The risk you're ignoring

Microsoft guarantees uptime. Not your data.

Under Microsoft's Shared Responsibility Model, platform availability is their job. Protecting your data, your identities, and your compliance? That's entirely on you.

🗑️

Accidental Deletion

A user deletes a critical SharePoint site or Teams channel. Microsoft's recycle bin expires after 93 days. After that, it's gone — permanently.

🔐

Identity Compromise

An attacker modifies Conditional Access policies or deletes admin accounts in Entra ID. Without backup, rebuilding from scratch takes days and creates security gaps.

🦠

Ransomware

Encrypted files sync to OneDrive and SharePoint. Native versioning can't roll back entire tenants. You need immutable, air-gapped copies to recover cleanly.

👤

Insider Threats

A departing employee bulk-deletes emails and files. By the time you notice, Microsoft's retention window may have closed. No backup means no evidence trail.

⚖️

Compliance Failures

GDPR, DORA, and NIS2 require demonstrable data protection and recovery capabilities. Retention policies are not backup — regulators know the difference.

⚙️

Misconfigurations

A change to Entra ID policies locks out thousands of users. Without identity backup, restoring the exact previous state is manual, slow, and error-prone.

Shared Responsibility Model

What Microsoft protects — and what they don't

Most organisations assume Microsoft backs up their data. They don't. Here's who's actually responsible for what.
