Ransomware-proof
Every file version is copied to storage that physically cannot be deleted or changed until retention expires — not by an attacker, a rogue admin, or even us.
Microsoft 365 data protection · UAE-sovereign
The safety net and cost-control layer beneath your Microsoft 365.
Immutable ransomware protection, policy-driven archival that cuts storage cost, and one-click restore for SharePoint and OneDrive — with zero infrastructure to deploy.
- Built for Microsoft 365
- CloudOnBox sovereign storage
- UAE data residency
Why CloudOnBox
Six reasons it belongs under every Microsoft 365 tenant.
Cut storage cost
Cold data — typically 60–80% of a tenant — moves to storage about 25–30× cheaper than SharePoint overage, with no egress fees to restore.
Sovereign
The protected copy stays in the storage region you choose. UAE data stays in the UAE, under your control and residency rules.
Zero infrastructure
One admin consent. No servers, no software on PCs, no new licences. Your Microsoft logins, MFA and Conditional Access govern everything.
One-click restore
Bring a file — or a whole site at a point in time — back in a couple of clicks, from inside Teams, SharePoint or the web portal. No IT ticket.
Audit-ready
Retention, legal hold and a complete, tamper-evident audit trail — built toward UAE PDPL, ISO 27001 and SOC 2 requirements.
How it works
Live in an afternoon. Protecting from the first change.
01
Connect
Grant one consent to the CloudOnBox Microsoft 365 app and pick the sites and accounts to protect. Least-privilege — access only what you choose.
02
Protect & archive
Every change streams through, is encrypted, and lands in immutable storage within minutes. Policies tier cold files out of SharePoint, leaving a clickable stub.
03
Restore
Anyone with rights restores a file or a point-in-time copy in two clicks — verified against its hash — right where they already work.
Storage economics
Most of your SharePoint bill is cold data.
Move the 60–80% nobody edits to sovereign storage that costs a fraction of Microsoft's overage rate — and keep it one click from restore. See your number in seconds.

Security & compliance
Immutable by design. Sovereign by default.
Object-Lock immutability, per-tenant envelope encryption, hard tenant isolation, and least-privilege Microsoft Graph access. We never hold your passwords and never store your file bytes — they only stream through, in memory.
