Continuous protection
Every new version of every file in a protected site or drive is copied to immutable storage within minutes of the change — no schedules, no gaps, no windows an attacker can exploit.
Features
Everything you need to protect, tier and restore Microsoft 365.
One platform for immutable protection, storage savings and governance — with nothing to install and nothing standing between your users and their files.
Archival & tiering with stubs
Policy rules move cold data out of SharePoint and replace it with a clickable stub that keeps the name, metadata and permissions. Users never notice; your storage bill drops.
One-click restore
Restore a file, a version, or a whole site at a point in time — verified against its hash — from inside Teams, SharePoint or the web portal, with no IT ticket.
Retention & legal hold
Map retention schedules to Object-Lock dates (extend-only, never shorten). Place a legal hold that suspends archival and blocks expiry for the items in scope.
Sovereignty & region choice
Pick the storage region per tenant. UAE data can be kept entirely within the UAE, meeting residency requirements without extra work.
Zero-infrastructure onboarding
One admin consent to a multi-tenant Microsoft 365 app. No servers, no agents, no endpoints touched. You are protecting new changes the same afternoon.
Unified admin console
One place for site selection, policies, dashboards, restore jobs, quotas and per-tenant reporting — and, for partners, a multi-tenant operations view.
Complete audit trail
Every protect, archive, restore and admin action is recorded in an append-only, tamper-evident log — the evidence you need for PDPL, ISO 27001 and SOC 2 reviews.
