1Security Copilot Exposure is a data security posture management tool designed to assess and manage risks associated with Microsoft 365 Copilot deployment. The product identifies which files and data Microsoft Copilot can access based on existing permission structures across SharePoint, OneDrive, and other Microsoft 365 services. The tool addresses oversharing risks by identifying files shared with "Everyone" within an organization that could become accessible to Copilot queries. It detects sensitive data exposure including HR records, salary information, and legal documents with loose access controls. The platform maps stale permissions from old access rights and identifies guest access loopholes where external partners or vendors might access internal files through AI tools. 1Security provides visibility into data risks before Copilot licenses are assigned to employees. It generates permission graphs showing exact file access rights across users and identifies sensitive data containing credit cards, salaries, or personal information. The tool enables administrators to remove company-wide sharing links, clean up external guest access, and review user access rights without manual searches or complex scripts. The platform includes automated safety checks with alerts when sensitive files become exposed to too many users. It maps findings to compliance frameworks including ISO 27001, SOC 2, HIPAA, and GDPR. The interface provides plain-language reports for non-technical stakeholders including compliance, legal, and business teams.
