Where Microsoft stops - your real protection begins

How to secure your 365 environment with Acronis Ultimate 365

Microsoft is powerful – but not impenetrable. Microsoft 365 is the backbone of most organizations’ digital workflows and everything lives there. Well, that’s exactly why cybercriminals see Microsoft environments as real gold mines.

However, many companies believe that Microsoft “takes care of everything,” but the truth is different. Microsoft is responsible for running the platform, while you, the customer, are responsible for securing your own data.

This means that everything from misconfigured sharing settings to ransomware attacks, deleted files, or leaked user credentials can quickly become your problem - not Microsoft’s.

Even though Microsoft 365 offers powerful tools, the ecosystem is complex. That’s why we’ve listed a few of the most common weaknesses we see in corporate Microsoft environments.

The most common security gaps in Microsoft 365 1. Misconfigured access controls

It’s easy for an external consultant, former employee, or partner to still have access to data. Incorrect sharing settings or groups without MFA (Multi-Factor Authentication) make the environment vulnerable.

2. Email as the entry point

Phishing remains the most common attack vector. Fake Microsoft login pages, emails “from the boss,” or malicious links in Teams messages fool users every day.

3. Lack of real backup

Many organizations rely on Microsoft’s built-in version history or recycle bin - but that’s not a true backup. Data can be permanently deleted after 30–90 days or encrypted by ransomware. When disaster strikes, you need an independent and secure backup solution.

4. The human factor

Technology can’t protect against stress, mistakes, or lack of awareness. A wrongly shared folder or a single careless click can open the door to an attacker.

How Acronis Ultimate 365 fills the gaps

To achieve truly comprehensive protection, you need a combination of backup, monitoring, training, and active defense, without making it expensive or overly complex.That’s where Acronis Ultimate 365 comes in.

2. Email protection and anti-phishing

   Detects and blocks malicious links, attachments, and phishing attempts before they reach the user.
