The short version

  • Each has a real cost: GNAT Pro no pricing published on website; requires contacting AdaCore directly for quotes; 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.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

GNAT Pro

  • No pricing published on website; requires contacting AdaCore directly for quotes
  • Vendor indicates per-user, per-year subscription model but does not disclose specific costs

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catalogue is smaller than the market leader, which means more of the data inventory is maintained by hand and drifts out of date between reviews.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