Microsoft Defender for Office 365 Plan 1

Stop email-borne threats before they interrupt staff, volunteers, or donors. Microsoft Defender for Office 365 Plan 1 adds targeted protection for Microsoft 365 environments, helping organizations identify malicious attachments, unsafe links, and suspicious messages before they spread across the tenant. For non-profits, the annual paid model provides predictable licensing while supporting a security posture that fits constrained budgets and lean IT teams. This plan is designed for organizations that need more than basic spam filtering but do not require the full breadth of advanced enterprise threat management. It strengthens the security layer around Exchange Online and related Microsoft 365 collaboration tools, helping reduce the chance of credential theft, ransomware delivery, and account compromise. The result is faster response, fewer risky clicks, and better protection for high-value communications. Because it is part of the Microsoft ecosystem, deployment aligns naturally with existing Microsoft 365 administration and policy workflows. That makes it easier to standardize protection across users while keeping procurement simple through annual non-profit pricing. For teams responsible for safeguarding sensitive communications, donor records, and internal coordination, this license delivers focused protection where it matters most.
