Key Takeaways

• Most Microsoft 365 tenants underuse built-in security, leaving identities, email, and data unnecessarily exposed.
• Enforcing MFA & Conditional Access across all users is the single biggest security improvement.
• Defender for Office 365, Secure Score, and DLP drastically reduce phishing, data loss, and compliance risk.
• Privileged Identity Management and advanced audit tools are essential to protect admins and sensitive operations.

• Microsoft 365 Management turns fragmented settings into a secure, optimised, continuously managed environment.

Microsoft 365 (M365) has become the backbone of business productivity, from small enterprises to global corporations. Yet most organisations don’t realise that the default setup of Microsoft 365 is not fully secure!

Every day, cybercriminals target emails, OneDrive files, and Teams channels to steal sensitive information. Research by Egress reveals that 85% of organizations using Microsoft 365 have suffered email data breaches in the last 12 months! The Reason? Many of the affected individuals have misconfigured security settings, leaving them exposed to data loss and ransomware attacks.

So, if you’re relying on M365 for your organisation’s collaboration and data storage, it’s time to choose yourself and take control of your security stack. In this blog, we highlight 7 underused Microsoft 365 security features that can help you prevent breaches, protect your licence investment, and strengthen your cyber defences.

Why Microsoft 365 Security Matters More Than Ever?

The cyber threat landscape is evolving faster than ever! SMEs and enterprises alike are under constant attack. Reports from the Cyber Security Breaches Survey indicate that 93% of businesses in the United Kingdom experienced a phishing cybercrime this year, with the majority involving the compromise of Microsoft 365 accounts.

While Microsoft handles the infrastructure security of the cloud, you — the customer — are responsible for data protection, access controls, and policy enforcement.

That’s where Fortray, a UK-based Managed IT Service Provider (MSP), steps in to help you bridge the gap. Our Microsoft 365 management services ensure you don’t just own the licence — you own the security!
