Identity & Workforce Security

Microsoft 365 Security Services

Microsoft 365 security depends on more than individual settings. Digisecuritas reviews identity, email, endpoints, applications, and data controls, then provides a clear plan to reduce risk.

Improve sensitive data controls

Microsoft 365 includes powerful controls

Their value depends on how they are configured.

Security settings often change as users, devices, applications, and licences evolve. An independent review shows where controls are working and where gaps remain.

Conditional Access gaps
Policies do not consistently cover every identity, device, or access scenario.
Privileged role exposure
Administrative permissions may be broader or more permanent than required.
Email policy inconsistency
Protection settings can vary across users, domains, and collaboration tools.
Unmanaged applications
Third-party and OAuth applications may retain unnecessary access.
Incomplete device coverage
Endpoint policies may not apply consistently across corporate and personal devices.
Sensitive data exposure
Information may be shared or retained without suitable controls.

One tenant. Multiple security layers. One independent view.

Example finding

Example security finding

Finding
Administrative accounts are excluded from key Conditional Access policies
High Priority
Observation
Some privileged accounts are excluded from key Conditional Access policies.
Why it matters
A compromised account could access sensitive systems with fewer controls.
Recommended action
Apply stronger authentication, device conditions, and emergency access governance.
