The People Behind the Numbers

Role Industry Employees Revenue
CISOLighting Solutions30,000$6B
Deputy CISOManufacturing20,000$7B
Director of Security OperationsAerospace9,000$4B
Technical Security ManagerFacilities Services40,000$10B

Before GreyMatter, these leaders faced three persistent problems:

  1. Manual, repetitive work left little time for strategic threat analysis.
  2. Fragmented visibility across on-premises, cloud, and identity systems.
  3. Unsustainable cost models — growing data volumes made SIEM ingestion expensive, and unpredictable licensing made forecasting difficult.

The GreyMatter Impact

Agentic AI Eliminated Tier 1 and Tier 2 Work

GreyMatter's agentic AI executes triage, correlation, and enrichment autonomously across the existing tool stack—resolving 85% of alerts for the composite organization without analyst involvement. For the remaining 15%, investigation time dropped 89.5%, with a 6-minute average time to contain.

"With ReliaQuest, I can do the work of 20 people with the work of a nine-person internal team. I can also monitor three times as much, all without having to hire additional people."

CISO Lighting Solutions

Automated Containment Cut MTTR by 75%

GreyMatter executes containment playbooks across the existing stack without analyst handoff. Forrester measured a 75% MTTR reduction. Automated correlation eliminated 80% of false positives before they reached the queue.

"We have 500 alerts per month, and [GreyMatter] is handling around 99% of them."

Deputy CISO Manufacturing

Direct API Integration Eliminated Millions in SIEM Costs

GreyMatter integrates directly with existing tools via API—telemetry is correlated at-source without routing through a centralized SIEM. Organizations consolidated fragmented tool stacks and reduced data storage costs by 33%.

"Because they do direct API calls on everything, I don't have to put everything in a SIEM. From the calculations we've done, we are saving $3.5 million on a yearly basis."
