Microsoft 365 Security Assessment: Identify Security Gaps, Prioritize Risks
You use Microsoft 365 every day — but do you know whether identities, access, endpoints, and security capabilities are actually configured appropriately? A Microsoft 365 Security Assessment makes security risks, misconfigurations, and unused protection options visible. You receive a clear evaluation of your current situation and prioritized recommendations for the next steps.
How secure is your Microsoft 365 environment really?
Many security risks are not caused by missing products, but by unclear settings, legacy permissions, or unused protection features.
An assessment provides a reliable overview: Where are the concrete risks? Which actions make sense first? And which improvements can be implemented with reasonable effort?
What is a Microsoft 365 Security Assessment?
The assessment is a structured technical review of selected Microsoft 365 security areas. Existing configurations are analyzed against the agreed assessment criteria, risks are classified, and concrete improvement opportunities are documented.
Which areas are reviewed in the assessment?
Each area can be commissioned individually or in a suitable combination. The exact scope is aligned during the initial consultation.
Entra ID
Identities, user and admin accounts, as well as roles and permissions.
MFA & Conditional Access
Multi-factor authentication and policy-based access controls.
Microsoft Defender
Configuration and use of existing Microsoft Defender capabilities.

FAQ on Microsoft Security Assessment
Am I automatically protected with Microsoft 365?
No. Microsoft 365 provides security features, but it is not automatically securely configured. The assessment reviews agreed areas and highlights misconfigurations, risks, and unused protection options.
Is Microsoft Secure Score alone enough?
No. Microsoft Secure Score is a useful orientation value. The assessment evaluates findings in the context of your environment, prioritizes risks, and derives concrete actions.
What exactly do I get for my investment?
You receive a structured review with documented findings, a prioritized risk assessment, and concrete actions. This includes a results report, risk matrix, and checklist so recommendations can be applied and your security posture improved.
Why is the assessment important before introducing Copilot or Agent 365?
The assessment helps secure your environment before using Microsoft 365 Copilot or Microsoft Agent 365. Depending on the agreed scope, we review areas such as agent identities, permissions, data access, and key governance and security policies so risks are visible before productive use.
Can individual areas be commissioned separately?
Yes. Each listed area can be commissioned individually or in a suitable combination. We align the exact scope in the initial consultation.
Are changes made during the assessment?
No. The assessment is an analysis. Changes to your environment are not part of the review.
Is additional software installed?
No. No additional software is installed in your environment for the assessment.
Will operations be interrupted?
No. The review is designed so that ongoing operations are not interrupted.
Is implementation of the recommendations included?
No. Implementation is not part of the assessment, but it can be commissioned separately.
Does the report fulfill a formal audit or cyber insurance requirements?
No. The report is a technical decision basis, but it does not replace a formal audit and does not automatically meet cyber insurance requirements.
Is there a fixed price?
No public fixed package price is provided. Effort depends on scope and current situation. The initial consultation is free and non-binding.
What happens to access rights after completion?
Access rights granted for the assessment are removed after completion.
