Consolidation & Savings
Mimecast to Defender Migration
Consolidate your security stack, reduce licensing costs, and simplify operations. We deliver a zero-disruption migration from Mimecast to Microsoft Defender for Office 365.
Why Consolidate?
If you have Microsoft 365 E5 (or E3 + Security), you already own advanced mail protection. Running Mimecast in parallel adds unnecessary spend and splits your signals across two portals.
The barrier isn't technology; it's risk. We ensure you maintain policy parity (equivalent protection) and execute a safe switch-over.
Our Proven Approach
Audit & Map
We deep-dive your Mimecast policies (Impersonation, URL Rewrite, TTP) and map them to Defender equivalents (Safe Links, Anti-Phishing).
Configure & Pilot
Best-practice build in Defender mapped to Secure Score. We run a pilot cohort with side-by-side telemetry to tune false positives.
Cutover & Hypercare
After-hours MX record change with a documented rollback plan. We provide daily hypercare checks to ensure mail flow is healthy.
Archive Strategy
We help you decide what to do with your Mimecast Archive: Retain (read-only), Export, or Migrate to Microsoft Purview.
