Copilot Security Tool
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.
Why Copilot Security Matters?
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.
Prevent AI Oversharing
Detect files, sites, and sharing paths Copilot could expose before rollout.
Build AI Readiness
Verify permissions, sensitivity labels, and sensitive data across Microsoft 365 so IT can prepare safely for AI adoption.
Stay Compliant
Meet regulatory requirements and prove data protection by tracking exactly who has access to what–and what Copilot can "see."
Save Investigation Time
Replace manual effort with clear context on access, sharing, and sensitive exposure to speed investigations.
Enable Confident Innovation
Deploy Microsoft Copilot and other AI tools without exposing sensitive data or disrupting collaboration.
Protect Sensitive Workflows
Restrict Copilot visibility in Finance, HR, or R&D. Enforce precise access controls so generative AI respects business boundaries.
Capabilities
1Security's Copilot Security Tool reveals what Microsoft Copilot "knows."

"We wanted to roll out Copilot, but compliance stopped us cold. 1Security gave us the proof we needed – mapping Copilot access and protecting organizational data across Microsoft 365 services."
Director of IT Governance, Financial Services Group"We discovered Copilot could access files buried deep in legacy SharePoint sites – things no one had touched in years. 1Security showed our security teams exactly where the exposure of sensitive data was before anything went live."
Information Security Officer, European Research Institute"Our first Copilot test pulled data from a retired project drive. That was the wake-up call. With 1Security, we mapped every AI access path in hours instead of weeks – he fastest security fix we’ve ever achieved."

Frequently asked questions
Everything you need to know about the product and billing.
What is 1Security’s Copilot Security Tool?
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.
How does it prevent AI data leaks?
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.
Can it support AI readiness assessments?
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.
Isn’t Microsoft’s native reporting enough?
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.
Do you support ISO 27001, SOC 2, HIPAA, and GDPR work?
Yes. 1Security maps findings and evidence to common control frameworks, helping organizations demonstrate compliance more efficiently.
Does this replace Microsoft Purview, DLP, or Defender?
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.
Can non-technical stakeholders use it?
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.
Is this only for large enterprises?
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.
Gain visibility. Ensure compliance. Boost productivity.
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.
