Design and implement a Microsoft-aligned Zero Trust programme across identity, devices, data, apps, network, and infrastructure.
Zero Trust is a security strategy based on three principles: verify explicitly, use least privilege access, and assume breach. Microsoft’s guidance frames Zero Trust as an end‑to‑end approach spanning identities, endpoints (devices), data, applications, infrastructure, and networks - supported by visibility, automation, and orchestration.
LW IT Solutions delivers Zero Trust as an implementable architecture and hardening programme - not a slide deck. We baseline your current posture, define the target policy model, and deliver controlled hardening across the relevant Microsoft workloads (Entra ID, Intune, Defender, Purview, Azure). The outcome is a measurable uplift in security posture with documented decisions, change control, and an operating cadence that keeps controls effective over time.

Service Overview
Highlights
- Zero Trust assessment: baseline across identity, devices, data, apps, infrastructure, and network using Microsoft-aligned guidance
- Target architecture and policy model: define what good looks like for your organisation and risk profile
- Identity hardening: MFA strategy, Conditional Access patterns, privileged access model, and access governance alignment
- Device hardening: endpoint compliance policy model, secure configuration, device risk signals and access enforcement
- Data protection: sensitivity labels, DLP, retention/records, and risk-led governance for high-value data
- App and cloud controls: SaaS governance and access controls; cloud workload security and configuration hardening
- Network/infrastructure hardening: segmentation and blast-radius reduction; Azure hardening aligned to Zero Trust guidance
- Operationalisation: backlog, change control, runbooks, and a repeatable posture review cadence
Business Benefits
- Reduce breach impact by limiting blast radius and improving detection and response readiness
- Improve access decisions by verifying explicitly using identity, device, and risk signals
- Reduce standing privilege through least-privilege and privileged access patterns
- Create a defensible security programme with documented controls, decisions, and measurable posture uplift
Typical use cases
- Organisations moving from perimeter-based security to cloud-first policy-driven controls
- Post-incident hardening programmes or security uplift after major migrations
- Regulated environments requiring evidence-led security architecture and control governance
- M365/Azure tenants with inconsistent policies and unmanaged exceptions
- Security leadership needing a credible roadmap and measurable outcomes (not just high-level diagrams)
Objectives & deliverables
What Success Looks Like
- A Microsoft-aligned Zero Trust target architecture and policy model tailored to your organisation
- A prioritised hardening backlog with phased rollout plan and change impact understood
- Implemented controls for the agreed scope, with operational runbooks and governance cadence
What You Get
- Zero Trust baseline report (current posture, key gaps, risk hotspots, and quick wins)
- Target architecture and control model (identity, devices, data, apps, infrastructure, network)
- Prioritised remediation backlog (risk, effort, dependencies, and sequencing)
- Implemented hardening changes for agreed quick wins / pilot scope with validation evidence
- Governance pack: change control guidance, exception model, operational runbooks, and review cadence
How It Works
- Discovery and baseline - agree scope and gather posture evidence across the Zero Trust pillars.
- Target design - define the desired policy model and control architecture aligned to your risk profile.
- Backlog and sequencing - prioritise changes by risk reduction and business impact; plan pilots and rollouts.
- Implement and validate - deliver staged hardening with change control, testing, and measurable outcomes.
- Operationalise - handover runbooks, define governance cadence, and support ongoing improvements.
Engagement Options
- Zero Trust Assessment & Roadmap (baseline + target model + prioritised backlog)
- Zero Trust Quick Wins Sprint (high-impact improvements delivered with change control)
- Zero Trust Hardening Programme (phased rollout across identity, devices, data, and cloud controls)
- Operate (monthly/quarterly posture reviews, backlog management, and continuous improvement delivery)
Additional Information
Prerequisites & licensing
Zero Trust is an architectural approach rather than a single product. Implementing the recommended controls depends on which Microsoft services you use and the licensing available in your tenant (for example: Entra, Intune, Defender, Purview). During discovery we confirm scope and feature availability, then design the programme accordingly.
- We confirm the policy decision points (typically Microsoft Entra ID) and how device/risk signals will be evaluated.
- We define an exception and break-glass model to avoid locking out administrators or disrupting critical operations.
- We stage high-impact changes through pilots and phased enforcement to manage risk.
