Defender for Office 365
Safe Attachments, Safe Links, and impersonation protection — configured, tuned, and tested against your real mail flow.
One Phishing Click Is Still the Most Common Breach
Ninety percent of mid-market breaches start with an email. A link that looks legitimate. An attachment from a known vendor. A CEO fraud message sent to accounting on a Friday afternoon. Exchange Online's built-in anti-spam catches the obvious — it does not catch the targeted ones.
This is not a failure of your IT team. Defender for Office 365 Plan 1 is included in every M365 Business Premium and M365 E5 license. What is missing: the Preset Security Policies need tuning, anti-phishing impersonation protection needs VIP and domain lists, Safe Attachments needs an unblock path for false positives. Without a structured rollout, the first broken workflow gets reported to the helpdesk, the policy gets disabled, and the protection is gone.
Traditional consulting for MDO? A week of billable hours for what is mostly clicking through admin-center wizards. The consultant leaves. Your team does not know why a specific setting was chosen.
