ReliaQuest launches GreyMatter Attack AI-driven red‑team platform

ReliaQuest, a global cybersecurity firm, introduced GreyMatter Attack, an agentic AI capability within its GreyMatter platform. The solution enables security teams to conduct AI‑driven red teaming, generate visual attack‑path maps, and receive prioritized remediation recommendations.

Users can issue natural‑language prompts based on a user identity, an initial access point, or a known threat‑actor technique; the platform then produces attack‑path visualizations and feeds findings into ReliaQuest’s proprietary Agentic Teammates, which can automatically create new detections and initiate response actions. The company will showcase GreyMatter Attack at Black Hat USA 2026. “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.
