Big protection for small businesses — the latest in Microsoft security innovation
Published Mar 23 2023 08:45 AM 6,453 Views

In today's rapidly evolving digital landscape, cyberattacks are becoming increasingly sophisticated and prevalent. Small and medium-sized businesses are particularly vulnerable due to budget constraints and limited specialized security skills. In fact, 43% of all cyberattacks target small businesses, and the consequences can be serious within months of an attack.1


That's why it's more important than ever for small businesses to modernize their security solutions and move away from traditional antivirus software. Microsoft continues to develop a comprehensive set of security solutions that are easy to use, cost-effective, and specifically designed for small businesses including Microsoft 365 Business Premium, and Microsoft Defender for Business. In this blog post, we'll explore the latest updates to these solutions that will provide big protection to small businesses.

  • Preview monthly security summary reports.
  • Device exposure score in Microsoft 365 Lighthouse.

Our continued goal is to help keep your devices and servers secure so you can focus on what matters most - running your company.


Simplified security for iOS and Android without device management or add-ons – in preview.


We made it easier for you to protect their mobile devices from cyber threats such as malware and ransomware on both iOS and Android, without the need for device management or costly add-ons, with mobile threat defense in Defender for Business standalone.


Mobile threat defense offers three capabilities:

  1. Stay up-to-date and help prevent threats with operating system-level threat and vulnerability management.
  2. Block and help protect against phishing and unsafe website links that may come via email, text message, or apps with Web Protection.
  3. Detect malicious Android apps that could disrupt the device or steal data with App Security.

Protecting mobile devices is important as businesses increasingly rely on them for their operations. Now with Microsoft Defender for Business, data can be kept secure on desktops, laptops, and mobile devices, no matter where employees are.
