Microsoft 365 Security Audit FAQs

What is a Microsoft 365 Security Audit?

A Microsoft 365 Security Audit reviews your tenancy to ensure it is configured securely and adheres to security best practices.

This includes examining user accounts, roles and permissions, email security, collaboration settings, and integration with other cloud services.

The assessment is typically aligned with known benchmarks, such as CIS.

Why is a Microsoft 365 Security Audit important?

Microsoft 365 stores sensitive corporate data and provides access to critical business applications. Misconfigurations or weak security controls can lead to data loss, regulatory breaches, or account compromise.

Our Microsoft 365 Security Audit helps prevent these risks and strengthens your company’s overall security posture.

Who benefits from a Microsoft 365 Security Audit?

Any company using Microsoft 365 can benefit. Start-ups, SMEs, and large enterprises all rely on Microsoft 365 for communication, collaboration, and storage.

Microsoft 365 Security Auditing ensures your tenancy is secure and compliant, regardless of company size.

When should a Microsoft 365 Security Audit be performed?

Microsoft 365 Security Audits should be conducted regularly, especially after major platform changes, user onboarding, or service configuration updates.

Performing an audit proactively prevents issues before they affect operations or compliance.

How is a Microsoft 365 Security Audit conducted?

Our team uses a combination of automated tools and manual review to assess your environment.

We examine account and permission settings, email protection, collaboration platforms, and integration with Azure services, among other things.

All findings are validated by an expert to remove false positives and ensure actionable recommendations.

What areas of Microsoft 365 can be security audited?

We can security audit Exchange Online, Teams, SharePoint, OneDrive, Microsoft Graph integrations, Azure Active Directory (Entra ID), and other Microsoft 365 services relevant to your tenancy.

What support do I get during a Microsoft 365 Security Audit?

You will have direct and dedicated access to our consultants throughout the engagement.

We provide daily progress calls, immediate alerts for any findings above an agreed CVSS severity level, and ongoing communication to minimise disruption to your business operations.

Our team conducts all work with professionalism and discretion, and we are available to answer any questions you may have during (and after) the test.

What do I receive after a Microsoft 365 Security Audit?

You will receive a comprehensive, prioritised report detailing all identified vulnerabilities, misconfigurations, and security risks. Each finding is accompanied by practical remediation guidance to help your technical teams implement fixes effectively.

The report is concise and bloat-free, focusing on the essentials to provide clear, actionable insight for both technical staff and management. To aid understanding, where practical, we supplement the report with video demonstrations of exploits, showing your team exactly how vulnerabilities were identified and exploited.

If required, a debrief session is included to review the results and discuss next steps.

Is a Microsoft 365 Security Audit cost-effective?

Yes.

Identifying and remediating security gaps in Microsoft 365 before they are exploited reduces the risk of costly incidents, data loss, and compliance penalties. Proactive auditing saves time, money, and effort compared to addressing breaches after they occur.

Regular penetration testing also helps avoid costly incidents, supports compliance, and demonstrates due diligence to clients and regulators.
