Microsoft 365, Azure and Cybersecurity Case Studies
Enterprise migrations, tenant consolidation, Azure architecture, Zero Trust, Microsoft Defender, Sentinel, Intune, Purview, SharePoint, Teams and Modern Workplace transformation.
This selection presents representative Microsoft engagements delivered by MSAdvance. Public references identify the client where publication has been authorized; other engagements are anonymized to preserve confidentiality commitments and sensitive organizational information.
Projects are defined by context, risk and objectives
Microsoft projects require a clear understanding of the current environment, technical dependencies, business requirements and operational constraints. That assessment determines the most appropriate architecture, technology and execution sequence.
Depending on the scenario, the scope may combine migration, identity, security, Microsoft Intune, Defender, Sentinel, Purview, Azure, collaboration or governance. Technology is selected according to the project objective, not the other way around.
The references on this page represent different engagement types and scales, from migrations and tenant consolidation to cybersecurity, Azure and Modern Workplace initiatives.

Confidentiality and anonymized references
Certain engagements are subject to confidentiality agreements that limit the information that can be made public. Where authorization exists, we identify the client and the scope that may be published. In other cases, references are limited to sector, scale, technologies and the nature of the work, without including information that could identify the client or expose sensitive details.
This approach allows MSAdvance to document relevant experience while maintaining the confidentiality commitments agreed with each organization.

How can we determine whether MSAdvance has delivered a similar project?
Share the approximate number of users, current platforms, Azure environment, devices, Microsoft 365 workloads, security requirements and the objective you need to address. We can then identify comparable scenarios and determine the information required to define the scope.
Share the context of your project and we will review the appropriate approach.
Tell us about the current environment, the requirement you need to address, the approximate scope and target date. Our team will review the information to identify dependencies, risks and the next steps required to define a technical scope.
