BVault — your corporate storage solution.

bvault is the corporate drive that runs on cheap object storage — with the Microsoft sign-in your company already uses, per-user audit, and immutable versions (WORM) that ransomware can't destroy.

The problem

Your Microsoft 365 storage filled up — and it's expensive to keep.

Companies that produce heavy files pile up more than SharePoint was built to store cheaply. The obvious exits cost you control, accountability, or security.

Add-on space is pricey

Extra SharePoint storage runs about R$ 1,100 per TB/month. A few TB turns into tens of thousands of reais a year.

A shared account with no owner

Moving to a shared Google Drive or Dropbox is cheaper, but nobody knows who did what — and revoking one person's access becomes a mess.

Ransomware reaches the cloud too

Synced means exposed: a hijacked file on the desktop becomes a hijacked file in the cloud. With no immutable version, there's nowhere to roll back.

How it works

From sign-in to a mounted drive in minutes.

The user's password never touches bvault — Microsoft authenticates, and the system only receives the already-validated identity.

1

Connect Microsoft 365

The company authorizes bvault in Entra ID. No user migration, no second password store.

2

Everyone signs in with Microsoft

SSO sign-in, no new password, with two-step verification. Permissions come from the M365 groups you already manage.

3

Files land in a dedicated bucket

Each company gets its own isolated bucket, with versioning and an immutability lock (Object Lock WORM).

4

The drive mounts as a network drive

Personal folder plus team folders on Windows and Linux. Sharing just points to a group folder. Everything audited.

Why bvault

What only bvault delivers together.

Cheap storage without giving up the governance your company already has.

Immutable by default (WORM)

Once written, a file can't be changed or deleted during retention — not even by someone with the password. That's what stops a ransomware attack.

Microsoft sign-in, no new password

SSO via Entra ID. Drive permissions are the Microsoft 365 groups you already administer — no second console to maintain.

Per-user audit

Every access is logged and tied to a person. You know who touched what and when — traceable for audits and incidents.

Multi-tenant isolation

Each company gets a dedicated bucket and database isolation (RLS). Your data never shares space with another client's.

High throughput

Uploads and downloads parallelized across many streams: speed is limited by your internet, not by our side.

Billed per TB, not per user

Unlike Dropbox, Box, or Google Workspace, the cost doesn't explode as the team grows — you pay for space, at object-storage prices.

Security & trust

Immutable by default. Isolated per company. Proven in production.

Not just another cloud drive. It's storage designed to resist ransomware and human error.

Object Lock / WORM in Compliance mode

Immutable versions that not even the administrator can remove. We chose Backblaze B2 precisely for offering this strong mode.

Dedicated bucket + per-tenant RLS

Physical isolation (bucket) and logical isolation (Row-Level Security). Each company sees only its own data.

History that cleans itself

Versions kept for a window (e.g. 30 days) with automatic expiry — protection without bloating the account like SharePoint.
