Product Update: Cloud Connector Migration to Mimecast API 2.0

Mimecast and Blumira provide an integrated solution to improve detection, stop threats, enhance security insights and centralize response.

Blumira’s cloud SIEM platform ingests Mimecast data. The Mimecast Actions (logs, email activity, attachments) are available for analyst investigation – from a single interface. With our Mimecast Cloud Connectors integration, Blumira makes it easy to detect threats earlier and coordinate faster response.

Together, Mimecast and Blumira share high-fidelity indicators to help analysts quickly and accurately identify the root cause of an attack and remediate the threat. This helps security teams protect against initial infection and lateral spread that can lead to downtime, ransom demands, lost data and stolen passwords.

Update Your Blumira Mimecast Integration

We’re updating our Mimecast Cloud Connector integration, as Mimecast is updating their API from version 1.0 to version 2.0. 

What you need to know:

• Mimecast is releasing API 2.0 in June 2025
• Your Blumira logging and old integrations with Mimecast API 1.0 will not change or stop working, however, you will not be able to edit your V1 integration
• Mimecast will no longer allow API 1.0 credentials to be created, but will instead force users to create 2.0 credentials

We recommend replacing your current Mimecast cloud integration, but you have until the end of 2025 to update it before the Mimecast API 1.0 will be officially deprecated.

According to Mimecast: If you are an existing Email Security Cloud Gateway customer with active integrations, use Mimecast API 1.0. However, please make every effort to plan and schedule a migration to Mimecast API 2.0, as we will shortly announce a date for deprecation for Mimecast API 1.0.
