Microsoft 365 Security Baseline: Entra, Intune & Defender

Identity is the new perimeter

Microsoft 365 is powerful, but out of the box it isn't fully hardened. A security baseline turns your tenant into a defensible platform where identity governs everything.

Microsoft Entra ID authenticates every user and app. Get this right and everything downstream inherits your policy.

• Enforce MFA for all users — no exceptions, including admins.
• Block legacy authentication protocols (SMTP AUTH, Basic Auth).
• Conditional Access: require compliant devices and trusted locations.
• Protect and monitor privileged roles with PIM.

Device management with Intune

Intune enforces encryption, screen locks, and OS compliance — and can block non-compliant devices from touching company data via Conditional Access integration. See our Intune deep-dive for Autopilot and app deployment details.

Threat protection with Defender

Defender for Office 365 (Safe Links / Safe Attachments) and Defender for Endpoint stop phishing and malware before they reach users. Pair with our email security guide for DMARC enforcement and BEC protection.

Data protection with Purview

Sensitivity labels and DLP prevent accidental oversharing of regulated data — essential for HIPAA and financial clients. Labels travel with documents, not just the container.
