Google Drive

Google Drive, as part of Google Workspace for business/enterprise, offers advanced security features beyond its consumer version. These include data loss prevention (DLP), secure external sharing controls, VPC Service Controls to isolate data, and client-side encryption for select file types. Admins can control data region compliance and use Security Center for investigation. Deeply integrated with Google's AI and collaboration tools, it's a powerhouse for businesses already in the Google ecosystem.

Its score reflects its massive market presence, continuous innovation, and robust security tools available at the enterprise tier.
