Hornetsecurity Launches '365 Total Backup' for Microsoft 365

News Overview Hornetsecurity, part of the Hornetsecurity Group that provides cloud-based cybersecurity solutions, has officially launched '365 Total Backup,' a new backup solution for Microsoft 365 (M365) environments.

Background: The Threat of Ransomware Ransomware attacks pose a significant business risk. According to Hornetsecurity's research, 24% of global companies suffered from ransomware in 2025, and nearly 1 in 2 (45.8%) of Japanese companies have experienced an infection. As backup data is increasingly targeted, the standard features of M365 are insufficient, creating a need for an independent, secure backup environment.

Key Features of 365 Total Backup - **Comprehensive Protection with a Single License**: Protects Exchange Online, SharePoint Online, OneDrive for Business, Teams, Planner, OneNote, and Entra ID without additional options. - **Unlimited Storage**: Storage without capacity limits eliminates the burden of budget planning. - **Easy Deployment and Automatic Backups**: API integration allows for same-day deployment. Multiple daily automatic backups and multi-tenant management significantly reduce operational man-hours. - **Multi-Layered Defense**: Uses immutable backups and a 'double-check approval process'—requiring two authorized users—to prevent tampering from insider threats or accidental deletion. - **Rapid, Granular Recovery**: Allows pinpoint restoration of necessary data. Self-service features significantly reduce the burden on IT administrators and waiting times. - **Audit Logs for Compliance**: Records all operations to support compliance audits and investigations.

With this launch, Hornetsecurity expands its business, which was previously centered on M365 email security, to provide a comprehensive security enhancement solution including data protection.
