ReliaQuest, the AI cybersecurity company behind GreyMatter, announced expanded AI initiatives with Anthropic, the AI safety company and creator of the Claude family of models, aimed at accelerating the development and deployment of AI for enterprise cyber defense.
The collaboration brings Anthropic’s Claude core family of models into the ReliaQuest GreyMatter platform, which is used by some of the world’s largest organizations to detect, investigate, and respond to cyber threats at machine speed. Through the partnership, GreyMatter customers will gain access to advanced AI capabilities designed to strengthen enterprise cyber defenses.
ReliaQuest has also joined Anthropic’s Project Glasswing and is using Mythos within its own systems for defensive cybersecurity applications. Through its participation in Project Glasswing, ReliaQuest will gain shared insights into how emerging AI models may be leveraged by threat actors.
“We are at a defining moment for cybersecurity,” said ReliaQuest founder and CEO Brian Murphy. “AI is changing what attackers can do. It has to change what defenders can do too. Our work with Anthropic means our customers will have more access to frontier AI models deeply integrated into GreyMatter — so they can move faster and respond with greater confidence than the adversary.”
The expanded integration of Claude builds on an existing relationship between the two companies. GreyMatter already uses Claude’s advanced reasoning capabilities for complex security operations tasks, including alert triage, threat investigation, and analysis of sophisticated multi-stage attacks.
ReliaQuest was also among an initial group of security vendors recently selected to integrate with Anthropic’s compliance API — enabling authorized Claude activity data to be brought into GreyMatter. This allows enterprise security teams to monitor, detect, and respond to Claude usage in the same manner as other enterprise applications operating within their environments.
Claude models have been incorporated into GreyMatter since the platform’s early development. They are among more than 20 AI models supporting GreyMatter’s model-agnostic agentic systems through its AI Model Broker. The broker automatically determines which model is best suited for an individual task based on factors including speed, accuracy, and cost.
The latest initiatives further strengthen the collaboration between ReliaQuest and Anthropic while expanding the capabilities GreyMatter can provide to enterprise customers as Anthropic continues advancing its AI technology.

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.
ABOUT ANTHROPIC
