1Security Microsoft Alerts Tool is a Microsoft 365-focused security alerting and monitoring platform that consolidates alerts from across the Microsoft 365 ecosystem into a unified alert center. It combines Microsoft Defender anomaly detection signals with 1Security's own permission monitoring to provide enriched, contextualized alerts. The tool correlates alerts with sensitivity labels and permission data to help security teams distinguish routine access changes from genuine incidents involving confidential or regulated data. It provides a permission and sharing explorer that maps who can access what and why—covering direct assignments, groups, and sharing links—without requiring CSV exports or portal navigation. Real-time notifications are triggered when high-risk activity or credential theft attempts are detected. Alerts are prioritized by impact and sensitivity, and each alert includes an audit trail detailing participants, affected assets, and risk surface. The tool also provides oversight for Microsoft Copilot and connected AI applications, surfacing potential data exposures when AI tools access labeled or sensitive content. Automated remediation workflows can be triggered in response to alerts, such as disabling guest access, revoking sharing links, or notifying owners via Teams. The platform supports compliance mapping to ISO 27001, GDPR, HIPAA, and SOC 2 frameworks and is positioned as a complement to—not a replacement for—Microsoft Purview, DLP, and Defender. It targets banks, insurance firms, universities, public sector organizations, and enterprises.
