Cloud Security Assessment for Microsoft 365 is a professional service offered by Onevinn that provides systematic security evaluations of Microsoft 365 environments. The assessment focuses on three primary areas: identity protection, device security, and data/information protection across the tenant. The service evaluates multiple Microsoft 365 workloads including Entra ID (Azure Active Directory), Exchange Online Protection, SharePoint Online, Microsoft Endpoint Manager (MEM/Intune), and OneDrive for Business. The assessment also covers Defender for Identity, Defender for Endpoint, and Defender for Office 365 configurations. Onevinn delivers a detailed technical report that analyzes the current security state of each workload, identifies vulnerabilities and security weaknesses, and provides recommendations to achieve best practice configurations. Each configuration item in the report includes a description, risk assessment, default state, current state, and specific recommendations. The assessment includes an executive summary meeting and a closing workshop focused on training and education to help organizations take control of their security and compliance settings. The service aims to help customers build a roadmap toward a secure baseline for Microsoft 365 workloads and protect against modern threats and cyber attacks. The methodology is based on 10 years of experience helping customers with security in both on-premises and cloud environments.
