ReliaQuest, the global leader in Agentic AI cybersecurity, has introduced GreyMatter SIEM-Less, a new solution designed to help enterprise security teams improve detection speed while giving them greater flexibility over where security data is stored. The platform enables organizations to retain telemetry in a more cost-effective repository they control, query it in seconds from any location, and generate reports on demand—without the expense and limitations associated with traditional SIEM platforms. ReliaQuest will demonstrate GreyMatter SIEM-Less during Black Hat USA 2026.
As AI-driven attacks continue to accelerate and enterprise telemetry becomes increasingly distributed, organizations are re-evaluating the way security operations are architected. Security teams require an approach that supports rapid detection before data reaches storage, provides complete control over telemetry, and enables centralized querying across diverse environments. GreyMatter SIEM-Less was developed to address these evolving operational requirements.
GreyMatter functions as the Agentic Defense platform for enterprises, allowing security teams to detect threats, investigate incidents, perform threat hunting, and coordinate response activities across their technology environments. GreyMatter SIEM-Less extends these capabilities by transforming how security telemetry is managed throughout its lifecycle. The solution delivers detections within seconds while preserving essential security operations capabilities—including search, investigations, reporting, and response—with improved flexibility and reduced operational costs.
“We are in the middle of the great re-architecture of cybersecurity,” said Brian Murphy, founder and CEO of ReliaQuest. “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.”
As security operations evolve, enterprises are increasingly seeking scalable and flexible methods for managing telemetry. Traditional SIEM platforms have historically served as the foundation of security operations, but they require telemetry to be collected, indexed, parsed, and stored before detections can occur, introducing delays. With security data now spread across a growing number of environments, consolidating all telemetry into a single platform is becoming more difficult to justify from both a cost and performance perspective. Organizations are instead looking to detect threats where data originates or while it is in transit, selectively retain only the telemetry they need, and maintain critical capabilities such as saved searches, reporting, investigations, and long-term data retention without incurring the traditional costs of centralized SIEM architectures.
GreyMatter enables analysts to interact directly with stored telemetry using natural language. Security teams can execute searches, save queries, generate reports, and perform investigations or threat hunts while maintaining response capabilities from the same console, including blocking IP addresses, banning file hashes, and initiating containment actions. This unified approach combines telemetry management, detection, investigation, and response into a single operational workflow while minimizing the tradeoffs typically associated with performance and cost.
Attendees at Black Hat can experience live demonstrations of GreyMatter SIEM-Less at the ReliaQuest booth (#2139) or schedule a briefing at https://reliaquest.com/black-hat/.

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. ReliaQuest has been making security possible since 2007.
