M365 Security Testing – The Right Approach for Your Company
Individual pentest and analysis approaches for Microsoft 365
Whether during the initial rollout or in ongoing operations: security in Microsoft 365 is crucial for trust, compliance, and business continuity. With our pentest and analysis approaches, you not only receive technical findings but also clear recommendations for action that reduce your risks and secure your M365 environment in the long term.
The typical problem
Companies are increasingly relying on Microsoft 365 – and with the widespread use, the demands on security and governance are also increasing. However, many audits focus only on technical vulnerabilities. Configurations, permissions, and processes remain unconsidered – but this is precisely where the greatest risks often arise.
Finding the right testing depth
Not every security analysis is the same. While some customers benefit from a quick black box test, others need a deeper analysis of configuration and governance. We offer four clearly defined approaches that are oriented towards your goals – and ensure that you receive exactly the results that move you forward.
M365 in transition
Constant function updates complicate a consistent security level, as they frequently introduce new functions and changes that can influence existing security configurations. This dynamic requires a continuous adjustment of the security guidelines, in order to minimize potential vulnerabilities and to guarantee the protection of the environment.
Our Services
- Blackbox Pentest: Blackbox pentests simulate the perspective of an external attacker who acts without prior knowledge of the target system. These tests make it possible to identify security gaps by systematically demonstrating technical vulnerabilities. The testers use a wide variety of methods to explore and document potential attack vectors. The focus here is not on the standard Microsoft functionality, but on weaknesses that arise from your own configuration and adjustments.
- Configuration Analysis: Configuration analyses provide a comprehensive review of all M365 settings and security configurations. Potential vulnerabilities and misconfigurations are identified to ensure the security of the environment. The analysis is carried out using both automated tools and manual checks.
- Governance-First: Our governance-first approach begins with the analysis of business processes, protection requirements, and relevant policies. This approach ensures that security measures are tailored to the specific requirements of the company. This is followed by a technical review to evaluate the implementation of the defined policies.
- Hybrid Approach (our recommendation): The hybrid approach combines the perspectives of attack and configuration analyses with governance principles. This integration enables a comprehensive assessment of the security situation and policy implementation. This maximizes the benefits of the various approaches to effectively strengthen IT security.

The limits of a regular pentest: A classic pentest simulates attacks on your M365 system. This is valuable – but often only part of the big picture. Misconfigurations, unclear permissions, and missing security policies usually arise long before an attack.
Especially with new or gradually introduced environments, a pure black box pentest offers little added value. What is needed is an approach that combines technology and governance – and preferably before sensitive data, external collaboration, or complex services go live.
