  • They diverge on capability: Mimecast covers Advanced threat detection, Sumsub covers Document verification.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Mimecast

  • No pricing is published for any product or plan, and every route ends at a quote or demo request
  • The platform is split into separately sold products for email security, awareness training, data protection and governance
  • Collaboration threat protection, DMARC analysis, incident response and email archiving are all further add ons on top of those

Sumsub

  • The published per-verification rate is undercut by a monthly minimum of 149 or 299 dollars, so low volume businesses pay a much higher effective rate than the headline suggests.
  • You are billed per verification attempt in most configurations, meaning applicant drop-off and resubmissions cost money without producing a customer.
  • Pass rates and document support vary noticeably by country, and a market that works well in Europe can produce materially worse rejection rates in parts of Africa and South East Asia.
  • The AML screening tier bundles list coverage that large institutions would normally buy separately and tune, giving less control over match thresholds than a dedicated screening vendor.
  • The company originated in Russia before restructuring to a UK entity, and some financial institutions still raise that history in vendor risk review, which can slow or block procurement at conservative banks.
