Entra ID Risk in Focus: Why Backups Are Now Essential
Why the vulnerability is so dangerous
The newly disclosed Entra ID security flaw shows that an attacker can obtain global administrator rights with a single compromised token or unpatched legacy authentication mechanisms – almost invisibly.
The danger lies not only in the attack itself, but especially in its consequences:
Identities are a “single point of failure”
If Entra ID is manipulated, the company loses control over:
-
User accounts
-
MFA settings
-
App permissions
-
Security groups
-
Conditional Access policies
-
Administrator roles
Without this control, practically the entire Microsoft 365 environment comes to a standstill.
Attackers can cover their tracks
Certain attack paths leave almost no logs. Some token types cannot technically be revoked, meaning an attacker may remain in the system even after passwords and MFA have been reset.
A compromised Entra ID cannot simply be reinstalled
There is no switch like “Reset entire Active Directory”. When identity data is destroyed, manipulated, or deleted, the company is in an extremely difficult position – often without a recovery plan.
Why an Entra ID backup is essential
Microsoft does not offer full recovery of all Entra ID objects.
Deleted or manipulated objects such as:
-
Users
-
Groups
-
Roles
-
Service Principals
-
App registrations
-
Conditional Access policies
… can only be restored partially – or not at all, especially not to a defined point in time.
A targeted attack could therefore:
-
Delete administrator roles
-
Alter authentication methods
-
Manipulate group permissions
-
Sabotage critical app access
Without a backup, a company may be completely unable to operate.
How MOUNT10 helps: Full, independent, Swiss identity backup
A backup with MOUNT10 provides several key advantages that close exactly this gap:
Independent, isolated copies of Entra ID data
The data does not reside in Microsoft’s infrastructure but is fully separated – in Switzerland, inside the highly secure SWISS FORT KNOX.
Even if an attacker gains control over Entra ID, they cannot delete the backup.
Recovery of critical identity objects
MOUNT10 enables complete restoration of compromised Entra ID objects – a decisive advantage when vital identity data has been manipulated or deleted.
Protection against “silent attacks”
Because some Entra ID attacks are barely visible, companies often detect them too late.
With a backup, you can return to a previous, secure state – even when logs are incomplete.
Maximum geographic and legal security
All backups are stored in:
-
isolated, physically protected data centers
-
in Switzerland
-
outside the Microsoft cloud
-
fully under Swiss data protection law
For identity data, this separation is a major security advantage.
Identities are the new gold – protect them
The Entra ID vulnerability CVE-2025-55241 has clearly shown: even the strongest cloud infrastructure can suddenly become vulnerable. Identities are the foundation of modern IT – and an attack can paralyze an entire company.
An independent backup is not a “nice-to-have”, but a mandatory safeguard.
With MOUNT10, companies receive:
-
a sovereign, fully independent backup solution
-
highest Swiss data security
-
protection against attacks, misconfigurations, and human error
-
the ability to respond quickly and effectively in an emergency
If identities are the new attack surface No. 1, then an Entra ID backup is the most important line of defense.
