Ontinue ION for Enhanced Phishing Protection is an add-on service to the Ontinue ION MXDR platform that extends managed detection and response capabilities to cover user-reported phishing emails. The service combines hardened email security controls with automated triage and 24/7 expert-led investigation to address phishing attempts that bypass existing filters. Key functional areas include: - Email Security Controls: Hardens Microsoft Defender for Office 365 configurations to block phishing emails before they reach user inboxes. - Automated Triage & Investigation: Multi-layer automation filters out false positives while enriching and investigating confirmed phishing emails within minutes. - Expert-Led Investigation: 24/7 analyst-driven investigation handles complex phishing incidents that require human judgment. - Automated Response: Executes email-specific response actions at machine speed when pre-authorized through defined Rules of Engagement. - Escalation Management: Routes complex incidents to designated contacts via preferred communication methods when response approval is needed. The service is designed to operationalize Microsoft Defender for Office 365 on behalf of the customer, handling the investigation of user-reported phishing attempts end-to-end. It integrates with the broader ION MXDR service and is intended to reduce the operational burden on internal security teams by absorbing the volume of user-reported phishing submissions.
