Why Microsoft 365 native protection is not enough

Microsoft guarantees infrastructure uptime—protecting data integrity, compliance, and ransomware recovery remains 100% your responsibility.

Microsoft's Responsibility

Microsoft operates cloud infrastructure, physical data center redundancy, and service uptime SLAs. Native recycle bins automatically purge deleted data after 30 to 93 days, leaving permanent data loss risks.

Your Responsibility

Protecting business-critical emails, OneDrive files, SharePoint lists, and Teams chats against accidental deletion, malicious insiders, ransomware synchronization attacks, and long-term regulatory compliance gaps.

Core resilience capabilities

Engineered specifically for IT administrators and MSPs requiring total data control, immutable security, and instant recovery.

Air-Gapped Immutable Storage (S3 WORM)

Back up directly to your own AWS S3, MinIO, Cloudflare R2, or local block storage. With S3 Object Lock in Compliance mode, backup snapshots are physically immutable and immune to ransomware modification or admin credential compromise.

Instant Granular Recovery

Locate and restore specific emails, OneDrive files, or SharePoint list items in seconds without bulk downtime or operational disruption.

Continuous Incremental Sync

Automated delta engine captures item changes continuously with zero impact on user productivity or Graph API rate limits.

MSP Multi-Tenant Management

Centralized control plane managing multiple customer tenants with complete data isolation, custom retention enforcement, and immutable audit logs.

Frequently asked questions

Key clarifications regarding M365 backup, immutability, and compliance.

Under Microsoft's Shared Responsibility Model, Microsoft guarantees physical data center uptime and infrastructure availability. Data protection, backup retention, ransomware recovery, and protection from accidental or malicious deletion remain 100% your responsibility. Native recycle bins purge items after 30 to 93 days.
When storing backups in S3 Object Lock Compliance mode (WORM), snapshot objects cannot be overwritten, modified, or deleted by any API call or compromised admin credential during the retention period.
You retain 100% data sovereignty. North Brook Vault connects to your own S3-compatible object storage (AWS S3, MinIO, Cloudflare R2, SeaweedFS) or local block storage.
