Accelerate the Detection, Investigation, and Response Process

The GreyMatter platform provides a unified detection, investigation, and response (DIR) process that increases visibility across your entire attack surface, reduces complexity, and efficiently manages risk for your business.

Defining Modern DIR

Modernizing and Automating the DIR Process

Cyberthreats are a nonstop fact of today’s business, but what separates good from great security operations is the ability to streamline and automate the DIR process leveraging your existing security tools.

Maximize Existing Security Investments

You know the tools that work best for your environment. A modern DIR approach uses bi-directional API integration to help you get the most out of them without requiring you to pivot.

Cover Your Entire
Attack Surface

Your internal and external attack surface is broad and grows with every new endpoint, cloud service, or business application. Your DIR solution needs to monitor that fluid attack surface to identify and respond to potential threats.

Get Ahead with

Cybersecurity can be manual, repetitive work, and you have limited time. Your DIR solution needs to automate investigations and response actions to reduce manual and repetitive tasks while accelerating response.


A key to improving DIR is easily measurable metrics across your DIR workflow. SOC metrics should measure visibility, effectiveness, and ability to respond across your tools and teams.

How GreyMatter Works

Accelerating Your DIR Process

ReliaQuest delivers the best detection capability powered by the latest threat intelligence, automated investigations that selectively stitch data across your existing tools, and response actions using your existing security technologies—all from a single UI.


Comprehensive detection coverage, mapped to the MITRE ATT&CK® framework, can be deployed in hours to locate emerging threats faster.

Get More from Your Existing Security Tools

Bi-directional integration into existing tools enables you to quickly detect and take action to mitigate threats.


Avoid tool pivots by automating the investigation process with just-in-time data stitching across your tools, enrichment with threat intel, and playbooks to speed response.

Automated Playbooks
Speed Response

Playbook automation applied to existing tools reduces manual work and provides consistent response across your environment.

Technology Capabilities

Modernize DIR with a
Security Operations Platform

ReliaQuest GreyMatter, built on an Open XDR architecture, provides bi-directional integration across all security tools, whether on-premises or in one or more clouds, to ingest data and automate actions.

Threat Detection Across All Your Security Tools

Bi-directional API integration across all security tools, whether on-premises or in one or more clouds, enables GreyMatter to ingest data and automate actions using what you already have.

  • Stay ahead of threats and reduce the impact of events with 600+ detection rules curated for mixed-vendor environments.
  • Continuous updates based on learning from across a growing customer ecosystem minimize alert noise.
  • Detections tuned to your environment prevents your having to become an expert in all technologies.

Investigation Powered by Automation

GreyMatter’s Open XDR architecture provides bi-directional integration with your security tools combined with automation to autopopulate investigation information and accelerate response actions through existing tools.

  • Automation informs investigations by auto-querying relevant technologies, de-duping and contextually enriching alerts with data from related technologies, intel, and historical information to facilitate investigations and avoid “swiveling” between tools.
  • GreyMatter removes the tedium of tool integration and data model mappings, unifying data collection and contextual enrichment to respond to threats faster while reducing alert fatigue.
  • GreyMatter provides the transparency and flexibility for you to participate, observe, or simply leverage the investigation output.

Accelerated Response Using Existing Technology Investments

Automate response and take action fast to reduce MTTR from hours to minutes.

  • Bi-directional API integration allows for automated execution and validation of response playbooks across your SIEM, endpoint, network, cloud, and on-premises solutions.
  • Customized playbooks with prebuilt actions and workflows automate actions to accelerate response, provide consistency, and avoid errors.
  • ReliaQuest provides continuous monitoring of all resources, applications, and security tools for real-time situational awareness.

There’s such an immense amount of information to consume and staffing a Tier 1 or 2 SOC would be cost-prohibitive. That’s one of the reasons why ReliaQuest is such a huge benefit for us – GreyMatter Open XDR-as-a-Service helps us cut down on managing tools and allows my team to focus on the bigger picture projects. Trey Tunnell Director of Cybersecurity Operations
