GreyMatter: Agentic Defense for Manufacturing
Autonomous detection, investigation, and containment across IT and OT. Under 5 minutes. No data centralization required.
From telemetry event to validated detection via GreyMatter Transit.
Mean time to contain confirmed threats via Automated Response Playbooks.
SIEM ingest savings through detection at-source and in-transit.
The Architecture Problem
Attacks against manufacturing companies spiked 264% in Q1 2026—the largest jump we saw in any customer sector. Exfiltration happens in as little as 6 minutes, while a single hour of unplanned downtime costs $50K–125K.
Even with a mature security operation, we consistently see four gaps in manufacturing environments:
Where manufacturing security operations break down today:
SIEMs don't run detection until data is fully ingested and indexed—a process that can take hours. OT telemetry is often too expensive to centralize, so it never gets detected on at all.
Credential harvesting accounted for more than half of all external monitoring alerts in manufacturing last quarter. Initial access brokers sell VPN and RDP access to manufacturing firms on criminal forums daily.
Many industrial assets can't be patched, operate on unsupported systems, and exist outside traditional security visibility. Open ports on OT systems more than doubled this year.
Security teams pivot between disconnected consoles—spending 40+ minutes per investigation correlating threats that move from a compromised VPN credential through Active Directory into a PLC.
AI has removed the skills barrier for executing these attacks at scale. The defense layer must match that speed.

How GreyMatter Defends Manufacturing Environments
Play and Akira use living-off-the-land binaries—PowerShell, native Windows processes—that look legitimate as individual events. The attack only becomes visible as a multi-event sequence.
GreyMatter Transit runs single-event and complex multi-event correlation logic on data before it's parsed, indexed, or stored. Partial event sequences are held in temporary storage while subsequent events complete a pattern.
After detection, filter the data, route it to storage, or drop it entirely. Transit extends detection coverage into OT data streams that would have previously gone entirely undetected—achieving 40–60% SIEM ingest savings while increasing coverage.
More than half of all manufacturing external monitoring alerts this quarter were credential exposure—adversaries harvesting access they sell on criminal forums before ransomware deployment.
GreyMatter Digital Risk Protection (DRP) continuously monitors criminal forums, dark web marketplaces, and attacker infrastructure for VPN/RDP access listed for sale, engineer credentials exposed in breaches, impersonating domains targeting your brand, and supplier exposure across your attack surface.
DRP findings feed the GreyMatter Agentic Teammates. The Threat Intel Analyst maps them against known actor TTPs (Play, Akira, NightSpire), and the Detection Engineer builds and deploys coverage for the specific access path before exploitation occurs.
Open-port alerts from OT systems more than doubled this year, and 30,000+ Modbus/ICS devices are discoverable on Shodan.
GreyMatter Discover maps your external attack surface—open ports on OT systems, unmanaged industrial assets, VPN/RDP exposure into plants—and applies risk scores based on operational impact. It validates that security controls are producing telemetry your detections depend on, identifying silent log sources and misconfigured tools before attackers exploit the gap.
Play's kill chain spans five tool boundaries on the IT side before it touches OT. Most SOC teams don't have analysts who speak both languages.
The OT Engineer Teammate operates across IT and OT simultaneously—investigating alerts from OT solutions (Armis, Nozomi, SCADA historians), correlating them with IT identity, endpoint, and VPN activity, and surfacing the full cross-boundary attack chain as a single investigation. It tags alerts by site and asset criticality, so a PLC anomaly at a high-criticality production line escalates differently than a test environment.
The OT Engineer investigates autonomously but defers containment in production environments to human approval. Full correlated investigation with a recommended response—executed only when your OT team confirms.
Customer Spotlight: Signify
Signify—a multi-billion-euro lighting manufacturer with 30,000+ employees across 70 countries—managed IT, cloud, and manufacturing environments through separate tools, with no unified visibility across OT and cloud. Continuous M&A activity meant new technologies needed to integrate fast without slowing security operations.
GreyMatter unified EDR, firewall, network, cloud, and OT technologies into a single operating layer. Automated containment replaced reactive triage.
The measured impact: 81% reduction in alert noise, 1,000 hours saved annually, and 75% lower mean time to resolve.
"We had visibility to the IT workplace, but the business doesn't exist solely there. There's heavy dependence on different clouds, different services, operational technologies—still needing to be combined in one platform. And that's now been done with GreyMatter."
Measurable impact with GreyMatter
See It in Your Environment
Your existing EDR, SIEM, identity, cloud, network, and OT tools stay in place. GreyMatter acts as the agentic defense layer across all of them—normalizing at the field level, detecting in transit, validating exposure continuously, and monitoring credential threats outside your perimeter.
