Hidden Costs Breakdown

1

Mid-Contract True-Up Charges

medium overage

Mimecast monitors endpoint count and will true you up mid-contract if they detect you're over your license count. However, this doesn't work in reverse - if your headcount falls, you don't get credited back.

They will have their pound of flesh, they are not very flexible with pricing. The price on the quote is what you pay and they can and will true you up mid contract if they detect you over your licence count. Of course, that does not work in reverse if your headcount falls past true up.

2

Proofpoint Integration API Dependency

medium integration

To integrate Mimecast with Proofpoint for IOC sharing, you may need to purchase a separate Threat Intel module. Notably, the Mimecast API that other vendors use is free, but Proofpoint requires a paid dependency.

I believe this threat intel dashboard is the module that includes a purchase dependency for the API that Proofpoint uses to share the latest IOCs with Crowdstrike (obviously neither vendor mentions this in presales). Notably Mimecast uses a different Crowdstrike API which is free.

Support Tier Costs

medium support

Gold support is considered a requirement by experienced users to get minimal hold times and competent help. Email support is described as useless without it. The additional support costs are not always transparent upfront.

Mimecast email support is useless, you need to call. I find most of the people I've gotten on the phone are decently competent. I have Gold support (consider it a requirement to get Gold support) so hold times are minimal.

Be careful in the pricing...they like to tack on more support costs than you really need.

Implementation and Setup Costs

low implementation

Mimecast charges setup fees that may not be disclosed upfront. These can sometimes be waived through negotiation, particularly if you position an expedited purchase decision aligned with the sales team's quarter-end.
