GreyMatter SIEM-Less
Detect where data lives. Store what you need.
Attacks move in minutes, and data lives everywhere — across dozens of technologies, multiple clouds, and geographies. The traditional way of centralizing every data point into a SIEM is no longer realistic. Data has to be indexed, parsed, and stored before a single detection can run against it. Most teams can't get every source in, so they end up with blind spots — and the ones who try watch the bill skyrocket.
GreyMatter SIEM-Less gives you the benefits of a SIEM without the tradeoffs.
Faster Detection
Multi-event correlation in transit and at the source — before data is ever indexed, parsed, or stored.
Full Visibility
Connect to every source and see it in GreyMatter without having to store it first.
Lower Cost
Keep only what you need instead of ingesting everything into one expensive repository.
Architectural Control
Your storage, your terms — plug in, unplug, and reshape the architecture as needs change.
Detection, Investigation & Response — Without Centralizing First
GreyMatter SIEM-Less picks data up where it already lives — at the source, or in motion through Transit — and runs detection before it is ever indexed, parsed, or stored. Investigations and hunts reach out to the data wherever it sits rather than waiting for it to arrive. You store only what you need, in storage you own, and query it on demand from one place.
Collect & normalize
GreyMatter Transit collects from your data sources and the Universal Translator normalizes every field to OCSF on the way through.
Detect without storage
Multi-event correlation runs in transit, and detection runs at the source — firing alerts in GreyMatter without waiting on indexing or storage.
AI investigates & responds
Alerts are investigated autonomously by the Agentic Teammates, which enrich, reach a disposition, and execute response actions.
Filter, route, index & store
Keep what you need, drop what you don't. GreyMatter Index writes data to your object storage in a format built for fast retrieval.
Query, hunt & report
Search, hunt, investigate, and build reports against stored data on demand — from inside GreyMatter, no SIEM underneath.
Four ways teams put GreyMatter SIEM-Less to work
The power of a SIEM, without a SIEM
Run detection, investigation, response, search, and reporting from one window — with data in storage you own instead of a licensed repository.
Detect before data ever lands
Catch multi-event patterns as data moves and at the source — firing in seconds instead of waiting on ingest, parsing, and indexing.
Detect and route before the bill
Send high-volume sources through Transit for detection, then drop or store cheaply — full coverage without paying to ingest every event.
Cover what never made it in
Bring detection to sources you could never justify centralizing — OT, network telemetry, medical devices, and everything left outside the SIEM.
Proven Defense
$2–$4 Back for every $1 spent
Re-architect your security environment for speed, efficiency, and cost control—reducing SIEM ingestion costs, eliminating per-token charges, and consolidating overlapping technologies. Customers get more done with the existing teams and technologies they have saving on operational costs.
One Price, Unrestricted Use.
No per-alert, per-token, or per-investigation charges. Flat, predictable pricing means costs stay controlled as usage scales. The AI Model Broker controls AI cost at the infrastructure level, so lighter models run where sufficient and premium models are reserved for tasks that require them.
Agentic Defense for every Industry
About ReliaQuest
ReliaQuest is an agentic AI cybersecurity company whose platform, GreyMatter, serves as the Agentic Defense for the enterprise—defending organizations against AI-accelerated attacks. Any defender can harness that AI to detect threats, run investigations, execute response, and hunt across their entire tech stack in plain language without requiring any tool expertise.
GreyMatter makes this possible through three capabilities: the Universal Translator, which automatically normalizes telemetry across any vendor without data centralization; Detection at Source, at Storage, or in Transit, which catches threats where data lives or as it moves before it is ever indexed, parsed, or stored; and Agentic Orchestration, which combines a natural language operating layer, multiple autonomous agentic systems, and an AI Model Broker that continuously selects the best model for every task based on speed, cost, and accuracy.
GreyMatter enables organizations to re-architect their security environment for speed, efficiency, and cost control—and customers see 2 to 4 back for every $1 they spend. Trusted by 1,300+ enterprises, ReliaQuest has been making security possible since 2007.
