Is Microsoft 365 secure by default?

No. Microsoft 365 security settings are not all enabled by default. Recommended security settings must be actively configured. Legacy authentication protocols, which do not support MFA, remain enabled in many tenants. Organisations that disable legacy authentication experience 67% fewer account compromises.

What is the difference between Microsoft 365 Business Standard and Premium?

Business Premium (£16.90/user/month) includes Defender for Business, Intune device management, Entra ID P1 for conditional access, and Purview DLP — none of which are available in Standard (£9.60/user/month). For businesses with security concerns, Premium is the recommended tier.

What is the most common type of cyber attack in the UK?

Phishing is the most common attack type, identified by 85% of businesses that experienced a breach (DSIT 2025). Phishing accounts for 93% of cyber crimes against businesses. AI-powered phishing has driven a 204% increase in phishing emails delivering malware in 2025.

Is Cyber Essentials certification worth it?

Organisations with Cyber Essentials certification are 92% less likely to make a claim on their cyber insurance. Certification is mandatory for UK government contracts involving sensitive data. Only 3% of UK businesses are currently certified, giving certified businesses a competitive advantage.

When to Choose Each Option

Guidance based on your business requirements.

Choose MDM When

Your business has specific requirements that favour this approach. Budget and resources align with this solution. Your existing infrastructure supports it

Choose MAM When

Your business needs a different approach. You have different budget considerations. Your team has relevant experience

Cost Considerations

Both MDM and MAM have different cost profiles. The right choice depends on your business size, existing infrastructure, and specific requirements. AMVIA can help you evaluate which option delivers the best value for your situation.

The AMVIA Recommendation

Use MDM for company-owned devices and MAM for BYOD. Microsoft Intune supports both models within a single platform — included in M365 Business Premium. AMVIA recommends a hybrid approach: full MDM on all corporate assets, with MAM-only policies applied to personal devices accessing company email and SharePoint. This is the standard we deploy for all managed clients.
