Why it matters
Where the exposure usually sits.
Microsoft 365 is powerful, but its defaults favour easy adoption over tight security. In most tenants the real exposure falls into four areas, and very little of it is visible from the inside.
Identity is where attackers sign in
Most intrusions start with a valid login rather than a broken lock. Legacy authentication and uneven MFA leave accounts easier to take over, and every extra global admin widens the damage one compromise can do.
Data leaves more quietly than you expect
Open SharePoint and OneDrive links share more widely than intended. Add over-permissioned third-party apps and weak email authentication, and information can move outside the business with no one signing off.
Defaults favour adoption, not security
Conditional Access, device compliance, and tenant baselines ship loose so Microsoft 365 is easy to roll out. Left untouched, they let unmanaged devices and risky sign-ins reach company data.
You may already own protection you have switched off
A low Secure Score usually means licensed Microsoft controls are sitting idle. The defence is already in your plan. It just has not been turned on yet.
The scope
A structured review of the whole tenant.
Nine assessments grouped into three areas. Together they cover the full Microsoft 365 attack surface, examined by engineers who secure it every day rather than an automated scan.
Identity and access
Entra ID Review
Admin roles, privileged access, and identity configuration examined end to end.
Identity Security Assessment
MFA coverage, legacy auth, and sign-in risk across every account.
Conditional Access Review
Policy coverage tested against device, location, and risk.
Email, data and threats
Microsoft Defender Assessment
Endpoint, identity, and email protection checked against ASD guidance.
Email Security Assessment
SPF, DKIM, DMARC, and anti-impersonation controls validated.
External Sharing Review
How data leaves the tenant through SharePoint, OneDrive, and Teams.
Posture and compliance
Secure Score Assessment
Where you sit today, why, and the highest-impact moves to lift it.
Security Baseline Assessment
Tenant configuration measured against a hardened Microsoft baseline.
Essential Eight Alignment
Where your Microsoft controls map to the ACSC Essential Eight.
Certified expertise
Certified to the Microsoft security standard.
Your Microsoft 365 Security Review is run by engineers who hold Microsoft's role-based security certifications. These are the credentials Microsoft sets for the identity, data protection, and security architecture controls your tenant depends on.
