Cybersecurity Simplified: Protecting Your Business from Ransomware with Microsoft 365 Business Premium

Created by Rohit Yadav, Modified on Tue, 9 Sep at 10:52 PM by Rohit Yadav

Ransomware is one of the fastest-growing threats to small and medium-sized businesses. It’s a form of malicious software that blocks access to your files or entire computer until a ransom is paid.

Instead of protecting your data with encryption, ransomware uses encryption against you—locking your documents, images, and videos until you pay up. Even worse, an infected device can spread ransomware across your entire company network.

Example of a Ransomware Attack

An employee receives an email from a “friend” with a link to a video showing how to use chopsticks to make heart-shaped boiled eggs. Curious, they click the link and select Run. Suddenly, their screen changes, and a message appears saying all their files have been hijacked and encrypted. The only way to regain access? Pay the ransom.

Three Ways Microsoft 365 Business Premium Protects You from Ransomware

1. Email & Link Protection with Microsoft Defender for Office 365

  • Scans emails and attachments for malicious content.

  • Uses “sandboxing” to analyze suspicious files before delivery.

  • Safe Links feature checks every link when clicked, blocking malicious sites.

2. Device Protection with Microsoft Defender for Business

  • Goes beyond traditional antivirus with Threat & Vulnerability Management.

  • Provides Endpoint Detection and Response (EDR) to stop targeted attacks.

  • Automatically investigates suspicious behaviors and blocks ransomware attempts.

  • Protects common folders (Documents, Pictures, Desktop) from unauthorized encryption.

3. File Recovery with OneDrive for Business

  • All files stored in OneDrive are automatically versioned.

  • In case of an attack, you can roll back to a clean version that predates ransomware infection.
