See Why ReliaQuest Was Named in The Forrester Wave™: External Threat Intelligence Service Providers, Q3 2026

“Threat intelligence as the nervous system of the agentic SOC.”

Your security team is the defense layer of the business—and a defense only as strong as what it knows about the opponent. GreyMatter makes that defense stronger with continuous intelligence on the adversaries targeting you, driven straight into detection, containment, investigation, and response.

In The Forrester Wave™: External Threat Intelligence Service Providers, Q3 2026, Forrester describes ReliaQuest's vision as positioning “threat intelligence as the nervous system of the agentic SOC.” ReliaQuest received the highest score possible (5 out of 5) in the AI agent maturity, product security, and roadmap criteria.

The capabilities that set GreyMatter apart:

1. Intelligence That Drives Action – GreyMatter runs threat intelligence across your connected tech stack in plain language, so analysts move from discovery to investigation to response in one place.
2. Data Normalization and Correlation at Scale – The Universal Translator maps every field from any connected technology to the Open Cybersecurity Schema Framework (OCSF) the moment it connects, correlating security data across tools without forcing you to centralize it first.
3. Practical AI Agents with Validation Controls – Forrester noted that ReliaQuest “offers a range of practical AI agents built on robust architectures with appropriate testing and validation controls.” Six agentic teammates investigate and respond across every discipline, 24/7.
4. Continuous Detection Engineering – GreyMatter builds and tunes detection content natively across existing tools, keeping coverage current as threats change and removing manual rule-writing.
5. Threat Intelligence from Everywhere – 50+ open and closed sources, open, deep, and dark web monitoring, CVEs and vulnerability intelligence, and human-led research—correlated with your assets, identities, and IOCs in a single model.
