Why Microsoft 365 Alerts Matter?

In Microsoft 365, threats rarely announce themselves. A small change in access rights can ripple into major compliance and data security issues. 1Security’s Microsoft 365 Alerts Tool turns those quiet moments into real-time insight helping your team act before incidents happen.

  • Prevent Data Exposure

    Detect and contain oversharing, guest access drift, and misconfigured permissions before they lead to credential theft or data leaks.

  • Simplify Compliance Monitoring

    Map every alert to sensitive data context and regulatory frameworks to stay audit-ready.

  • Enhance Operational Efficiency

    Focus on threats that matter instead of drowning in Microsoft noise.

  • Support AI & Copilot Readiness

    Understand exactly what data Copilot and connected AI tools can access — and who can safely reach sensitive content.

  • Improve Collaboration Security

    Keep users productive while maintaining guardrails on sharing, guest access, and data exposure.

  • Enable Rapid Response

    Centralize alerts, automate remediation, and follow consistent security workflows.

Talk to a Security Specialist

"1Security’s alert correlation changed how we handle risk. The system works alongside Defender signals with sensitivity data, so we instantly know if an alert touches confidential files or compliance-protected content. It’s real insight, not just more notifications"

Compliance Director, Global Consulting Firm

"With 1Security’s Microsoft 365 Alerts Tool, our team finally sees what really matters. Instead of juggling Defender dashboards and admin centers, we have one view that pinpoints real threats and filters out the background noise."

IT Security Manager, Healthcare Organization

"Before 1Security, we relied on default Microsoft alerts and manual, long investigation process. Now, every high-risk incident comes with full context — who, what, and where — so our response time has dropped from weeks to hours."

Frequently asked questions

Everything you need to know about the product.

  • How does 1Security improve Microsoft 365 alerts?

    It consolidates alerts from multiple Microsoft 365 sources, adds permission and data context, and ranks them by severity—so security teams can focus on real threats instead of noise.

  • Does the tool integrate with Microsoft Defender or Purview?

    Yes. 1Security works alongside Microsoft Defender and Microsoft Purview—enriching signals with permission and sensitivity context for a unified view.

  • Can we automate responses to alerts?

    Yes. You can trigger automated workflows to mitigate detected threats—such as disabling a guest, revoking a blocked link, or notifying owners directly in Teams.

  • 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.
