The short version

  • Each has a real cost: Mimecast no pricing is published for any product or plan, and every route ends at a quote or demo request; TrustArc the software layer is generally shallower than OneTrust, particularly automated data discovery across large heterogeneous estates, so organisations with sprawling infrastructure often still need a separate discovery tool.
  • They diverge on capability: Mimecast covers Advanced threat detection, TrustArc covers Nymity Research.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Mimecast

  • Email security filtering against phishing and targeted attacksnot TrustArc
  • Email archiving, continuity and compliance for organisationsnot TrustArc

TrustArc

  • A privacy programme being audited that needs documented maturity benchmarking against a recognised framework of programme activitiesnot Mimecast

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

TrustArc

  • The software layer is generally shallower than OneTrust, particularly automated data discovery across large heterogeneous estates, so organisations with sprawling infrastructure often still need a separate discovery tool.
  • The integration catalogue is smaller than the market leader, which means more of the data inventory is maintained by hand and drifts out of date between reviews.
  • Certification services are sold separately from the platform subscription, so the seal that is often the reason for choosing TrustArc is an extra line item and an extra annual renewal.
  • Reported contract values vary enormously by module mix and organisation size, and the absence of published pricing means smaller buyers have no anchor and routinely discover the entry price is higher than expected.
  • TrustArc stays inside privacy, so organisations that later want third-party risk, security compliance or ethics reporting on the same platform will be running a second vendor anyway.
