Frequently Asked Questions

This is a full proof of value, not just a passive scan. You'll get real-time monitoring in Monitor Mode, 30-day historical threat analysis, and complete access to the Mimecast platform during the trial period, including Collaboration Security, DMARC Analyzer, Awareness Training, and Sync & Recover.

No. Mimecast deploys via Microsoft 365 API — there are no MX record changes, no DNS modifications, and no impact on email delivery or user experience.

No problem. You can start with API-based deployment for your proof of value and transition to MX-based gateway deployment at onboarding.

If you start and keep the trial in Threat Scan only mode, there are no steps necessary to remove the trial. Otherwise, it’s just a few simple steps.
