processes or modify function return values before a system call completes. It provides deep Kubernetes integration
