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

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

“The idea of a cloud-native SIEM like Microsoft Sentinel was attractive ... it offers us flexibility and the cost-effective product we need for our solution portfolio.” Information Security Engineer, Financial services

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

FAQ

Frequently asked questions

  • Microsoft Sentinel is a cloud-native SIEM that helps security teams detect, investigate, and respond to cyberthreats across multi-cloud, multiplatform environments — with built-in AI, automation, and a cost-effective data lake for long-term log retention. It unifies with Microsoft Defender for one-incident workflows.
  • Yes — Microsoft Sentinel is a cloud-native SIEM. It runs on Microsoft's broader security platform (Microsoft Security IQ), which powers AI-driven workflows across products like Security Copilot. For platform / data fabric details, see the Microsoft Security IQ page.
  • Microsoft Defender is a suite of tools that unifies prevention, detection, and response across endpoints, identities, email, and applications to deliver a consolidated view of threats, adaptive protection against cyberattacks, and streamlined incident response and remediation.

    Microsoft Sentinel delivers extended visibility and foundational SecOps tools with built-in SIEM, SOAR, UEBA, and TI to detect, investigate, and respond to cyberthreats efficiently across the entire digital estate.

    Both Microsoft Defender and Microsoft Sentinel are fully integrated in the Microsoft Defender portal, delivering unparalleled native detection and automated response with extended visibility, flexibility, and scalability.
  • No, Microsoft Sentinel is designed to ingest and analyze security data from a wide variety of sources across multicloud, multiplatform environments. Microsoft Sentinel integrates with more than 450 different solutions through connectors supported by Microsoft and third-party partners.
  • Microsoft Sentinel uses a built-in data lake for affordable long-term log retention, includes SOAR, UEBA, threat intelligence, and case management, and runs cloud-native, thereby eliminating infrastructure overhead. AI-driven SOC optimization further reduces ingestion costs and analyst time on triage.
  • Microsoft Sentinel SIEM migration experience uses AI to convert detection rules from Splunk, QRadar, and other legacy SIEMs into native Sentinel detections, reducing manual effort and shortening migration timelines from quarters to weeks. Pre-built migration playbooks and codeless connectors accelerate onboarding. The first step is analysis-only: it reviews your legacy SIEM exports to identify what maps cleanly vs. needs review, and which data sources/connectors are required for coverage. It does not automatically enable connectors and detections or retire your existing SIEM. Execution starts only when you choose to proceed and align on migration scope and ownership.
