Office 365 hardening

Keep your business communications secure with stronger protection for emails, files, and collaboration tools.

Why office 365 hardening matters

Office 365 is central to modern business operations, serving as the hub for email, collaboration, and data storage. Even minor misconfigurations or overlooked vulnerabilities can expose your organization to phishing, unauthorized access, and data breaches.

Ensuring your Office 365 tenant is robustly secured is essential for protecting sensitive information and maintaining operational continuity.

By rigorously assessing and hardening your Office 365 environment, you can:

  • Enforce robust user authentication and access controls.

  • Secure critical services like Exchange Online, Teams, OneDrive, and SharePoint.

  • Achieve and maintain compliance with industry regulations.

  • Mitigate risks and protect your business communications from emerging threats.

Our 4-stage approach to Office 365 hardening

1st Stage

Office 365 Tenant Review

We start with a full security assessment of your Office 365 setup, identifying gaps and vulnerabilities in:

  • Email System (Exchange Online)

    Reviewing configurations and security policies.

  • MS Teams, OneDrive & SharePoint

    Ensuring secure permissions and access controls.

  • AzureAD & Global Permissions

    Strengthening identity management and authentication.

Once the review is complete, you’ll receive a detailed report outlining actionable steps to strengthen your Office 365 security and enhance your email reputation.

Office 365 Tenant Hardening

Next, we implement the best security practices to strengthen your defences:

  • Setting Up Tenant MFA with Microsoft Authenticator App

    Adding an extra layer of security. 

  • Protecting Organization’s Reputation with Domain Security

    Configuring SPF, DKIM, and DMARC. 

  • Reconfiguring Resource Access

    Ensuring only authorized users have access to sensitive information. 

  • Deploying Conditional Access and Tenant Backup

    Enforcing security policies and ensuring regular data backups. 

  • Deploying Spam and Malicious Email Protection

    Filtering out threats before they reach your inbox. 

3rd Stage

Office 365 Follow-Up Periodic Tenant Review

Every 60 to 90 days, we reassess your Office 365 environment to:

  • Validate security configurations.

  • Adjust settings to match evolving risks.

  • Ensure compliance with best practices.

4th Stage

  • Reports on Login Failures

    Detecting potential security breaches. 

  • Notifications on User Privilege Changes

    Tracking access level adjustments. 

  • Alerts on Suspected Unauthorized Activity

    Enabling prompt responses to potential threats.
