Microsoft Copilot doesn’t leak data–it just borrows it from very unexpected places. AI makes Microsoft 365 smarter, but when access is messy, it follows the mess. 1Security shows what Copilot can access across Microsoft 365 and where exposure risks exist–so you can deploy AI with confidence.
1Security helps your team work faster and safer in Microsoft 365. AI should be an accelerator, not a risk multiplier–1Security ensures Microsoft Copilot learns only from the right content for each of its users while maintaining compliance and strong access controls.
Detect files, sites, and sharing paths Copilot could expose before rollout.
Verify permissions, sensitivity labels, and sensitive data across Microsoft 365 so IT can prepare safely for AI adoption.
Meet regulatory requirements and prove data protection by tracking exactly who has access to what–and what Copilot can “see.”
Replace manual effort with clear context on access, sharing, and sensitive exposure to speed investigations.
Deploy Microsoft Copilot and other AI tools without exposing sensitive data or disrupting collaboration.
Restrict Copilot visibility in Finance, HR, or R&D. Enforce precise access controls so generative AI respects business boundaries.
1Security’s Copilot Security Tool reveals what Microsoft Copilot “knows.” It maps organizational data exposure across Microsoft 365 services–including SharePoint, Teams, OneDrive, and connected apps–showing where AI models could surface sensitive data, who’s affected, and how to fix issues before they go public. These key features give security teams actionable recommendations and audit-ready visibility.
See every file, folder, and SharePoint site Copilot can access - in total or from a user’s perspective, mapped through Microsoft Graph.
Combine Microsoft Purview insights with 1Security’s permission visibility to pinpoint which sensitive data Copilot might surface in generated responses.
Receive alerts when copilot access expands, new users join, or sensitive files are shared – so security controls stay ahead of change.
Track where Copilot access creates risk and support enforcement with access clean-up, guest expiry, and risky link removal–working alongside Purview/DLP.
Automate risky link removal, guest expirations, and conditional access enforcement to reduce exposure.
Generate exportable reports aligned with data security frameworks, integrating and expanding on Microsoft Purview insights for complete visibility and compliance context.

Everything you need to know about the product.
It’s a Microsoft 365 add-on that reveals what Microsoft Copilot could access, how it’s shared, and where exposure risks exist–giving a unified view of access, sensitivity labels, and permission models.
1Security maps Copilot access across Microsoft 365 services, correlating permissions with sensitive data labels and data protection rules. When new users or guests gain visibility or sharing links change, it sends real-time alerts on risky changes–helping reduce the chance of leaks.
Yes. 1Security analyzes permissions, labels, and exposure paths to verify controls and identify risks for safe Copilot adoption. It identifies data security risks and creates actionable recommendations so your organization can adopt Copilot safely and meet privacy standards set by the European Union.
Native tools provide valuable data but are fragmented across SharePoint Online, Exchange Online, Entra ID, Teams, Purview and Graph API. 1Security consolidates inventory, permissions, sensitivity, and activity signals into one place with audit-ready reporting.
Yes. 1Security maps findings and evidence to common control frameworks, helping organizations demonstrate compliance more efficiently.
No. 1Security complements Microsoft’s ecosystem by adding context and workflows — the who, what, where, and why — and pairing it with remediation and compliance-ready evidence.
Yes. Plain-language reports and read-only views make it easy for compliance, legal, and business stakeholders to see the evidence behind findings without needing admin rights.
No. While designed for complex environments, 1Security is equally valuable for mid-sized organizations running Microsoft 365 or Office 365 that need strong visibility into access, activity, and compliance.
Stop guessing who has access to your sensitive data. With 1Security, you gain the visibility, automation, and confidence needed to protect your Microsoft 365 environment.
