Frequently Asked Questions
How many NIST 800-171 controls does Mimecast cover?
Mimecast covers 7 of 110 NIST 800-171 controls (6%), with 2 partially covered and 3 gaps.
Can Mimecast alone satisfy CMMC Level 2?
No single tool covers all 110 NIST 800-171 controls. Mimecast covers 6% and should be part of a layered security stack addressing the remaining controls.
What controls does Mimecast not cover?
Mimecast does not cover controls ia-3-5-1, pe-3-10-1, cm-3-4-1. These require supplementary solutions such as physical security controls, additional access management, or media protection tools.
