Microsoft 365 is where your business runs—and where your risk lives.

Every day, organizations generate a flood of unstructured data across SharePoint, OneDrive, Teams, and Exchange. That data often includes your most sensitive content: contracts, employee records, intellectual property, customer personally identifiable information, and more. But in too many environments, it’s poorly labeled, widely over-shared, and increasingly exposed to powerful AI tools like Microsoft Copilot.

Rubrik’s latest Data Security Posture Management (DSPM) release helps you regain visibility and enforce control over that data—before it becomes a liability. Indeed, new AI-driven capabilities help security teams reduce data exposure and overshared access risk, enforce policy, and prepare for safe Copilot adoption—at scale.

Why Microsoft 365 Needs a New Kind of Data Security

Most organizations struggle to answer basic questions about their M365 data:

  • What sensitive content do we have and where is it stored?

  • Who has access and how did they get it?

  • Is it properly labeled and protected, especially from AI tools like Copilot?

Traditional tools aren’t built to answer these questions at scale. Manual audits and native controls like Purview can’t keep up with the pace of collaboration, growth, and AI adoption.

Rubrik DSPM changes the game.

What’s New in Rubrik DSPM for Microsoft 365

Rubrik DSPM has already helped customers discover sensitive data, surface exposures, and apply data governance controls across M365. Now, we make that process faster, smarter, and more scalable—with powerful new capabilities that move you from awareness to action.

Automated MIP Labeling: Rubrik now automatically applies Microsoft Information Protection (MIP) labels based on AI-driven classification—no user involvement needed. That means:

  • You can enforce consistent data protection policies, even if users skip or mislabel files.

  • You’ll be ready for Copilot with accurate labeling of thousands of documents, helping to ensure AI tools only see what they should.

AI-Powered Document Classification: Rubrik uses machine learning to identify documents by their business context—contracts, SLAs, resumes, financials, and more. This helps:

  • Prioritize what matters most and enforce policy based on business value.

  • Reduce reliance on manual tagging, rule creation, or content owners.

Smarter Access Governance

New Data Access Governance (DAG) capabilities give teams a clear view of:

  • Who has access to sensitive files—with details on direct, group, and role-based permissions.

  • How access was granted, with new tools to revoke public, org-wide, or user-level access in bulk.

  • Custom policy alerts, like flagging external users accessing PII or non-HR teams accessing employee data.

Why It Matters: With Rubrik DSPM, Microsoft 365 customers can finally operationalize security—not just observe risk, but reduce it. You can:

  • Protect sensitive data from insider threats, misconfiguration, and AI exposure.

  • Automate remediation of oversharing and mislabeling across millions of files.

  • Align data governance to business priorities, using document types and identity context to enforce smarter controls.

  • Cut investigation time when incidents occur—with clear mapping of data access and risk.

And you can do it without adding headcount, disrupting workflows, or waiting for an attack to happen.

Rubrik DSPM for Microsoft 365: Built for the Age of AI

As AI tools like Copilot become core to how teams collaborate and create, the risk of data leakage is growing fast. Rubrik DSPM V2 helps ensure your data security is ready—with the classification, labeling, and access controls you need to keep sensitive information protected.

With Rubrik, you don’t just back up your Microsoft 365 data—you lock it down, classify what matters, and take action before attackers (or AI) can do damage.
