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.
