Accelerate the Threat Detection, Investigation, and Response Process

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


Modernizing and Automating the TDIR 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 TDIR process leveraging your existing security tools.

Maximize Existing Security Investments

You know the tools that work best for your environment. A modern TDIR 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 TDIR solution needs to monitor that fluid attack surface to facilitate threat hunting and detect malicious activity.

Get Ahead with

Handling security incidents can be manual, repetitive work, and you have limited time. Your TDIR solution needs to automate investigations and response actions to reduce manual and repetitive tasks.


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

How GreyMatter Works

Accelerating Your TDIR Process

ReliaQuest delivers threat detection capabilities powered by the latest threat intelligence, automated investigations that selectively stitch data across your existing tools, and automated response actions using your existing security technologies—all from an integrated platform.


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 with existing tools enables you to quickly detect threats and take action to mitigate them.

Improve Managed Detection and Response (MDR)

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
for Faster Incident Response

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

Technology Capabilities

Better TDIR with ReliaQuest GreyMatter

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

With integrations across all security tools, whether on-premises or in one or more clouds, enables GreyMatter to ingest data and detect threats across your existing security investments.

  • 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 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. This combined with automation allows enrichment of investigations with telemetry and context from existing tools without requiring analysts to manually pivot across tools and sift through data.

  • 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 threat hunting to 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 platform-driven analysis.

Swift 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
