Protect Windows, macOS, iOS, and Android endpoints with Microsoft Defender for Business, a business endpoint security service that combines preventive protection with endpoint detection and response. Security administrators can investigate alerts, review device exposure, and respond to threats from the Microsoft security management experience. Automated investigation and remediation help reduce manual response work when malicious activity is detected. B00A73FE00D6-1Y is the annual CSP ordering option carrying NFP staff pricing. It applies the Microsoft Defender for Business service to an organization’s endpoint-security environment rather than providing a physical appliance, media, or hardware component. The subscription format suits organizations managing employee devices through a centralized security operation and needing consistent endpoint protection across supported operating systems. Within the Defender for Business subscription family, this option is distinguished by its NFP staff pricing designation and 1-year CSP term. Those identifiers matter when selecting licensing for qualified nonprofit staff rather than choosing a general commercial purchasing option. The service focuses on business endpoint protection, detection, investigation, and remediation workflows, giving administrators a single security service for device-focused threat monitoring and response.
