10 way to secure your Microsoft 365 tenant

Securing your Microsoft 365 tenant is crucial to protect your organization’s data and operations. Here are the top 10 things you should do:

Enable Multi-Factor Authentication (MFA)

This adds an extra layer of security by requiring users to verify their identity through a second method, such as a phone or app.

Train Your Employees

Educate your team about security best practices, phishing attacks, and how to handle sensitive information1.

Manage User Accounts and Permissions

Assign the least privileged roles necessary for users to perform their tasks. Avoid using global administrator accounts for daily operations.

Configure Microsoft Defender for Office 365

Use this tool to protect against threats like phishing, malware, and ransomware3.

Use Microsoft Purview Information Protection

Implement data loss prevention (DLP) policies to protect sensitive information from being shared inappropriately.

Disable Auto-Forwarding for Email

Prevent automatic email forwarding to external addresses to reduce the risk of data leaks1.

Protect All Devices

Ensure that all devices accessing Microsoft 365 are secure, using tools like Microsoft Intune for mobile device management.

Monitor and Audit Security Policies

Regularly review and update your security policies. Use auditing tools to track and respond to suspicious activities.

Configure Email Authentication

Set up SPF, DKIM, and DMARC records to prevent email spoofing and phishing attacks3.

Backup Data Regularly

Use third-party backup solutions to ensure you can recover data in case of accidental deletion or ransomware attacks.
