Corey provides insight into the failed Microsoft 365 login attempts that happen every four seconds
Washington, DC - March 31, 2026: CoreView has announced the general release of Corey, an AI-powered agent designed to help IT teams manage security and maintain visibility into Microsoft 365 environments through natural language. The move comes as organisations face, on average, 140,000 failed Microsoft 365 login attempts every week, each one requiring a judgment call about whether it is routine or an active threat. This means IT teams need to know how to act every four seconds to protect their mission-critical infrastructure.
Corey has been operating in 136 organizations as part of its early access programme. It helps IT teams investigate configuration issues, identify risky permissions, generate governance reports and take corrective actions across the Microsoft 365 tenant through natural language prompts. It operates within CoreView’s governance framework to ensure that actions taken through the AI interface remain traceable and aligned with organisational policies.
The growing footprint of Microsoft 365 has made the need for Corey more urgent. It now underpins operations at more than two million organisations worldwide and its rapid expansion across collaboration, identity, security and compliance services has made administering these environments increasingly complex for IT teams. Corey allows administrators to query tenant data by asking questions, providing much deeper assurance that the organisation’s Microsoft 365 environment is secure.
“Microsoft 365 has become even more mission-critical infrastructure, and the attack surface grows every time an organisation adds a new workload,” said Andrea Sivieri, Chief Product and Technology Officer at CoreView. “Corey doesn't just simplify administration; it brings intelligence and governance to how IT teams operate. That means faster decisions, fewer configuration errors and a security posture that doesn't depend on heroic individual effort.
