Is Your Charity’s Microsoft 365 Really Secure? Here’s How to Find Out

Understanding Microsoft 365 Security Basics for Charities

For charities, Microsoft 365 is more than just a productivity suite—it’s the backbone of collaboration, communication, and data management. Yet, the sensitive nature of donor information, beneficiary records, and internal communications makes robust security absolutely crucial. Understanding the fundamentals of Microsoft 365 security is the first step toward safeguarding your charity’s digital environment.

At its core, Microsoft 365 offers a layered security approach designed to protect users from evolving cyber threats. Charity organisations should be familiar with the following:

• Identity and Access Management: Tools like multi-factor authentication ensure only authorised personnel can access sensitive data.
• Data Protection: Encryption and advanced threat protection shield emails, documents, and cloud files from prying eyes and malicious attacks.
• Compliance Controls: Built-in compliance features help charities adhere to data protection regulations and donor confidentiality requirements.

By understanding these basics, charities can begin to assess where their Microsoft 365 security stands and what steps are needed to strengthen it further.

Review Microsoft Secure Score

If you’re concerned about the security of your charity’s Microsoft 365 environment, a fundamental first step is to review your Microsoft Secure Score. This built-in tool provides a comprehensive, real-time assessment of your organization’s security posture by analyzing your current configurations, user behaviors, and security controls across Microsoft 365 services. The Secure Score delivers a percentage rating that reflects how well your charity is protected against potential threats—and, just as importantly, it identifies specific areas where your defences could be strengthened.

To get started, access the Microsoft 365 Security Center and navigate to the Secure Score dashboard. Here, you’ll see a detailed breakdown of your current score alongside prioritized recommendations for improvement. These actionable suggestions might include enabling multi-factor authentication, setting up advanced threat protection policies, or tightening sharing permissions on sensitive documents. By regularly monitoring and acting on your Secure Score, your charity can proactively address vulnerabilities and foster a culture of continuous security improvement.

Understanding your Secure Score empowers your organization to make informed decisions, ensuring Microsoft 365 remains a safe foundation for your mission-driven work.

Check MFA Adoption

Ensuring your charity’s Microsoft 365 environment is secure begins with evaluating Multi-Factor Authentication (MFA) adoption. MFA is a critical security measure that requires users to provide two or more verification factors before accessing their accounts. This additional layer of protection significantly reduces the risk of unauthorized access—even if passwords are compromised.

Start by reviewing your organization’s current MFA policy within the Microsoft 365 admin center. Are all user accounts, including privileged admin accounts, required to use MFA? Pay special attention to staff, volunteers, and any third-party collaborators with access to sensitive data. Statistics show that organizations without widespread MFA adoption are far more likely to experience security breaches.

Key Steps to Assess MFA Adoption

• Audit your user directory to identify accounts without MFA enabled.
• Review sign-in logs for risky sign-ins or repeated failed attempts.
• Ensure onboarding processes include mandatory MFA setup for new users.

By prioritizing MFA adoption, your charity takes a proactive step toward safeguarding donor data and maintaining trust. Next, let’s explore how to evaluate user permissions for additional security assurance.

Review Conditional Access

Conditional Access stands as a cornerstone in safeguarding your charity’s Microsoft 365 environment. By acting as a gatekeeper, it allows you to set precise policies that determine who can access your organization’s resources, from where, and under what circumstances. Begin by auditing your existing Conditional Access policies—are they comprehensive enough to address modern threats? For example, review whether policies enforce multi-factor authentication for all users, especially those with administrative privileges or access to sensitive data.

It’s also essential to consider scenarios such as remote work and device compliance. Are users restricted from signing in from unfamiliar locations or unmanaged devices? Regularly updating these policies ensures that only trusted users and secure devices can interact with critical information. Additionally, leverage reporting tools within Microsoft 365 to monitor sign-in attempts and policy effectiveness, identifying any gaps that could leave your charity vulnerable.

Thoroughly reviewing and refining your Conditional Access policies is a proactive step toward a more secure, resilient digital environment for your organization.

Review Defender

When it comes to protecting your charity’s Microsoft 365 environment, the first line of defense is Microsoft Defender. Many organizations overlook the importance of regularly reviewing their Defender settings, assuming that default configurations offer adequate security. However, cyber threats targeting charities have evolved, making it crucial to ensure your Defender solution is not only active but also optimally configured.

Begin by verifying that Microsoft Defender is enabled across all user accounts and devices. Check for real-time protection, automated investigations, and the latest threat intelligence updates. Dive into the security dashboard to review recent alerts and incidents—pay close attention to unresolved threats or repeated attack patterns. Adjust your alert policies so that you’re notified immediately when suspicious activity arises.

• Enable advanced threat protection features, such as anti-phishing and safe links.
• Run periodic security scans and review results for any anomalies.
• Ensure all software and Defender definitions are up to date.

By thoroughly reviewing your Defender setup, you lay a solid foundation for safeguarding sensitive donor data and maintaining your charity’s digital trust.

Check Backup

Ensuring that your charity’s Microsoft 365 data is properly backed up is a fundamental step in safeguarding against accidental loss, cyberattacks, or unexpected system failures. Many organisations mistakenly believe that Microsoft 365 automatically secures all data with comprehensive backups. In reality, while Microsoft does implement some redundancy and short-term retention policies, these measures are not substitutes for a dedicated backup solution.

Without reliable backups, emails, documents, and shared files can be irretrievably lost due to accidental deletion, malicious intent, or ransomware attacks. To assess your charity’s backup status, review whether you have a third-party backup service in place that covers Exchange Online, SharePoint, OneDrive, and Teams. Confirm that your solution performs regular, automated backups and allows for granular restores—enabling recovery of single files or entire mailboxes as needed.

By proactively checking and strengthening your backup strategy, you establish a vital safety net that protects your charity’s mission-critical information and ensures business continuity no matter what challenges arise.

Review DLP

Data Loss Prevention (DLP) is a cornerstone of any robust Microsoft 365 security strategy, especially for charities handling sensitive donor and beneficiary information. DLP policies act as a vigilant gatekeeper—monitoring, identifying, and preventing the accidental or intentional sharing of confidential data both inside and outside your organisation. Start by assessing whether your current DLP settings align with your charity’s unique data protection requirements. Are policies in place that specifically target the types of sensitive information you handle, such as financial records or personal identifiers? Examine how your rules are configured: do they trigger alerts when staff attempt to send confidential files externally, or when large volumes of data are being accessed? Regularly reviewing DLP reports can uncover patterns of risky behaviour and highlight areas where additional employee training may be needed. By making DLP a central focus, your charity can confidently safeguard its digital assets and maintain compliance with privacy regulations.
