The Architecture Problem
Last quarter, phishing attempts tripled for ReliaQuest customers in the finance industry, and ransomware grew by nearly half. Threat actors known to specifically target financial organizations—APT42, Lazarus, and UNC1069—now move from initial access to persistence in minutes.
Many financial services organizations aren't equipped to keep up. Even with a mature security operation, we consistently see three gaps in finance environments:
Where finance security operations break down today:
Your SIEM doesn't run detection until data is fully ingested and indexed. Every hour of ingest delay is an hour adversaries operate undetected.
Impersonating domains now account for nearly half of all external monitoring alerts in the sector. Credential harvesting, executive impersonation, and brand abuse happen where endpoint and network tools have zero visibility.
Security controls that aren't behaving as configured produce gaps in telemetry. Assets without risk scores create prioritization paralysis when CVEs drop—and finance saw heavy chatter around Microsoft Office RCE, Cisco Unified Communications, and Fortinet FortiOS exploits this quarter.
Meanwhile, AI has removed the skills barrier for executing advanced attacks at scale. The defense layer has to match that speed.

How GreyMatter Defends Financial Institutions
Combined phishing techniques accounted for half of all observed finance-sector activity in Q1 2026. These campaigns operate faster than SIEMs can ingest—by the time data is parsed, indexed, and searchable, adversaries have already moved from initial access to persistence.
GreyMatter Transit runs single- and multi-event correlation on normalized data while it's still streaming, before any of that happens. Partial event sequences are held in temporary state and fire the moment pattern criteria complete.
After detection, you can choose whether to filter, store, or drop the data. You detect in seconds on data you never have to store, while collapsing SIEM ingestion costs.
Impersonating domains accounted for nearly half of all finance-sector DRP alerts in Q1. Adversaries are building brand-spoofing infrastructure to harvest customer and employee credentials at scale, outside any system your SIEM monitors.
GreyMatter Digital Risk Protection (DRP) monitors the open, deep, and dark web for impersonating domains, executive impersonation campaigns, leaked credentials and sensitive data, dark web mentions of your organization, and exploitable vulnerabilities in your external attack surface.
DRP findings directly feed the GreyMatter Agentic Teammates, which can then correlate the external exposure with internal activity, map the campaign to known actor TTPs, and build and deploy relevant detection logic.
Between attacks, your attack surface expands. Every new cloud workload, acquisition, unmanaged endpoint, AI tool, and SaaS application grows the environment defenders in finance must cover.
GreyMatter Discover automatically discovers and deduplicates assets and identities across on-premises, cloud, and hybrid environments to create a unified inventory. It identifies endpoints missing active EDR agents, surfaces cloud misconfigurations from AWS, Azure, and GCP, and enriches vulnerabilities with real-time threat intelligence. Each asset receives an AI-powered threat risk score based on impact and likelihood of exploitation.
When Discover identifies a gap in detection coverage against MITRE ATT&CK, GreyMatter builds and deploys missing logic autonomously. When it finds an unmanaged asset or misconfigured control, applicable automated response playbooks execute directly.
Threat actors targeting financial institutions move from initial access to persistence in minutes. Investigating complex attacks like deepfake Zoom calls requires context from identity, endpoint, network, cloud, and email simultaneously.
Across the entire lifecycle, the Universal Translator uses advanced data mapping (ADM) to normalize every field from any connected technology—Splunk, CrowdStrike, Okta, Microsoft Defender, cloud workloads—into OCSF's unified schema the moment it connects. Correlation happens at ingest, at the individual field level, without centralization.
The IR Analyst Teammate investigates and responds to every triggered alert autonomously—99.4% accuracy, no human intervention. The Threat Intel Analyst maps actor TTPs against finance-sector groups (Clop, DragonForce, APT42, Lazarus, UNC1069) continuously, generating personalized advisory reports. When a new campaign surfaces, the Detection Engineer deploys coverage autonomously.
Customer Spotlight: Donnelley Financial Solutions (DFIN)
DFIN's security team was operating across fragmented visibility—internal asset posture in one set of tools, external threat exposure in another, and investigating across both meant hours of manual context-gathering. They deployed GreyMatter with Discover and DRP to bring both datasets into a single operating layer.
Discover gave them immediate speed-to-context during incidents—AI surfacing current-state asset and configuration details without manual lookup. DRP shifted their external threat posture from reactive to proactive, identifying impersonation attempts, suspected leaked credentials, and suspicious exposure early enough to respond before escalation. Together, the two capabilities reduced noise, accelerated response, and gave the team confidence in both operational decisions and executive reporting.
The measured impact: more than 35 analyst hours reclaimed every week.
"Over the past year, GreyMatter has given us back more than 35 analyst hours every week through AI and automation alone. That's translated directly into faster response times and more capacity for higher-value security work."
Measurable impact with GreyMatter
See It in Your Environment
Your existing EDR, SIEM, identity, cloud, and network tools stay in place. GreyMatter acts as the agentic defense layer across all of them—detecting at source, at storage, and in transit; validating exposure continuously; and monitoring credential threats outside your perimeter.
