API & Integrations - CrowdStrike Threat Share URL Enhancements - Feb 2026

Service Update

Availability	February 9th, 2026
Product(s)	Email Security Cloud Gateway (CG)
Who's affected	Email Security Cloud Gateway, Administrators

Overview

Mimecast is pleased to announce two changes to our CrowdStrike Threat Share integration.

What's changing

• URL Blocking in Mimecast: Use domains from CrowdStrike's IOC Management List, or alerts to block matching URLs with URL Protection. This can be used alongside or in place of Message Remediation options to remove messages.
• Remediation options moved under the indicator being shared: This UI change makes a more uniform set of actions to perform with their associated indicator type, rather than being a separate section dedicated to Message Remediation.

These changes make threat sharing with CrowdStrike both more powerful and easier to understand configuration options.

Recommended actions

Nothing needs to be done as a result of these changes.
