Overview

Open-source Endpoint Detection and Response (EDR) and endpoint telemetry tools are security solutions designed to collect, analyze, and respond to data generated by endpoints within an organization. Security teams utilize these tools to monitor endpoint activities, detect threats, and enhance visibility across diverse environments to maintain robust security postures.

Primary Security Objectives

Enable security operations, testing, and validation
Support prevention, detection, response, and assessment activities
Improve security effectiveness, visibility, and maturity

Who Uses These Tools

Blue teams, Red teams, Purple teams
SOC analysts, security engineers, penetration testers
AppSec, CloudSec, IAM, and GRC practitioners

Where They Are Used

Enterprise IT, cloud, and hybrid environments
Security operations centers (SOC)
Testing labs, CI/CD pipelines, and production systems

How They Work (High Level)

These tools operate by collecting telemetry data from endpoints, such as process activity, network connections, and system logs, to identify suspicious behavior. They analyze this data using rule-based or behavioral detection methods and enable automated or manual response actions to mitigate threats. Additionally, they provide visibility and context to support incident investigation and continuous security improvement.

Tool Categories and Capabilities
