Automated Linux Defense Validation
through Adversary Emulation.
Designed with Defenders in Mind.
EDRmetry Pulse is a user-friendly, automated tool for simulating adversary behavior on corporate Linux networks. It enables cybersecurity professionals to test Linux telemetry collection, evaluate detection capabilities, verify security controls, and enhance Linux incident response procedures. With a minimal learning curve and time-saving features, EDRmetry Pulse offers the quickest way to understand the true status of detection coverage and EDR/XDR/SIEM threat alerting in a continuous and automated format. It is the only Breach and Attack Simulation platform available on the market dedicated exclusively to Linux environments and containing advanced and low-level offensive tests.
EDRmetry Pulse, built on the EDRmetry Matrix, automates the execution of over 300 offensive techniques (TTPs) derived from real-world Linux attack scenarios. It offers a comprehensive Linux offensive catalog, enabling users to launch individual “EDRmetries” or chain them together for advanced testing.
EDRmetry Pulse is tailored for Cyber Security Professionals, with maximum value for:
EDRmetry Pulse is your ultimate companion in mastering the Linux threat landscape through offensive security automation. Designed with defenders in mind, it bridges the gap between red and blue teams by emulating real-world Linux attacks in a controlled, systematic, and intelligent way—so you can stop threats before they escalate.
EDRmetry is an advanced tool designed to evaluate and enhance your Linux security system posture, with a specific focus on assessing EDR/XDR/SIEM detection capabilities. It serves as a comprehensive, vendor-agnostic playbook for offensive Linux testing and operations, providing cybersecurity professionals with the means to thoroughly test and improve their Linux-based security infrastructure.
EDRmetry addresses several critical challenges in the cybersecurity landscape:
EDRmetry stands out in several ways:
EDRmetry enables a wide range of security tests, including but not limited to:
EDRmetry is designed to be vendor-agnostic, allowing you to:
Yes, EDRmetry is designed with flexibility in mind:
EDRmetry is designed to be accessible to a range of users:
Yes, Defensive Security provides several additional services:
Reduce manual effort by automating and chaining offensive techniques, allowing your team to validate the effectiveness of Linux EDR or Runtime Security engines in real-time. EDRmetry Pulse ensures your defenses aren’t just theoretical—they're tested and proven.
Uncover blind spots in your detection pipelines, telemetry flows, and data source correlations. By replicating adversary behavior, EDRmetry Pulse highlights exactly where your current tools are falling short, so you can close the gap before attackers exploit it.
Use EDRmetry Pulse as a foundation for meaningful internal Red vs Blue team exercises. Improve coordination, sharpen your response strategy, and gain deeper insight into Linux-specific TTPs and forensic artifacts.
Focus your resources where they matter most—building better detections and expanding your threat-hunting capabilities. With EDRmetry Pulse, you maintain an active defense posture while aligning your efforts to real adversary behavior.
EDRmetry Pulse helps you define meaningful criteria for evaluating Linux EDR and SIEM solutions. Ask vendors the right questions, backed by technical insight and offense-driven evidence.
Evaluate the EDR/SIEM effectiveness and visibility, or use EDRmetry for Red vs Blue team skill development in the next-generation, hands-on format of internal Linux security workshops/training
"Understanding the effectiveness of your Linux cybersecurity measures is more critical than ever. While you invest in expensive security tools like EDR/XDR, set up Security Operations Centers (SOCs), and implement Security Information and Event Management (SIEM) systems, how can you truly assess their performance against real-world Linux threats and complex attacks? How to choose and validate EDR/SIEM for your Linux needs? Learn about EDRmetry."
EDRmetry Pulse provides more than 300 Offensive Unit Tests with a modular approach, enabling flexibility for chaining them into complex attack scenarios. Each test is backed by documentation for quick understanding and usage. EDRmetry Pulse provides security teams a robust foundation for offensive testing and validation of Linux-focused EDR/SIEM solutions.
All offensive test definitions, called "EDRmetries," are written in Ansible YAML for clear test logic, easy customization, and chaining. The Ansible engine manages execution via SSH communication, eliminating the need to install a dedicated agent. Ansible playbooks, stored in a central repository or local directory, define the core testing logic and are integrated into EDRmetry Pulse, a web application that enables on-demand test execution.
EDRmetries support parameterization, allowing for easy adaptation to the client's environment. The basic design assumption was to minimize the number of static values, such as TARGET_INTERNAL_IP/TARGET_EXTERNAL_IP, C2_EXTERNAL_IP/C2_INTERNAL_IP, C2_SLIVER_MTLS_PORT, and others, such as commands executed from the RCE exploit level like PHP_SYSTEM_COMMANDS, or pid values for hiding, ex, MOUNT_PID_TO_HIDE, to name just a few.
A dedicated testing environment, ideally located in a customer’s dedicated VLAN, is based on the assumption that testing virtual machines are based on "Golden" images to achieve maximum compatibility with production systems. As part of the Preparation phase, EDRmetry provides a set of early-stage deployment automations that enable the local delivery of network services within vulnerable container images, binaries that facilitate LPE, and other types of security misconfigurations. The goal is to achieve a true contextual execution as close as possible to that observed in real-world attacks. Only in this way will you see whether your detection, telemetry, or alerting can actually work in the event of a real attack.
Choose and install on the TARGET VM the Linux EDR/Runtime Security/SIEM engine you want to evaluate.
Navigate to the EDRmetry Matrix and identify relevant techniques from a comprehensive database.
Choose Tactic, search Technique and pick a technique EDR-ID.
Prepare attack chains or manually execute single offensive tests on TARGET_X Vms.
Check telemetry, detections, and alerts generated within the chosen EDR/Runtime/SIEM platform.
