Overview

Mimecast is pleased to introduce Cisco Duo integration, this integration will enhance your organization’s security by providing deeper visibility into identity-based threats. The Duo Integration allows Mimecast customers to ingest event data from Duo’s Identity and Access Management (IAM) platform, enabling improved detection and response to suspicious login activity and identity-related attacks.

What's changing

• Integration Availability: The Duo Integration is now available in the Mimecast Integration Hub.
• Expanded Event Coverage: The integration supports ingestion of both Duo Authentication events and, where licensed, Trust Monitor events. This includes detection of credential stuffing, anomalous logins, device anomalies, and more.
• Real-Time Data: Only events generated after the integration is enabled are ingested, ensuring up-to-date visibility without impacting historical attack factor scores.
• Simplified Configuration: Customers can now easily configure the integration using their Duo Admin API credentials directly within the Mimecast platform.
