Microsoft Defender for Office 365 — features we configure & manage

Safe Links

Every URL in every email, Teams message, and Office document is scanned in real time when clicked — not just at delivery. Zero-day phishing URLs blocked even after passing initial filtering.

Safe Attachments

Every attachment is detonated in an isolated sandbox environment before delivery. Malicious files — including zero-day malware — are blocked before they reach inboxes.

Anti-Phishing AI

Machine learning models detect spear phishing, executive impersonation, and brand impersonation. Far more effective than signature-based filtering for targeted attacks.

Anti-Spoofing & Impersonation

Detects emails impersonating your executives, key suppliers, and trusted domains — even when the sender's display name looks legitimate.

Threat Explorer

Real-time visibility into email threats targeting your organisation. Coreitech's analysts use Threat Explorer to investigate, hunt, and remediate email incidents.

Attack Simulation Training

Defender for Office 365 Plan 2 includes Microsoft's Attack Simulator — realistic phishing simulations with built-in training for staff who click.
