Protect staff devices against malware, ransomware, credential theft, and other endpoint threats with Microsoft Defender for Business. The service combines antivirus protection with endpoint detection and response capabilities so security personnel can investigate alerts, review affected devices, and take remediation actions from a centralized Microsoft security experience. Threat and vulnerability management helps identify software and configuration exposure that can increase endpoint risk. Defender for Business fits organizations that need managed endpoint security without operating a separate on-premises security appliance. It supports security monitoring and response workflows for business endpoints, including alert investigation, incident context, automated investigation, and remediation. The service is intended for organizations that need stronger visibility and response capability than endpoint antivirus alone provides. B00A73FE00D6 carries the NFP staff pricing designation for Microsoft Defender for Business. This subscription is a cloud service entitlement rather than a physical endpoint security appliance. Confirm the required subscription quantity, service term, and organizational eligibility before assigning coverage, particularly when adding protection to an existing Microsoft security environment or extending coverage to additional staff devices.
