Defender Consolidation Program

Consolidate security capabilities into the Microsoft Defender stack with a phased, low-risk programme - baseline, pilot, coexistence, cutover, and operational handover.

Security tooling sprawl increases cost and operational complexity: multiple consoles, duplicated alerting, inconsistent response, and unclear ownership. Microsoft Defender XDR provides a cross-domain threat protection and incident experience designed to help security teams identify, control, and remediate threats across attack surfaces. Microsoft also documents how Microsoft Sentinel and Defender XDR can be integrated to support incident response workflows in a Zero Trust approach.
LW IT Solutions delivers a Defender consolidation programme that is designed to reduce risk and avoid disruptive ‘big bang’ changes. We baseline your current tools and coverage, map your requirements to Microsoft Defender capabilities, and run a staged rollout with pilot-first onboarding and coexistence where needed. We finish with an operationally mature outcome: clear incident handling workflows, tuned alerts, governance controls, and a decommission plan for legacy tools - so consolidation produces real value, not just a licensing change.

Talk through your requirements and leave with a clear next-step plan.

Service Overview

Highlights

  • Phased programme approach to avoid disruptive big-bang migrations
  • Covers endpoint, identity, email, and cloud app security consolidation into Defender XDR
  • Focus on SOC-operable outcomes: incident workflows, tuning, and ownership
  • Supports Defender and Sentinel integration where required
  • Includes decommission planning so consolidation results in real simplification

Business Benefits

  • Reduced tool sprawl and operational overhead through a consolidated security platform approach
  • Improved incident handling with clearer ownership, routing, and investigation workflow consistency
  • Cost rationalisation through reduced duplication and clearer licensing-to-capability alignment
  • Higher-quality detections through tuning and an outcome-driven coverage roadmap

Typical use cases

  • Multiple overlapping endpoint and cloud security tools creating duplicated alerts
  • Organisations moving from third-party EDR to Microsoft Defender for Endpoint
  • Security teams needing consistent incident handling across domains
  • Rationalising licensing and capability alignment across Microsoft security stack
  • Preparing to integrate Defender incidents into an existing SOC workflow

Objectives & deliverables

What Success Looks Like

  • Consolidate security capabilities into Microsoft Defender with minimal disruption
  • Achieve validated coverage before decommissioning legacy tools
  • Improve incident response consistency through defined workflows and severity model
  • Reduce alert noise through tuning and governance controls
  • Establish an operating model that remains supportable as the environment evolves

What You Get

  • Consolidation assessment: current tooling inventory, coverage map, and operational pain points
  • Target architecture and operating model: what lives in Defender vs Sentinel, and how incidents are handled end-to-end
  • Phased rollout plan: pilot, phased onboarding, coexistence/cutover, decommission
  • Alert and incident workflow design: severity model, routing, escalation, and evidence handling
  • Governance pack: onboarding checklist, exception approvals, and change control to prevent drift
  • Decommission plan: exit approach for legacy tooling (when safe and agreed), including stakeholder and supplier considerations

How It Works

  1. Baseline - inventory existing security tools, data sources, workflows, and pain points; confirm success criteria.
  2. Design - map requirements to Defender capabilities and define a target operating model (including Sentinel integration where required).
  3. Pilot - onboard a controlled scope and validate alerting, incidents, and response workflows; tune to reduce noise.
  4. Scale - phased onboarding across workloads; implement governance and reporting cadence; manage coexistence.
  5. Cutover & decommission - execute controlled cutover and decommission legacy tooling when coverage and operations are proven.
  6. Operationalise - handover runbooks and backlog for continuous improvement.

Engagement Options

  • Assessment & Plan - current-state review and phased consolidation roadmap
  • Pilot First - implement a controlled Defender pilot with tuning and workflow validation
  • Phased Consolidation - staged onboarding across multiple workloads with coexistence and cutover
  • Operate - ongoing tuning, governance, and support for Defender-led operations
