About the company
As organizations increasingly adopt AI-powered productivity tools within Microsoft 365, the risk of uncontrolled data access and permission sprawl has become a critical security challenge. 1Security addresses this with a comprehensive SaaS platform that delivers real-time visibility, automated remediation, and intelligent data protection across the entire M365 ecosystem.
The platform consists of three integrated modules. Visibility provides an interactive access map for instant permission audits. Automation enables mass-scale rightsizing of access rights, time-limited permissions, and intelligent alerts. Sensitivity leverages AI-powered classification to detect and protect sensitive data across SharePoint, OneDrive, and Teams - going beyond traditional keyword-based DLP solutions.
With 345 million M365 paid users globally and growing AI adoption creating new security vectors, 1Security is positioned to become a foundational layer for enterprise security in the Microsoft ecosystem.
