Ransomware and identity recovery for Microsoft 365 and Entra ID

Recovery is the point of a backup. VaultFuzion keeps Microsoft 365 and Entra ID backups immutable and point-in-time, so after ransomware, an accidental mass-delete or a bad configuration change, you can restore to a known-good point. Backups are held under compliance-mode object lock that no one — not an attacker, not an administrator, not the vendor — can delete before retention expires.

Immutable by design

VaultFuzion writes backups under compliance-mode object lock (WORM), enforced by S3 Object Lock on the storage bucket — on bring-your-own-storage, a bucket you enable for Object Lock; on a VaultFuzion-provided bucket, on by default. Once a copy is written, it cannot be altered or deleted by anyone until its retention period ends. This is the property that matters after a serious ransomware engagement, where the threat model has to include a privileged account that has already been compromised. Append-only storage is not enough on its own — the question to ask any backup is whether a sufficiently privileged user could still remove the data, and under compliance mode the answer is no.

Point-in-time restore

Side-by-side

Recovered data lands beside what is live. Nothing existing is touched — the safe first move during an incident.

In-place

The backup merges into the live location, for a targeted bring-back of what was lost.

Exact-state

A location is reverted to precisely how it looked at a chosen point in time — the version of the tenant you want after a compromise.

Identity recovery is more than restoring users

An identity attack rarely deletes users — it adds persistence: a conditional-access policy quietly narrowed, a new administrator, an app registration granted broad consent. So recovering identity means recovering the configuration, not just the account list. VentraID backs up the Entra ID configuration graph and detects drift against a known-good baseline, so you can see what changed and restore the configuration to a point in time. The honest question to put to any identity-backup tool: if an attacker adds a Global Administrator today, how would you find it, and how would you roll the configuration back?

A tamper-evident record

Every backup, restore and retention action is written to a hash-chained audit trail. Modify any entry and every entry after it fails verification — so the record of what happened during an incident, and what you did to recover, is itself defensible.

Frequently asked questions

What makes a backup recoverable after ransomware?

Immutability. VaultFuzion holds backups under compliance-mode object lock (WORM): once written they cannot be altered or deleted by anyone — including a compromised administrator — until retention expires. A backup a privileged attacker can delete is not a recovery plan.

What is the difference between append-only and deletion-proof?

Append-only stops you overwriting history; it does not necessarily stop a sufficiently privileged account from removing the data outright. Compliance-mode object lock is deletion-proof for the retention period — that distinction is the whole game once your threat model includes a compromised admin.

Can VaultFuzion restore Entra ID, not just the users?

Yes. VentraID backs up Entra ID configuration — conditional access, groups, app registrations, service principals and more — and offers drift detection and point-in-time restore of that configuration, because an identity attack manipulates the policy graph, not just the user list.

How far back can I recover?

To any point you captured. Point-in-time restore is bounded by your backup frequency, and immutable retention means the historical points are still there when you need them.

Is the recovery itself auditable?

Every backup, restore and retention action is written to a hash-chained, tamper-evident audit trail, so you can prove what was recovered, when and by whom.
