Secure Your Microsoft 365 Environment

Microsoft 365 is the backbone of modern business operations. Our security review ensures your tenant is configured to defend against evolving cyber threats.

Many organisations rely on default Microsoft 365 configurations, leaving critical security gaps that attackers actively exploit. From business email compromise to data exfiltration, misconfigured M365 tenants are a prime target.

Our Microsoft 365 Security Review provides a thorough examination of your tenant configuration across all key services. We identify weaknesses, benchmark against Microsoft best practices and industry standards, and deliver actionable recommendations to harden your environment.

Whether you're preparing for a compliance audit, responding to a security incident, or simply want to understand your current security posture, our review delivers the insights you need.

Aligned with Microsoft Secure Score Our assessments reference Microsoft's own security benchmarks and CIS recommendations.

Why Default Settings Aren't Enough

Microsoft 365 is secure by design, but not by default. Attackers frequently exploit legacy authentication and MFA bypass techniques to launch ransomware and financial fraud campaigns.

Our audit identifies these "silent" risks, ensuring your Microsoft Secure Score reflects real-world resilience, not just a checklist.

What We Review

A comprehensive assessment covering all critical Microsoft 365 services and configurations

Entra ID (Azure AD) & Identity

Identity is the new security perimeter. We assess user authentication, Conditional Access Policies, MFA configuration, privileged identity management, and guest access controls.

Protect your documents and collaboration spaces. We assess sharing policies, external access controls, site permissions, Data Loss Prevention (DLP) settings, and Sensitivity Labels.
