Microsoft 365 is where your organisation emails, collaborates and stores files — which makes it a prime target. Many tenants still allow legacy authentication, lack conditional access or have never reviewed external sharing. Mavinz provides Microsoft 365 security and tenant hardening that turns your licences into real protection.
We assess your tenant against Microsoft Secure Score and recognised benchmarks such as the CIS Microsoft 365 Foundations Benchmark, then configure Microsoft Entra ID, Defender for Office 365, Intune, Purview and SharePoint/OneDrive settings in a planned, low-disruption sequence.
Why tenant hardening is essential
Account takeover through phishing and password reuse remains one of the most common causes of business email compromise. Strong identity controls and email protection stop most of these attacks.
Phishing-resistant MFA and conditional access
Safer email with Defender protections
Information protection on sensitive files
Measurable improvement in Secure Score

Microsoft 365 Security FAQs
