Context over alert noise

Data-centric protection

Security follows information

Audit-ready by design

Evidence built-in

// What this means

Security is a platform discipline - not a collection of products

Security failures are rarely caused by missing tools. They are caused by fragmented controls, unclear ownership and poor integration.

At Xetech, we treat security as a platform discipline, not a collection of products. The Microsoft Security Stack provides a tightly integrated ecosystem for identity protection, endpoint security, cloud workload defence, data governance and threat detection - when architected correctly.

Important note

This page describes how we design and structure the Microsoft Security Stack as an enterprise platform - not security services or operational processes.

Integration and control design
Measurable and auditable controls
Security aligned to business speed
// Design principles

Security platform design principles

Identity is the control plane

Access decisions are enforced before incidents occur.

Security follows data

Protection follows information and access - not devices alone.

Integrated telemetry

Context and correlation over isolated alerts.

Measurable & auditable controls

Controls must withstand scrutiny and produce evidence.

Operate at business speed

Security enables outcomes - it does not slow the organisation down.

These principles ensure security platforms reduce real risk - not just generate noise.

What we standardise (per platform layer)

01. Identity & Access Control Plane

Identity decisions are enforced before access is granted - not after incidents occur.
Entra ID as the central identity authority
Conditional access and authentication controls
Privileged access separation and elevation
Identity lifecycle and entitlement governance
Continuous access evaluation

02. Endpoint & User Protection Layer

Protection is applied consistently - regardless of location.
Device posture and health enforcement
Endpoint threat detection and response
Controlled access to corporate resources
Integration with identity-based controls
Visibility across managed and unmanaged devices

03. Cloud & Workload Protection

Cloud security is treated as architecture - not configuration.
Cloud workload protection posture
Secure configuration baselines
Threat detection across cloud services
Exposure and misconfiguration visibility
Integration with identity and network controls

04. Data Protection & Information Governance

Data protection operates independently of application logic.
Data classification and sensitivity models
Encryption and access enforcement
Information protection and labelling
Retention and lifecycle governance
Controlled data-sharing patterns

05. Security Monitoring & Threat Detection (SIEM)

Detection without context creates fatigue. The objective is actionable insight, not volume.
Centralised security telemetry
Risk-based detection use cases
Correlation across identity, endpoint and cloud signals
Incident prioritisation and triage models
Integration with response workflows

Integration across the stack

The Microsoft Security Stack is designed to function as one integrated platform. We architect environments where signals and controls reinforce each other.
Identity drives access decisions
Endpoint signals influence access risk
Cloud posture feeds detection logic
Data sensitivity controls exposure
Telemetry flows into a unified detection layer

Governance & auditability

Security platforms must withstand scrutiny. Auditability is designed into the platform - not manually assembled.
Policy-driven control enforcement
Continuous compliance visibility
Evidence generation for audits
Exception and risk acceptance tracking
Executive-level reporting

// Regulated environments

Security platforms in regulated environments

Security failures carry severe consequences

In healthcare, public sector and regulated industries, security platforms must operate within regulatory frameworks - not around them.

Regulatory compliance and reporting
Data privacy and protection obligations
Incident readiness and escalation
Multi-entity and multi-region oversight
Clear accountability and ownership
// Ecosystem integration

How security fits the platform ecosystem

Cloud platforms (Azure)

Workload protection, posture and cloud signals.

Azure Cloud
DevOps & Engineering platforms

Secure delivery pipelines and controls.

DevOps
Data platforms

Governed analytics and AI with protection.

Data & AI
Microsoft 365 & collaboration

Identity, data protection and compliance.

Modern Workplace
Security is embedded across the entire technology estate - not isolated in one toolset.

Strengthen your security

Architect an integrated Microsoft security platform that protects identity and data, improves detection, and stays audit-ready.
