Emails, documents, spreadsheets, presentations and collaborative workspaces all live in the cloud, accessible from anywhere. That’s great. But it’s also risky. The uncomfortable truth is that Microsoft doesn't protect Microsoft 365 data the way many users think it does. ## The Microsoft 365 shared responsibility model: A wake-up call Many organizations operate under the dangerous misconception that Microsoft will protect their Microsoft 365 data against cyberattacks, accidental deletions or data loss incidents. Unfortunately, that's not how it works. Under the shared responsibility model outlined in the Microsoft 365 service agreement, Microsoft is responsible for the infrastructure and uptime of its services. But businesses themselves are responsible for protecting, backing up and restoring their own data in the event of a cyberattack, user error or other data loss scenario. This isn't just a technical detail. It's a critical business risk that could have serious consequences: * **Cyberattacks and ransomware**: When attackers compromise Microsoft 365 environment, Microsoft won't restore encrypted or deleted data. * **Accidental deletions**: When a user permanently deletes critical emails or documents, they may be unrecoverable. * **Legal and compliance requirements**: Businesses subject to e-discovery requests in lawsuits need to be able to produce data that may have been deleted. * **Regulatory compliance**: Industries governed by HIPAA, GDPR and other regulations face significant fines for failing to protect sensitive customer or patient data.

Cyberattacks on businesses, specifically ransomware, continue to grow in both frequency and sophistication. Now, cybercriminals have a powerful new tool in their arsenal: AI. Generative AI tools are enabling attackers to: * Create more convincing phishing emails that bypass traditional detection. * Scale up attack frequency and reach more targets. * Identify and exploit new vulnerabilities faster than ever before. Microsoft 365, filled with valuable business data, is a prime target. And without proper backup and protection measures in place, a successful attack could be devastating. ## How Acronis Cyber Protect safeguards Microsoft 365 data This is where Acronis Cyber Protect comes in.
