Microsoft 365 Audit Tool
Most companies treat Microsoft 365 like a self-cleaning oven. Until audit reveals a “temp-backup-final-v3” SharePoint site from 2019. And—surprise—there’s payroll data shared with external Gmail addresses. And the solution, of course: “IT team will fix it.” 1Security’s Microsoft 365 audit tool fixes that.
Why audit matters?
1Security helps your team work faster and safer in Microsoft 365: ready for AI, protected against breaches, audit-ready for compliance, and prepared to recover quickly from any incident.
Compliance proof
Demonstrable compliance with ISO 27001, SOC 2, GDPR, and HIPAA via audit-friendly dashboards and exportable reports.
Risk & accountability
Lower exposure from oversharing, guests, anonymous links, and orphaned workspaces—while closing ownership gaps and enforcing accountability.
Trusted KPIs
Track risk trends and control coverage with metrics auditors and leadership can rely on.
All-in-one dashboard
One view of inventory, permissions, sensitivity, and activity across SharePoint, Exchange, OneDrive, and Teams.
Smart alerts & answers
Alerts on risky access changes and prebuilt responses to common auditor questions (e.g. externally shared confidential files, Teams without owners, inactive guests).
Evidence & remediation
Export evidence in one click and act immediately with guided fixes like link removals or guest expiration.
Capabilities
Replace portal-hopping with a single, audit-ready view. 1Security’s Microsoft 365 audit tool centralizes inventory and permission context, reveals where sensitive data lives, records change history, and enables governance—so you can act with confidence.
Unified Microsoft 365 inventory
1Security gives you a single view across SharePoint Online, OneDrive for Business, Microsoft Teams, Microsoft Entra (Azure AD), and Microsoft Purview—so you can query sites, teams, channels, groups, sharing links, guests, applications and sensitive content, without time-consuming portal-hopping across Microsoft services in the Microsoft cloud.
Permission & sharing explorer
Explains who can access what and why—direct assignments, groups, and sharing links—without CSV file exports or portal-hopping.
Sensitive data mapping
Maps sensitive data exposure by combining Microsoft Purview sensitivity labels, file metadata, and 1Security’s permission visibility — flagging risks such as ‘Finance folder labeled Confidential with an anonymous link. This supports stronger data governance and data security and helps prevent data breaches by reducing excessive permissions and catching suspicious activity early.
Continuous evidence with change history
Time-stamped evidence of key permission changes, with historical views/“time machine” in development—so your audit trail is defensible.
Risk scoring & prioritized findings
Generates a risk-weighted backlog: public/anonymous links, oversharing, orphaned workspaces, and over-permissive guest access, ocusing on oversharing, anonymous links, orphaned sites, and excessive guest access — with prioritization by sensitivity, business unit, or impact. Sort by impact, sensitivity, or business unit—surface the details you need in a few clicks.
Built-in remediation & governance
Move beyond findings: automations for risky link removal and guest access expiration, plus governance workflows to fix issues and demonstrate closure with an audit trail. Use 1Security to monitor user activity, trigger security investigations, and keep security and compliance aligned—often in a few clicks.
Copilot readiness audit
"Before rolling out Microsoft Copilot, validate labels, link policies, and access boundaries so AI only sees what it should. Identify sensitive data Copilot could surface in SharePoint Online, Exchange Online, OneDrive for Business, and Microsoft Teams, and close gaps first.

Frequently asked questions
Everything you need to know about the product.
How does 1Security improve audit readiness?
1Security provides a single source of truth for audit activities, iincluding permission changes, external sharing, and sensitive data exposure. Evidence packs can be generated in minutes instead of weeks.
Can it track historical audit data?
Yes. 1Security retains audit logs with timestamps and tracks key changes such as group membership, sharing link creation, and permission state history — with time-stamped records for audits.
Does it support Microsoft Copilot readiness?
Yes. 1Security’s audit features reveal sensitive data and oversharing that could be exposed by Copilot, ensuring labels, access boundaries, and policies are aligned before rollout.
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.
