ReliaQuest joins OpenAI program with 3 AI capabilities for cyber defense

Enterprise security teams will gain access to OpenAI's frontier cyber models through ReliaQuest's GreyMatter platform as the two companies partner to counter AI-driven attacks.

Enterprise security teams are gaining access to OpenAI's most advanced cyber capabilities through ReliaQuest's GreyMatter platform, as the company joins the OpenAI Daybreak Cyber Partner Program to counter AI-driven attacks. The program provides ReliaQuest with closer technical collaboration and access to OpenAI's frontier cyber capabilities and models to help enterprises find and patch vulnerabilities faster.

"Cybersecurity is being reshaped by AI on both sides," Brian Murphy, founder and CEO of ReliaQuest, said. "The more we can collaborate, the better we can defend against AI-driven attacks. This partnership with OpenAI helps us move faster in bringing the most advanced Agentic AI capabilities into GreyMatter, so security teams can investigate and respond to threats in minutes."

Under the partnership, ReliaQuest will receive access to advanced OpenAI models and cyber capabilities to support rapid development within the GreyMatter platform. The companies will jointly identify and prioritize high-impact security operations use cases, then collaborate through development, testing and evaluation, and production rollout within ReliaQuest's GreyMatter platform and associated managed workflows. ReliaQuest will contribute frontline security operations expertise and real-world threat insights — including attacker behaviors and investigation patterns observed across enterprise environments — to help shape how AI is applied safely and effectively in security workflows. As a leading AI company in its own right, ReliaQuest will also contribute expertise to help codify standards for safety and abuse prevention, as well as the right controls to monitor and prevent unsanctioned activity.

The announcement comes as attackers increasingly use AI to scale intrusions and bypass traditional defenses, shrinking the window for detection and response. ReliaQuest's GreyMatter platform uses three core capabilities to address this challenge: 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; 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's AI Model Broker Optimizes Cost and Speed

The AI Model Broker within GreyMatter's Agentic Orchestration capability continuously selects the best model for every task based on speed, cost and accuracy — a feature that becomes more valuable as OpenAI's frontier models join the mix. This allows security teams to run investigations and execute response across their entire tech stack in plain language without requiring any tool expertise, according to ReliaQuest. The company, founded in 2007, has placed itself at the center of the emerging agentic AI cybersecurity category, where autonomous systems handle complex security workflows that previously required specialized analysts. The Universal Translator component addresses a persistent pain point for enterprise security teams: the need to normalize data from dozens of vendors without moving or centralizing it.

Enterprise Security Faces an AI Arms Race

The partnership highlights a broader shift in cybersecurity: both attackers and defenders are racing to deploy AI. Adversaries are using generative AI to automate reconnaissance, craft more convincing phishing campaigns and accelerate the speed of intrusions, according to industry reports. For enterprise security teams, the shrinking detection window means tools that can investigate and respond in minutes — rather than hours or days — are becoming essential. ReliaQuest's integration with OpenAI positions GreyMatter to address this gap, though the company faces competition from other cybersecurity vendors incorporating large language models into their products, including CrowdStrike and Palo Alto Networks, both of which have announced AI-powered security features over the past year.

For investors, the partnership shows deeper integration between frontier AI models and enterprise security infrastructure. ReliaQuest, as a private company, does not disclose financial metrics such as annual recurring revenue or customer count. However, the broader cybersecurity market is projected to exceed $300 billion by 2027, according to industry estimates from firms such as Gartner and IDC. Publicly traded peers such as CrowdStrike, which trades at about 25 times forward sales, and Palo Alto Networks are also investing heavily in AI capabilities, making this an increasingly competitive segment of the security market. The OpenAI partnership gives ReliaQuest a potential edge in access to frontier models, though the long-term impact will depend on how effectively the company can translate that access into differentiated product features.
