Despite a high awareness of cybersecurity risks, the company’s Microsoft 365 environment had a comparatively low Secure Score of just 46%. The main reason for this was a heterogeneous tenant configuration, which had arisen due to rapid company growth and several M&A activities. As a result, there was a lack of a consistent security architecture, which favored potential vulnerabilities in identity and device management.
In addition, the company was increasingly confronted with KRITIS requirements from new major customers – combined with the expectation of operating a demonstrably hardened Microsoft 365 tenant. The goal was clear: a significantly higher security standard, measured among other things by a secure score of at least 80%, combined with a sustainable and auditable solution.
In order to raise the IT company’s Microsoft 365 tenant to a secure and audit-proof level, we carried out a comprehensive security assessment including a GAP analysis. The aim was to uncover critical vulnerabilities, develop a structured action plan and carry out a step-by-step hardening of the tenant. The focus was on the Secure Score as an objective measure – combined with the actual security situation in day-to-day operations.
