Owner at Nexus Auto system
Digital documentation has boosted team efficiency and provides secure remote manual access
The best feature is the mobile access to SharePoint. It is incredibly valuable for our technicians to view wiring diagrams and manuals directly on their tablets while working under a vehicle. It removes the need to walk back to the office, saving about 20 minutes per job. Additionally, the data security features give me peace of mind; even if a tablet is broken in the shop, our business data remains safe in the cloud.

System Engineer at a retailer with 10,001+ employees
Collaboration has transformed how our teams work and Copilot now drives faster daily decisions
The interface for the security and compliance center could be simplified. It changes frequently, which can make it somewhat difficult for admins to stay up-to-date on where specific settings are located. The compliance center modification or improvement of Office 365 needs to be introduced. The rest of the features feel acceptable to me. The reason it is not a ten is because of the complexity of managing the vast array of admin settings, which requires a specialized IT team. Even though it meets industry standards for decent security compliance such as SOC and HIPAA, the complexity of managing the admin settings needs to improve.
