Penetration Testing of Microsoft Cloud Applications

Vulnerability detection

Many organizations are unaware that they use and own cloud services on a daily basis. These services, often overlooked by IT administrators, can become targets of attacks and entry points for cybercriminals. Cloud services are not limited to on-demand servers, data centers, or serverless applications. They also include commonly used and well-known solutions such as Microsoft Teams, Outlook, or SharePoint.

Penetration tests of cloud environments are controlled attempts to breach security measures and simulate the misuse of services beyond their intended purpose. Their goal is to detect weaknesses and assess threats before they become actual attack targets. All actions are conducted in a fully controlled manner to ensure data protection.

Key objectives of penetration tests

1

Verification of protection level

Check how effectively your systems defend against real threats.

2

Configuration identification

Detect areas that may require improvement before being exploited by attackers.

3

Adaptation of defense mechanisms

Minimize the risk of data leakage, service availability loss, or unauthorized modification of information.

4

Ensuring business continuity

Ensure your organization can operate without disruption even in case of an attack.

Why conduct cloud penetration testing (Microsoft 365 / Azure)?

Penetration testing of cloud environments helps identify configuration errors, excessive permissions, and security vulnerabilities. With the growing number of attacks and regulatory requirements such as NIS2 or DORA, regular testing is crucial for both security and compliance.

With penetration testing, you can

Verify cloud protection

Check if your M365 and Azure environment is properly secured against attacks.

Detect configuration errors

Identify settings that expose your organization to risk.

Evaluate the effectiveness of MFA and access policies

Test whether login and access control mechanisms work as intended.

Secure accounts and permissions

Ensure users have only necessary privileges and accounts are not susceptible to takeover.

Meet regulatory requirements

Tests support compliance with standards such as NIS2, DORA, or GDPR.

Types of penetration tests for cloud environments

We offer four types of penetration tests tailored to various cloud threat scenarios. These tests help detect vulnerabilities, assess service configurations, and identify areas for security improvement in Microsoft 365 and Azure.

1

Black-box tests

Simulation of an attack from an external threat perspective, with no information about your cloud environment. They assess the security of publicly available resources – such as web applications in Azure, storage services, or user accounts.

2

Grey-box tests

Environment verification with partial access – for example, a user account or configuration documentation. Ideal for evaluating access policies, permissions in Azure AD, or authentication effectiveness in M365.

3

White-box tests

Full security analysis with access to tenant configurations, security policies, protection systems, procedures, and hosted services. Allows for an in-depth assessment of cloud resource protection and identification of issues not visible externally.

4

“Slow” (long-term) tests

Simulation of slow, targeted attacks on the cloud environment. These tests evaluate the effectiveness of monitoring (e.g. Microsoft Sentinel), alerting, and SOC team responses to privilege escalation attempts or account abuse.

Support and re-testing of cloud environments

Our cooperation does not end with the report delivery. We actively support your team in improving the security of environments such as Microsoft 365 and Azure. Our goal is not only to identify risks but to help effectively eliminate them and secure the cloud in line with best practices.

What we offer as part of support?

Consultations Discussion of the report and recommendations.

Re-tests Verification whether vulnerabilities have been removed.

Ongoing support Assistance until the environment is fully secured.

Execution process

Each project is executed according to clearly defined stages, ensuring transparency and control over the progress:

1.

Needs analysis and goal definition

We begin with a detailed discussion of your requirements and expectations. We define test objectives and jointly determine the project’s goals.

2.

Refining project details

We define the test scope, environments, and completion criteria. This ensures that activities are fully aligned with your business needs.

3.

Project kick-off

We start the cooperation with a kickoff meeting, during which we discuss the action plan, schedule, and team roles in detail.

4.

Scope and environment verification

We verify the readiness of the test environment and the defined scope to ensure everything aligns with the assumptions.

5.

Task execution

We conduct penetration tests transparently, providing the client with visibility into progress at each stage.

6.

Report with findings

We deliver a report including detected vulnerabilities, remediation recommendations, risk assessment (CVSS), and references to OWASP Cloud-Native Top 10, comprehensible for all stakeholders.

7.

Consultations

We review the report so your team can fully understand and effectively implement the recommendations to eliminate identified vulnerabilities.

8.

Re-tests

After implementing fixes, we recommend re-testing to verify the effectiveness of changes and ensure full system security.

9.

Feedback after re-tests

We provide conclusions from the re-tests, indicating which vulnerabilities were effectively eliminated and which require further attention.

Why trust us?

Every project we undertake is equally important to us. We always strive to deliver solutions that not only enhance security but also provide a deep understanding of processes. Our references, certifications, and experience confirm that quality, responsibility, and understanding our clients' needs are the foundations of every collaboration with us.
