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 on Microsoft Secure Score 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.

In their words
Trusted by teams who take security seriously.
We work with Australian community housing providers, education and not-for-profit organisations, and professional and financial services firms, teams that run on Microsoft 365 and can't afford to get security wrong.
We engaged IronSights to help us with an Akira ransomware incident that impacted one of our clients. They were great to work with and jumped in quickly to help us investigate what had happened and get the client back up and running. Ryan and the team worked well alongside our engineers and kept things moving during a pretty stressful incident. Would definitely recommend them to other MSPs needing an extra set of hands or specialist help with ransomware recovery.
Brett
Director · Managed Service Provider
We recently worked with IronSights in relation to our Financial Services AFSL cybersecurity audit requirements and were extremely impressed with their professionalism and expertise. The team provided clear guidance throughout the process, assisted us with the Microsoft claim application, and ensured everything was completed smoothly and efficiently. Their knowledge of cybersecurity compliance and AFSL audit requirements gave us confidence that our business was meeting the necessary standards.
Addy
Director · AFSL Financial Services Firm
Not all heroes wear a cape. These guys dropped what they were doing and were on the next flight to not only save our butt but crucially recover forensic IT info about our ransomware attack and help us get back up. We can’t praise Ryan and team highly enough for their 6 star effort.
