Generative AI is rewriting the rules of enterprise productivity — and the rules of enterprise risk. As AI tools move from pilot programs into core workflows, security teams face a question that wasn't on most roadmaps two years ago: How do you enable AI-powered innovation while helping protect sensitive data in the process?
A report from Microsoft offers a detailed look at how the industry is answering that question. The 2026 Microsoft Data Security Index — a Microsoft-produced global research report — draws on responses from more than 1,700 security leaders worldwide to identify the priorities separating organizations that are getting ahead of AI risk from those still playing catch-up.
Three imperatives emerged in the report.
Imperative 1: Break down the silos
For many security teams, one of the biggest obstacles to effective data governance isn't a lack of tools — it's too many of them. Security leaders in the report cited poor integration, lack of a unified view across environments and fragmented dashboards as their top barriers to visibility and control. With AI accelerating the volume and velocity of data flows, those blind spots are growing harder to ignore.

According to the report, surveyed organizations are responding by consolidating onto unified platforms that provide continuous oversight across cloud, SaaS and on-premises environments. More than 80% of surveyed organizations are now implementing or developing Data Security Posture Management (DSPM) strategies — a discipline that helps teams discover, classify and protect sensitive data at scale. Microsoft Purview provides this capability, integrating data discovery, classification and protection in a single platform built to keep pace with AI-powered data environments.
Imperative 2: Build AI-specific controls — now
Generative AI tools are already changing the shape of security incidents. According to the report, 32% of surveyed organizations have experienced data security incidents involving generative AI tools. The response has been swift: nearly half (47%) of surveyed security leaders are now implementing generative AI-specific controls, up 8 percentage points from the prior year.
The goal isn’t to block AI adoption — it’s to help ensure both unsanctioned and sanctioned AI tools are used responsibly. That means monitoring how data is accessed and shared in AI-powered workflows and enforcing guardrails that help reduce unauthorized exposure without throttling productivity.
Microsoft Purview Data Loss Prevention and Microsoft Defender for Cloud Apps help organizations identify, investigate and respond to risky AI behaviors — flagging policy violations, anomalous usage patterns and unsafe outputs as they emerge.
Imperative 3: Use AI to defend against AI-era threats
Perhaps the most significant shift in the report: surveyed organizations aren’t treating AI only as a risk to manage. They’re deploying it as a security asset. 82% of surveyed organizations now have plans to embed generative AI into their data security operations — up from 64% just one year ago.
From discovering sensitive data and detecting critical risks to investigating and triaging incidents, as well as refining policies, generative AI is being deployed for both proactive and reactive use cases at scale. The report explores how AI is changing the day-to-day operations across security teams, including the emergence of AI-assisted automation and agents.

Microsoft Security Copilot, embedded across Microsoft Sentinel, Microsoft Purview, Microsoft Entra and Microsoft Defender, puts this capability into practice — automating threat detection, helping to accelerate incident investigations and helping security teams stay ahead of an evolving threat landscape without sacrificing human oversight.
What comes next
As organizations confront the challenges of data security in the age of AI, the 2026 Data Security Index report offers three clear imperatives: unifying data security, increasing generative AI oversight and using AI solutions to improve data security effectiveness.
