 | VMware ESXi                | Device     | High                      | The VMware ESXi hypervisor is essential for running and managing virtual machines within your infrastructure. As a bare-metal hypervisor, it's providing the foundation for creating and managing virtual resources. |
 | VMware vCenter             | Device     | High                      | The VMware vCenter Server is crucial for managing virtual environments. It provides centralized management of virtual machines and ESXi hosts. If it fails, it could disrupt the administration and control of your virtual infrastructure, including provisioning, migration, load balancing of virtual machines, and datacenter automation. However, as there are often redundant vCenter Servers and High Availability configurations, the immediate halt of all operations might not occur. Its failure could still cause significant inconvenience and potential performance issues. |
 | Hyper-V Server             | Device     | High                      | The Hyper-V hypervisor is essential for running and managing virtual machines within your infrastructure, serving as the core platform for their creation and management. If the Hyper-V host fails, it can lead to the unavailability of hosted virtual machines, potentially causing downtime and disrupting business operations. Moreover, it can result in significant performance degradation and operational challenges. Ensuring the reliability and stability of Hyper-V hosts is therefore critical for maintaining seamless operations in a virtual environment. |
+| SharePoint Server          | Device     | Medium                    | The SharePoint server is responsible for secure content management, collaboration, and document sharing across teams. It hosts intranet portals and enterprise search within an organization. Compromise could lead to unauthorized access to sensitive information and disruption of content services. |
