Where each one falls short

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

Auth0

  • Free tier limited to 25,000 monthly active users, requiring upgrade for growth beyond that
  • Advanced features like MFA and RBAC only available on paid Essentials tier and above
  • Ownership by Okta introduces risk that independent product roadmap may change

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catalogue is smaller than the market leader, which means more of the data inventory is maintained by hand and drifts out of date between reviews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

Auth0 was acquired by Okta in May 2021 for $6.5 billion. It now operates as a subsidiary business unit within Okta, but maintains its own brand and operations.
