Modern SecOps with Defender XDR and Sentinel

EPAM’s Modern SecOps with Defender XDR and Sentinel implementation enables CISOs, security leaders, and SOC teams to modernize and scale their security operations using Microsoft Defender XDR and Microsoft Sentinel SIEM. This offer is designed for organizations struggling with fragmented security tools, alert fatigue, slow incident response, and limited visibility across hybrid and multi-cloud environments. By adopting a Modern SecOps approach, enterprises can unify detection, investigation, and response while improving security posture and operational efficiency.

What You Will Receive

• Unified SecOps Platform: Design and implementation of a Microsoft-native SOC leveraging Microsoft Defender XDR and Microsoft Sentinel SIEM to centralize security operations.
• SOC Platform Engineering: Optimization or greenfield design of SOC operating model, processes, and tooling aligned with Microsoft’s Unified SecOps architecture.
• SIEM & XDR Migration: End-to-end migration from legacy SIEM/SOC platforms, including log onboarding, detection rule redesign, and cost optimization.
• Managed Detection & Response (MDR): 24/7 monitoring and incident response capabilities with reduced alert noise and faster triage.
• Threat Protection Optimization: Continuous tuning of detections, automation (SOAR), and SOC workflows to improve detection quality and response speed.

Typical Implementation Approach

Phase 1 — Assess & Advise

• Evaluate current SOC maturity, tooling, and security gaps.
• Define target Modern SecOps architecture and roadmap.
• Deliver assessment report, prioritized recommendations, and business case.

Phase 2 — Design & Build

• Design Microsoft Defender XDR and Microsoft Sentinel SIEM architecture.
• Configure data connectors, analytics rules, playbooks, and automation workflows.
• Implement identity, endpoint, and cloud security integrations.

Phase 3 — Migrate & Implement

• Migrate logs, detections, and use cases from legacy SIEM/XDR platforms.
• Deploy Infrastructure-as-Code (IaC), detection-as-code, and CI/CD pipelines.
• Validate detections, perform threat simulations, and execute cutover.

Phase 4 — Operate & Optimize

• Enable 24/7 SOC operations with MDR services.
• Continuously tune detection rules and automation playbooks.
• Provide knowledge transfer, runbooks, and operational dashboards.

Expected Outcomes

• Streamlined SOC operations with reduced complexity and improved analyst productivity.
• Faster, AI-augmented incident detection and response across all environments.
• Enhanced security posture through unified visibility and threat protection.
• Continuous security optimization with automated workflows and cost-efficient operations.
• Production-ready SecOps platform with documented architectures, playbooks, and governance model.
