Overview
Mimecast is pleased to announce Remediation 2.0, a complete architectural redesign of how we respond to email threats. Built on modern cloud infrastructure, Remediation 2.0 delivers the speed, reliability, and scale you need to protect your organization.
What's changing
-
Faster Remediation: Remediation 2.0 removes email threats in approximately 10 seconds with time scaling for larger remediation volumes. With Remediation 2.0, threats are neutralized before they can spread across your organization. Previously, large batches could take minutes or longer.
-
How it works:
Built on modern AWS architecture with dynamic scaling, eliminating the resource bottlenecks of legacy systems.
-
How it works:
-
Rebuilt for Modern Email Platforms: Seamlessly integrates with Microsoft 365, Google Workspace, and Exchange environments using the latest platform capabilities.
-
How it works:
Built on modern platform APIs across Microsoft 365, Google Workspace, and Exchange on-premises for faster, more secure remediation.
-
How it works:
-
Unified Remediation Experience: Whether you're using Email Security - MX or API Email Security API, you get the same fast, reliable remediation experience. Consistent performance across all deployment models means predictable response times, no matter your configuration.
-
How it works:
Single, streamlined remediation engine for all customer environments.
-
How it works:
-
Complete Threat Elimination (Microsoft 365): Remediation 2.0 removes the entire message body, attachments, and links in a single action. There are no partial removals. For Microsoft 365 environments, removing the entire message guarantees nothing is left behind to cause harm.
- How it works:
For Microsoft 365, Remediation 2.0 operates at the message level through Microsoft Graph, replacing the previous approach of targeting individual message components. One action for complete removal.
- How it works:
Benefits
- 10-Second Remediation: Consistent sub-10-second response times for standard remediation sizes with time scaling for larger remediation volumes.

- Future-Proof Platform: Built on Microsoft Graph and modern APIs.
- Unified Architecture: Same experience for Email Security - MX and Email Security - API customers.

- Smart Protection: Hash matching prevents accidental remediation of legitimate files.
- Infinite Scale: Handles concurrent remediation requests without performance degradation.
Recommended actions
Nothing needs to be done as a result of these changes. The user interface and workflows remain the same. You'll simply notice faster remediation times.
