Capabilities

Explore Microsoft Sentinel innovative capabilities

Industry-leading SIEM

Redefine your security operations center (SOC) with a modern, cloud-native SIEM that unifies AI, SOAR, UEBA, and TI.

Cost-effective data lake

Unify and centralize security data with scalable, cost-efficient storage to enable advanced analytics, AI, and cyberthreat detection without compromising performance or budget.

Graph-powered context

Centralize visibility and context across use cases that go beyond the SOC with a security graph built right into the platform architecture.

Intelligent Model Context Protocol (MCP) server

Translate natural language into executive tasks with the intelligence and reasoning layer of the platform that enables agents to discover, invoke, and interact with each other.

Native XDR integration

Empower security leaders with native extended detection and response (XDR) integration, delivering unified visibility and control across SIEM and XDR to accelerate cyberthreat detection, streamline investigation, and drive operational efficiency at scale.

Enterprise-wide visibility

Gain comprehensive visibility across multicloud and multiplatform environments through more than 350 native connectors and no-code custom integrations.

“Going with Microsoft Sentinel was a no-brainer to adopt a more holistic approach … rather than continue with that patchwork from different vendors.”
CIO, Retail

Cyberthreat protection

High alert volume and labor-intensive investigations
 

  • Limited detection engineering

  • Lack of automation

  • False positive and alert fatigue

  • Slow mean time to detect (MTTD)/mean time to resolution (MTTR)

  • Low visibility

  • Protracted incidents

  • Lengthy investigations

“Splunk is slower to adopt in terms of adding in features, event queries, event correlation, and understanding how to make sense of all of that data.”
Security Leader, Healthcare

AI-powered, high-fidelity threat detection and investigation

Find cyberthreats in the environment with enhanced AI-powered detection, correlation, and investigation capabilities—significantly reducing false positives and MTTR.

  • Development tools for custom detections

  • Proactive threat hunting with rules enhanced by machine learning (ML)

  • Integrated Security Copilot for AI assistance

  • Robust threat intelligence and alert enrichment

“By ingesting logs and alerts from our security solutions into Microsoft Sentinel, we can correlate threat analysis from multiple sources. This automation saves valuable time to resolve incidents.” 
Security Director, Telecommunications and media

Return on investment (ROI)/total cost of ownership (TCO)

Expensive, hard-to-scale platform operations
 

  • Unpredictable consumption costs

  • Additional modules required

  • On-premises infrastructure or cloud-hosted, but not cloud-native

  • Labor intensive operations

“Splunk ingestion costs are always top of mind because they get very expensive very quickly.”
CISO, Manufacturing

Flexible, cloud-native architecture with lower TCO

Get predictable, cost-efficient security to help reduce TCO.
 

  • Cloud-native scalability

  • Maximum flexibility

  • Efficient data management

  • Simplified operations with tailored, in-product recommendations

Time to value

Complex implementation with slow time to value
 

  • Insufficient migration support

  • Limited interoperability with ecosystem

  • Time-consuming custom integration and deployment

  • Lack of pre-built templates, rules, and playbooks

“If you don't have all [Palo Alto] tools, it’s difficult to get other platforms integrated.”
Director of IT Operations, Manufacturing

Rapid onboarding with pre-built solutions

Protect across clouds, platforms, and tools by using robust migration tools, an extensive content catalog, configuration recommendations, and pre-built, curated cyberthreat detection rules.

Security innovation

Insufficient roadmap vision and execution
 

  • Constrained research and development

  • Inadequate AI expertise and functionality

  • Underdeveloped features

  • Limited TI and security research professionals

“One of the challenges with Splunk is the lack of vision on their roadmap since the acquisition.” 
Security Leader, Banking
