Nine governance domains

Microsoft 365 is not a single application. It is an ecosystem of interconnected services, integrations, and external connections. Inquilion assesses governance posture across nine domains covering this entire surface: from identity and access controls through to data residency, from email security through to the application and sharing configurations that determine what third-party tools can access organisational data and how information flows beyond the tenant boundary. Each domain is translated from technical configuration into governance language that any director can read, challenge and act on.

01

Identity and Access

Who can access what, how authentication is configured, and whether the controls preventing unauthorised access are operating as expected.

02

Data Protection

How organisational data is classified, shared and protected. Whether controls exist to prevent data leaving the organisation undetected.

03

Device Governance

Whether devices accessing organisational data are managed, compliant and operating within the board's risk appetite.

04

Email Security

How email is protected against impersonation, interception and misuse. Whether the controls in place match the risk the board carries.

05

Audit and Logging

Whether the organisation can evidence what happened, when, and by whom. The foundation for accountability and regulatory response.

06

Information Governance

Whether retention policies, records management, and lifecycle controls are in place to meet regulatory obligations. Whether organisational data is retained as required and disposed of when it should be.

07

Insider Risk Management

Whether policies are configured to detect and respond to insider risk signals, communication compliance obligations, and adaptive protection. Whether the organisation can evidence it has controls around internal threats.

08

Application and Data Sharing

Which external applications have access to organisational data, what permissions they hold, and whether that access has been formally approved. How external sharing, guest access, and Power Platform integrations are governed.

09

Data Residency and Sovereignty

Where organisational data physically resides, whether data location aligns with regulatory requirements, and how cross-border data flows are governed.

Every domain is assessed against governance expectations, not feature tiers or licence levels.

The governance domains and assessment scope shown here reflect the current Inquilion methodology as of March 2026. Domains, assessment checks, and regulatory framework coverage are subject to ongoing development as the regulatory landscape and the Microsoft 365 platform evolve.

What Inquilion does not do

The boundaries of the service are as important as the service itself. Independence depends on what we choose not to do.

We do not remediate

Findings are framed as actions for management. The board oversees remediation through its existing governance structures. If we fixed what we found, we could no longer independently assure it.

We do not advise on configuration

We assess configuration against governance expectations. We do not recommend how to configure anything. Advisory and assurance cannot coexist without compromising independence.

We do not replace audit

Inquilion complements formal audit by providing the independent evidence layer that auditors can reference but rarely produce themselves at the configuration level.

We do not manage your environment

We have no operational role in your Microsoft 365 tenant. No administrative access, no ongoing presence, no commercial dependency on your IT decisions.

Where Inquilion sits in your governance

Inquilion does not replace any function. It fills the space between operational reporting and formal audit, providing the independent evidence layer that boards need but rarely receive.

Board
Accountable for oversight. Receives independent assurance evidence. Challenges management on findings.
Inquilion
Independent assurance. Assesses configuration against governance expectations. Reports to the board. No delivery role.
Management
Responsible for delivery. Runs Microsoft 365 through IT team or managed service provider. Responds to board findings.

Oversight cannot be delegated to those responsible for delivery.

Independent evidence where previously there was assumption

If your board has not yet received independent evidence on how Microsoft 365 is configured, a conversation is the right first step.
