GreyMatter Attack
Find every attack path before the opponent does.
Attackers are using AI to find the openings in your environment. Frontier and open-source models gave them three things at once — speed, scale, and the removal of the skills barrier. The fastest data exfiltration ReliaQuest observed in 2025 took just 6 minutes.
GreyMatter Attack lets defenders use that same AI to run attacks in their own environment, find the gaps, and close them before an attacker ever shows up.
How It Works
GreyMatter Attack is an agentic capability that maps attack paths across your environment. Choose a pre-built attack campaign or create your own in natural language. It returns a visual attack path showing every gap along the way, with prioritized recommendations to close each exposure. And when you need proof, execute the attack against your live environment at the push of a button.
Choose your starting point
Tell GreyMatter how you want to attack your environment — in plain language.
Agentic AI maps the paths
AI reasons across a mapped model of your environment — identities, permissions, exposures, controls — to trace every route an attacker could take.
Attack to prove it
Push the button and execute the technique against the live environment — confirming what is real, not theoretical.
Feed it to your Agentic Teammates
Findings flow into the platform — Teammates build detections, harden controls, and hunt for paths already used.
Where to Start
Test a single identity
Point it at one user — a VIP, an overly privileged account, a service identity — and see how far an attacker could get if those credentials were compromised.
Simulate a named threat actor
Emulate a specific adversary using GreyMatter's threat intelligence — the real tactics of groups targeting your industry. No red team expertise required.
Validate a pen test report
Upload findings from a recent penetration test and see how those techniques would play out today — which controls hold, and which gaps are still open.
Start from a GreyMatter insight
Launch straight from what the platform already surfaced — an exposure, a detection gap, or a triggered alert — and see what an attacker could do with it.
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.
