Solution Overview

The integration of Mimecast’s advanced email security with SentinelOne’s MDR capabilities empowers managed security providers to deliver a more intelligent, scalable, and responsive cybersecurity service. Mimecast contributes rich email threat intelligence, such as phishing, impersonation, and malware indicators, which SentinelOne ingests to drive proactive detection, investigation, and automated response.

Stop Phishing Before It Spreads

A phishing email is detected by Mimecast. SentinelOne MDR checks if the user clicked or downloaded anything, and quickly isolates the endpoint if needed.

Catch Business Email Compromise

Mimecast flags suspicious email behavior. SentinelOne investigates and takes action if the account or endpoint is compromised.

Respond to Malware Sent by Email

Mimecast blocks or detects a malicious attachment. SentinelOne hunts for signs the malware ran on any devices and shuts it down fast if found.

Hunt and Disrupt Multi-Stage Attacks

SentinelOne MDR uses Mimecast’s threat data (like bad domains or senders) to look for related activity on endpoints, helping stop larger attacks early.
