Microsoft Defender Threat Intelligence Convergence: What It Means for Security Operations

Microsoft is in the middle of one of its most important evolutions in the Defender ecosystem: the convergence of Microsoft Defender Threat Intelligence (MDTI) into the Microsoft Defender Portal, Sentinel, and Defender XDR.

This change marks a structural shift in how threat intelligence will be consumed across SOCs and MDR services over the next few years.

Defender Threat Intelligence: From Premium Add-On to Standard Capability

Until now, MDTI Premium was a standalone product. Access to advanced threat intelligence—finished reports, raw telemetry, actor profiles, IOC feeds, and CVE insights—required a separate license.

With the convergence, that barrier disappears:

• All Defender XDR and Sentinel customers gain access to previously “premium-only” intelligence
• No additional licenses or standalone portal are required
• Access is controlled through Defender role-based access (RBAC)

This democratization of threat intelligence means that a much wider base of organizations will operate with access to the same premium intelligence Microsoft analysts use internally.

How MDTI Convergence Transforms Security Operations Centers

Enhanced Proactive Vulnerability Management with Defender XDR

High-quality CVE intelligence tied directly to an organization’s environment allows for sharper vulnerability management. Rather than drowning in generic feeds, SOC teams can prioritize based on real exposure in their install base, shifting the focus from reacting to alerts toward mitigating vulnerabilities before exploitation.

Automated Incident Enrichment and Threat Context in Sentinel

With convergence, Defender XDR entity pages and Sentinel incidents are automatically enriched. Analysts no longer need to pivot into a separate tool to understand:

• Whether an IP or domain is linked to threat actor infrastructure
• Which TTPs, CVEs, or campaigns are related
• What reputation scoring reveals about the entity

This reduces investigation time and improves response quality by embedding enrichment directly where analysts work.

Streamlined SOC Workflows and Multi-Tenant Operations

Multi-tenant SOCs and MDR providers will benefit from standardized enrichment, IOC feeds, and finished reports available across all customers. With fewer silos, intelligence becomes a force multiplier, enabling analysts to focus on remediation rather than manual intelligence gathering.

When combined with Security Copilot, enriched data drives stronger AI-assisted workflows, making complex environments easier to manage.

Microsoft Defender Threat Intelligence Convergence Timeline

Microsoft is targeting August 2026 for full completion, with three phases:

Phase 1 (In progress):

• Intel Profiles integrated into Threat Analytics
• Defender entity pages enriched with MDTI intelligence
• Sentinel Data Lake introduced for unified storage

Phase 2:

• Intel Explorer folded into the Defender Portal search bar
• Intel Projects converged with Defender Cases
• More enrichment added to entity pages
• Threat Analytics becomes available to Sentinel-only users

Phase 3:

• Advanced Threat Intelligence enabled by default across alerts, incidents, and hunting
• APIs released under the Defender umbrella
• Sentinel’s entity pages replaced by enriched Defender entity pages

At the end of this roadmap, MDTI as a standalone product will retire. Its features will live fully within the Defender ecosystem.

Strategic Impact on Enterprise Security Operations

The convergence is more than a product simplification: it redefines the baseline for enterprise threat intelligence.

• Standardized access eliminates uneven intelligence capabilities across organizations
• Lower cost-to-serve by removing separate licensing requirements
• Accelerated onboarding for new customers in multi-tenant SOC scenarios
• Better automation and AI outcomes thanks to richer intelligence feeding Copilot and playbooks

Optimizing Security Operations with Unified Threat Intelligence

The unification of MDTI into Defender XDR and Sentinel signals a fundamental shift in security operations. By 2026, what was once a premium capability will become the default intelligence fabric inside the Defender ecosystem.

For enterprises and MDR providers alike, this unlocks faster incident response, proactive vulnerability management, and more scalable SOC operations—without additional licensing complexity.
