ReliaQuest Introduces GreyMatter Attack, Enabling AI-Driven Red-Teaming and Attack Path Mapping

New agentic capability enables natural-language AI-driven red teaming, visual attack path mapping, and prioritized remediation recommendations – so security teams can find and close exposures before attackers know they’re there

TAMPA, Fla.--(BUSINESS WIRE)--ReliaQuest, the global leader in Agentic AI cybersecurity, today announced GreyMatter Attack, a new agentic capability within the GreyMatter platform that helps security teams use powerful frontier AI models to move faster than the adversaries targeting them. GreyMatter Attack allows organizations to proactively identify and validate exposures by mapping attack paths across their environment, helping them go on the offensive against agentic attacks. ReliaQuest will demonstrate GreyMatter Attack during Black Hat USA 2026.

AI has given attackers three main advantages: speed, scale, and the removal of the skill barrier—enabling them to move faster, target more organizations at once, and execute sophisticated attacks with less expertise. ReliaQuest’s agentic defense approach, now with GreyMatter Attack, brings those same advantages to defenders so they can operate with greater speed across complex, hybrid environments, utilizing the most powerful frontier models already within GreyMatter.

With GreyMatter Attack, defenders can prompt the platform in natural language—starting from a user identity, an entry point, or even a known threat actor technique—and return a visual attack path that highlights every plausible gap along with prioritized recommendations to close exposure. Defenders can go even further with GreyMatter Attack by executing the generated attack path directly against their environment at the push of a button for validation. Findings can be fed directly back into the proprietary ReliaQuest Agentic Teammates to harden the environment by autonomously writing new detections, taking response actions, and implementing other security controls.

"Powerful frontier AI hasn't just created new ways for attackers to exploit organizations, it's also given defenders a speed advantage they've never had before," said Brian Murphy, founder and CEO of ReliaQuest. "GreyMatter Attack lets security teams put that power to work. Using the knowledge only defenders have about their own organizations, teams can simulate threats, test attack paths against their real environments, and close gaps before an attacker can find them."

The GreyMatter platform already serves as the Agentic Defense for the enterprise, helping security teams detect threats, run investigations, execute response, and hunt across their entire tech stack in plain language without requiring tool-specific expertise or forcing data centralization.

Black Hat attendees can see live demonstrations at the ReliaQuest booth #2139 or request 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.
