ReliaQuest GreyMatter Integrates with Anthropic’s Compliance API, Giving Security Teams Visibility Into Claude Usage Directly Within GreyMatter

ReliaQuest is one of a select group of security technology providers tapped by Anthropic to integrate with this new capability

TAMPA, Fla.--(BUSINESS WIRE)--ReliaQuest, the global leader in Agentic AI cybersecurity, today announced an integration with Anthropic’s Compliance API that brings Claude Enterprise activity logs into the GreyMatter Agentic AI security operations platform. With this integration, security teams can gain visibility into Claude usage directly within GreyMatter—so they can extend the monitoring, investigation, and audit workflows they already run across their enterprise stack to Claude Enterprise.

As organizations deploy Anthropic’s Claude at scale, a growing layer of work activity can sit outside established security operations visibility. Examples include sensitive logins, administrative changes, and configuration updates that may indicate risky behavior or account compromise. When that activity isn’t connected to detection and response workflows, teams may not have the context they need to identify and investigate potential threats.

“Defending the enterprise works best when security teams can use technology to enable the wider business, and AI usage has been a blind spot,” said Brian Murphy, founder and CEO of ReliaQuest. “By integrating Anthropic’s Compliance API into GreyMatter, we’re giving security leaders visibility into Claude Enterprise usage so the companies they protect can leverage more AI securely, using their existing tools and workflows.”

Through the integration, GreyMatter can pull Claude Enterprise activity logs from Anthropic’s Compliance API, including user logins, admin actions, and settings and configuration changes, as an added context layer for security operations.

With Claude Enterprise activity available in GreyMatter, teams can:

• Monitor and investigate Claude Enterprise activity within the same platform used for broader security operations
• Create Claude Enterprise–specific detections based on relevant activity signals
• Utilize GreyMatter Agentic Teammates to understand user usage and autonomously take security actions using natural language, including threat hunts and deeper investigations
• Enrich investigations by bringing Claude Enterprise activity context into GreyMatter casework alongside telemetry from other connected tools
• Correlate signals across the environment to help teams understand how Claude-related activity relates to identity, endpoint, cloud, network, and email events already monitored in GreyMatter
• Execute response actions for enrichment and remediation of threat activity or misuse

GreyMatter already connects across over 250 different security technologies, including SIEM, EDR, cloud, network, and email environments. Adding Claude Enterprise activity logs helps organizations reduce blind spots as AI usage becomes a standard part of day-to-day operations across the enterprise.
