A compromised identity can give an attacker the same access as a trusted employee, often without exploiting a single endpoint. That is why an Entra ID security assessment should not be treated as a configuration check completed once a year. It is a practical way to understand who can access your systems, how that access is protected, and whether you can prove controls are working.
For many organisations, Microsoft Entra ID sits at the centre of daily operations. It connects people to Microsoft 365, cloud applications, devices, external collaborators and increasingly sensitive business data. Small gaps in identity management can therefore have a large operational impact. The aim is not to make every setting as restrictive as possible. It is to reduce meaningful risk while keeping the business able to work.
What an Entra ID security assessment should answer
A useful assessment gives leaders and technical teams clear answers to three questions: where do we stand, what needs attention first, and how do we demonstrate improvement?
It should examine the security of identities, authentication, privileged access, applications and tenant-wide configuration. It should also look beyond the technical settings. A policy that requires multi-factor authentication is not enough if exceptions are undocumented, accounts are not reviewed, or nobody owns the action when a control fails.
The strongest assessments combine configuration findings with evidence of how identity processes operate in practice. This matters because a tenant can appear well configured on the day it is reviewed while still carrying unmanaged guest accounts, dormant administrators or risky legacy access paths.
An assessment is also context-dependent. A small business using Microsoft 365 for email and collaboration will have different priorities from an organisation with several cloud subscriptions, a large remote workforce and third-party applications using Entra ID for single sign-on. The principles remain consistent, but the remediation plan should reflect the services in use, the sensitivity of data and the likely impact of disruption.
Start with the identities that matter most
Not all accounts carry the same level of risk. Privileged accounts, emergency access accounts, service accounts and identities with access to finance, customer data or production systems deserve early attention. If one of these accounts is compromised, the consequences can be disproportionate.
Review how many privileged roles exist, who holds them and whether permanent access is genuinely required. Global Administrator roles should be tightly limited. Separate administrative accounts from standard day-to-day accounts where practical, so browsing the web or reading email does not take place with elevated privileges.
Emergency access accounts require particular care. They are necessary when normal authentication routes fail, but they can become an overlooked route into the tenant. They should be controlled, monitored and tested, with ownership clearly assigned. A break-glass account that nobody has validated for two years is not a reliable resilience measure.
The assessment should also identify inactive accounts and leavers. Delayed removal of access is a common and avoidable weakness, especially where HR, IT and line management processes are disconnected. Evidence should show not only that an offboarding policy exists, but that access is actually removed within the organisation’s defined timescale.
Test authentication against real-world risk
Passwords alone are not sufficient protection for cloud identity. Multi-factor authentication should be applied consistently, particularly for administrators and users accessing sensitive resources. Yet simply reporting an MFA adoption percentage can conceal risk. The important question is which users are excluded, why they are excluded and whether that decision is still appropriate.
An Entra ID security assessment should review Conditional Access policies in detail. These policies can require stronger authentication, restrict access by location or device state, and apply different protections to higher-risk activities. Poorly designed policies, however, can create lockouts or unexpected service disruption. Changes should be tested, documented and rolled out with a recovery plan.
Legacy authentication is another area that deserves attention. Older protocols may bypass modern authentication controls and are frequently targeted in password-spray attacks. If a legacy protocol remains necessary for a business application, document the dependency, minimise its use and set a date to review or replace it. An exception without an owner is simply an accepted risk that has been forgotten.
Phishing-resistant methods, such as passkeys or hardware security keys, can provide stronger protection for high-value users. They may not be the immediate priority for every organisation, but they are worth considering for administrators, executives and teams handling sensitive data. The right approach depends on risk, budget and users’ ability to adopt the method successfully.
Check access, applications and external collaboration
Entra ID often accumulates access over time. Employees change roles, projects end and applications are introduced by different departments. Without periodic review, users can retain permissions they no longer need.
Look at how access to groups, enterprise applications and administrative roles is granted and removed. Where possible, use clear approval routes and time-limited access for elevated tasks. The goal is not bureaucracy. It is to ensure that access decisions are traceable, proportionate and reversible.
Third-party applications need the same scrutiny. Review the permissions granted to applications, who can consent to them and whether unused applications remain connected. An application with broad mailbox, file or directory permissions can create material exposure even if the user account itself is well protected.
Guest access also needs a defined approach. External collaboration is often essential, particularly for suppliers, advisers and project teams. The question is whether guest accounts are invited deliberately, granted only the access required and reviewed when the relationship changes. Regular access reviews are especially useful where collaboration spaces contain commercial or personal information.
Turn findings into a prioritised improvement plan
A long list of technical observations rarely creates better security. It can leave a small IT team unsure where to begin. Every finding should be translated into an action that has an owner, a priority, a target date and a clear definition of completion.
Prioritise issues according to likely impact and ease of exploitation. For example, unprotected privileged accounts, weak emergency access arrangements and unmanaged legacy authentication usually warrant quicker action than low-impact configuration refinements. This does not mean lower-priority issues are ignored. It means the organisation makes informed decisions about sequencing.
A practical plan distinguishes between immediate fixes, planned improvements and accepted risks. Immediate fixes may include enforcing MFA for administrators or removing dormant privileged accounts. Planned improvements could include redesigning Conditional Access policies or implementing regular access reviews. Accepted risks should have a named decision-maker, a reason, compensating controls and a review date.
This structure helps security, compliance and leadership work from the same view of risk. Technical teams can see the configuration detail. Leaders can see why the action matters, what resources are needed and whether progress is being made.
Prove the controls are operating
Screenshots and spreadsheets can support an assessment, but they quickly become outdated and difficult to trust. Evidence should be current, attributable and connected to the control it supports.
For Entra ID, useful evidence may include policy settings, role assignments, authentication registration status, sign-in logs, access review results, application consent records and documented exception approvals. The exact evidence depends on the requirement being met and the control objective. More evidence is not automatically better. Evidence should be sufficient to demonstrate that the control is implemented and operating as intended.
Automated evidence collection can reduce manual effort and improve consistency, particularly for settings that change regularly. It should not remove human judgement. Someone still needs to interpret whether a finding is relevant, whether an exception is justified and whether the chosen action reduces risk. AI can help explain technical findings and recommend priorities. People decide what is appropriate for their organisation.
Cyber Fundamentals AI brings assessments, evidence, remediation ownership and reporting into one workspace, helping teams connect Entra ID findings to wider Cyber Essentials, CyFun, NIS2 and ISO 27001-related requirements without repeatedly recreating the same work.
Make identity security a continuous discipline
A point-in-time assessment is valuable, but identities and access change every week. New starters join, leavers depart, applications request permissions, suppliers gain access and Microsoft introduces new capabilities. A secure position can drift without anybody making a deliberately unsafe decision.
Set a review rhythm that matches your environment. Privileged roles and high-risk sign-ins may need frequent monitoring. Broader access reviews may be quarterly or triggered by role changes. Major changes to Conditional Access, applications or business processes should prompt a focused reassessment rather than waiting for the next audit cycle.
The most useful measure of progress is not the number of completed tasks. It is the reduction of known exposure, supported by evidence that controls remain in place. When an organisation can show what it found, what it fixed, who accepted remaining risk and how it monitors change, it is in a stronger position with customers, insurers, auditors and its own board.
Identity security becomes manageable when it is treated as a visible cycle of understanding, improvement and proof. Start with the accounts and access paths that could cause the greatest harm, assign ownership for the next action, and keep the evidence current enough to support confident decisions.
