Introduction
ReliaQuest, recognized as a global leader in Agentic AI cybersecurity, has unveiled GreyMatter SIEM‑Less, a new offering designed to help enterprise security teams accelerate threat detection while gaining greater control over where security data is stored. The platform allows organizations to keep telemetry in a cost‑effective repository they own, query it in seconds from any location, and generate reports on demand—all without the expense and constraints tied to conventional SIEM systems. ReliaQuest will showcase GreyMatter SIEM‑Less at Black Hat USA 2026, highlighting its relevance amid rising AI‑driven attacks and increasingly dispersed telemetry landscapes.
The Need for SIEM‑Less
As AI‑powered attacks accelerate and enterprise telemetry becomes spread across clouds, endpoints, SaaS applications, and hybrid infrastructures, traditional security operations architectures are being re‑evaluated. Legacy SIEM platforms require telemetry to be collected, indexed, parsed, and stored before any detection can occur, introducing latency that adversaries can exploit. Moreover, consolidating all data into a single, centralized SIEM is increasingly difficult to justify from both cost and performance perspectives. Security teams now need an approach that detects threats before data reaches storage, provides full ownership of telemetry, and enables centralized querying across diverse environments without incurring prohibitive expenses. GreyMatter SIEM‑Less was engineered to satisfy these evolving operational demands.
What is GreyMatter SIEM‑Less?
GreyMatter SIEM‑Less extends ReliaQuest’s existing Agentic Defense platform, GreyMatter, by redefining how security telemetry is managed throughout its lifecycle. Rather than forcing data into a monolithic SIEM for indexing, the solution allows organizations to retain telemetry in a repository they control—whether that is a data lake, object storage, or another cost‑effective store. From that repository, analysts can query the data in seconds, run saved searches, produce reports, and conduct investigations or threat hunts, all while preserving core response actions such as IP blocking, file‑hash banning, and containment initiation. The result is a detection‑first architecture that retains the analytical power of a SIEM without its traditional drawbacks.
How It Works: Detection, Query, and Response
At the heart of GreyMatter SIEM‑Less is the ability to generate detections within seconds, whether the telemetry resides at its source, in storage, or while in transit. The platform’s Detection at Source/Storage/In‑Transit capability catches threats before they are ever indexed or parsed, drastically reducing the time between activity and alert. Once telemetry is stored, analysts interact with it using natural language through the Universal Translator, which automatically normalizes data from any vendor without requiring centralization. This enables saved queries, ad‑hoc searches, and on‑demand reporting directly from the GreyMatter console. Crucially, the same interface supports investigative workflows and response actions—analysts can hunt threats, execute containment, and coordinate remediation without switching tools, creating a unified operational loop that minimizes performance‑cost tradeoffs.
Benefits: Flexibility, Cost Savings, and Control
By decoupling detection from the expensive indexing and storage processes of legacy SIEMs, GreyMatter SIEM‑Less delivers several tangible advantages. First, organizations retain complete control over where their telemetry lives, allowing them to choose the most economical storage option that meets compliance and retention requirements. Second, because detection occurs before or alongside storage, latency is dramatically reduced, enabling faster response to agentic AI attacks that evolve in real time. Third, the solution’s centralized querying capability means analysts can search across heterogeneous environments from a single pane of glass, eliminating the need to pivot between multiple tools. Finally, the natural language interface lowers the barrier to entry, empowering any defender to perform sophisticated searches, investigations, and hunts without deep expertise in query languages or proprietary platforms. Collectively, these benefits translate into lower operational costs, improved agility, and a stronger security posture.
Leadership Commentary
Brian Murphy, founder and CEO of ReliaQuest, framed the launch within a broader industry shift: “We are in the middle of the great re‑architecture of cybersecurity. The most advanced security teams are rethinking how they store data, how they detect threats, and how quickly they can take action to stay ahead of agentic attacks. GreyMatter SIEM‑Less provides the optionality and modularity they need to build the fastest, most accurate, and cost‑efficient architecture possible.” Murphy’s remarks underscore that the solution is not merely an incremental improvement but a strategic enabler for organizations seeking to redesign their security operations around speed, precision, and fiscal responsibility. His vision aligns with the growing recognition that static, monolithic SIEMs are ill‑suited for the dynamic, AI‑accelerated threat landscape.
Deployment and Demonstration at Black Hat USA 2026
ReliaQuest will demonstrate GreyMatter SIEM‑Less live at Black Hat USA 2026, inviting attendees to experience the platform’s capabilities firsthand. The demonstrations will take place at the ReliaQuest booth (#2139)**, where security professionals can and observe detection within the generate reports, and take containment. For those who prefer a deeper dive into briefings can be scheduled via the Quest.com/black-hat/. This provides an opportunity to see how detection, querying, investigation, and response unfold in real time using natural language commands. Interested parties can also arrange a briefing by visiting https://reliaquest.com/black-hat/. By showcasing the solution at one of the premier cybersecurity events, ReliaQuest aims to illustrate how enterprises can transition from legacy SIEM constraints to a more adaptable, AI‑driven security posture.
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 using plain language, without requiring specialized tool expertise. GreyMatter achieves this through three core capabilities:
- Universal Translator – automatically normalizes telemetry from any vendor without the need for data centralization.
- Detection at Source, at Storage, or in Transit – identifies threats where data resides or as it moves, before it is ever indexed, parsed, or stored.
- Agentic Orchestration – combines a natural language operating layer, multiple autonomous agentic systems, and an AI Model Broker that continuously selects the optimal model for each task based on speed, cost, and accuracy.
Through these capabilities, GreyMatter enables organizations to re‑architect their security environment for heightened speed, efficiency, and cost control. ReliaQuest has been advancing security innovation since 2007, continually evolving its offerings to meet the challenges posed by emerging threats.
Conclusion
GreyMatter SIEM‑Less represents a pivotal step toward a more flexible, detection‑centric security operations model. By removing the traditional bottlenecks of SIEM platforms—namely, mandatory indexing, centralized storage, and associated latency—the solution empowers enterprises to detect AI‑driven threats faster, retain telemetry on their own terms, and conduct investigations and responses from a single, intuitive interface. As organizations continue to grapple with distributed data estates and increasingly sophisticated attacks, the ability to query, analyze, and act on telemetry in real time, without prohibitive cost, will become a decisive competitive advantage. ReliaQuest’s launch at Black Hat USA 2026 signals that the future of security operations lies not in bigger, more expensive SIEMs, but in smarter, agentic‑driven architectures that put speed, control, and efficiency at the forefront.
