MICROSOFT ECOSYSTEM SECURITY
Protect the Connections Across Your Microsoft Estate
Microsoft environments connect identity, endpoints, collaboration, cloud workloads, applications and data. A weakness in one area can create a trusted route into another.
Digisecuritas helps organisations understand those connections, test whether Microsoft security controls work as intended and prioritise the changes that reduce meaningful exposure.
Independent assessment across Microsoft 365, Azure and hybrid environments.

THE MICROSOFT ECOSYSTEM PROTECTION GRID
Security weakens when connected controls are managed in isolation
Microsoft's Zero Trust guidance groups security into connected technology pillars — identity, endpoints, applications, data, infrastructure, networks and security operations. Use that model to examine cross-platform dependencies while keeping recommendations specific to the organisation.
Band 1: Identity and privilege
Prevent identity compromise from becoming broad administrative control.
Capability areas
- Microsoft Entra
- Conditional Access
- Identity Protection
- Privileged Identity Management
Questions to resolve
- Is strong authentication applied consistently?
- Which roles remain permanently privileged?
- Are emergency access paths controlled?
- Who owns external and workload identities?
Evidence to review
- Role assignments
- Authentication methods
- Access policies
- Risk and audit events
Band 2: Devices
Use device state to make better access decisions.
Capability areas
- Microsoft Intune
- Defender for Endpoint
- Device compliance
- Endpoint security policies
Questions to resolve
- Which devices are known and managed?
- Does device risk affect access?
- Are security policies applied consistently?
- What can personal devices reach?
Evidence to review
- Enrolment coverage
- Device compliance
- Endpoint health
- Access exceptions
Band 3: Email and collaboration
Reduce exposure through communication, sharing and external collaboration.
Capability areas
- Exchange Online
- Microsoft Teams
- SharePoint
- OneDrive
- Defender for Office 365
Questions to resolve
- How is malicious email handled?
- Which external-sharing paths exist?
- Are guest users still required?
- Can sensitive downloads be controlled?
Evidence to review
- Email-protection policy
- Sharing configuration
- Guest access
- Audit records
Band 4: Azure and applications
Protect workloads, subscriptions and application identities.
Capability areas
- Azure role-based access
- Defender for Cloud
- Azure Policy
- Workload identities
- Key Vault
Questions to resolve
- Who can administer subscriptions and workloads?
- Which services are externally exposed?
- Are secrets and certificates governed?
- Is security logging consistently enabled?
Evidence to review
- Role assignments
- Resource configuration
- Cloud-security findings
- Diagnostic settings
Band 5: Data protection
Align access and protection with the sensitivity of information.
Capability areas
- Microsoft Purview
- Sensitivity labels
- Data loss prevention
- Information lifecycle controls
Questions to resolve
- Where is sensitive information?
- Are labels applied consistently?
- Which users can share or export it?
- Do retention controls match business requirements?
Evidence to review
- Classification coverage
- DLP policies
- Sharing events
- Retention configuration
Band 6: Detection and response
Connect signals across the ecosystem and make incidents actionable.
Capability areas
- Microsoft Defender XDR
- Microsoft Sentinel
- Security alerts
- Automation and playbooks
Questions to resolve
- Which signals contribute to incidents?
- Are alerts relevant and owned?
- Can compromised accounts or devices be contained?
- Are response procedures tested?
Evidence to review
- Incident configuration
- Data connectors
- Detection rules
- Investigation records

HOW WE WORK
Review the connections before optimising the products
01
Establish the Microsoft footprint
Confirm tenants, subscriptions, products, identities, devices, applications, data and connected third-party tools in scope.
02
Map control dependencies
Identify how identity, device, application, cloud and data controls contribute to access, prevention and response.
03
Validate the evidence
Review configuration, policy, telemetry and operating procedures. Test selected controls where authorised.
04
Prioritise improvement
Separate urgent exposure, configuration work, process changes and longer-term architecture decisions.
Recommendations should distinguish controls already available, genuine licence dependencies and unnecessary capability overlap.
Where Microsoft protection commonly loses consistency
Conditional Access exclusions
Policies appear strong while legacy access, emergency accounts or broad exclusions weaken coverage.
Excessive administrative roles
Powerful permissions remain permanently assigned across tenants and subscriptions.
Unmanaged application identities
Service principals, applications, secrets and certificates operate without clear ownership.
Fragmented device coverage
Some endpoints report risk and compliance while others reach the same resources without equivalent checks.
Sensitive sharing paths
Guest access, collaboration and downloads move information beyond the intended control boundary.
Alerts without operating ownership
Microsoft security tools generate incidents without a consistent triage, escalation or containment process.
What your organisation receives

Independent Microsoft security advice without a licensing agenda
Ecosystem before product silos
The assessment examines how Microsoft controls influence one another.
Configuration supported by evidence
Enabled features are not treated as effective without coverage and operating evidence.
Licensing considered carefully
Recommendations separate unused capability, configuration gaps and genuine licence dependencies.
Microsoft and non-Microsoft context
Connected third-party tools and hybrid systems remain part of the risk view.
