The short version

  • Each has a real cost: GNAT Pro no pricing published on website; requires contacting AdaCore directly for quotes; ThetaRay unsupervised models are harder to justify to an examiner than explicit rules, and some regulators still expect documented threshold logic, which can force you to run both systems.
  • Prices and features above were last checked on 1 September 2026.

  • A payment institution entering a high-risk corridor where existing thresholds were calibrated on domestic trafficnot GNAT Pro

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

ThetaRay

  • Unsupervised models are harder to justify to an examiner than explicit rules, and some regulators still expect documented threshold logic, which can force you to run both systems.
  • The alert reduction claim depends heavily on your data, so a parallel run is essential and adds months and cost before you can decommission the incumbent.
  • Coverage is strongest in cross-border and correspondent flows; institutions whose risk is domestic retail fraud will find the fit weaker than a general-purpose monitoring platform.
  • It is a smaller vendor than the incumbents, so integration connectors into legacy core banking systems are often bespoke work rather than a supported adapter.
  • Model retraining and tuning are vendor-led, which means changing detection behaviour is a support conversation rather than something your own analysts can do that afternoon.

Questions people ask

Is GNAT Pro or ThetaRay better?
Neither clearly leads. GNAT Pro starts at On request and ThetaRay at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, GNAT Pro or ThetaRay?
GNAT Pro starts at On request and ThetaRay at On request.
Does GNAT Pro or ThetaRay run on more platforms?
Both run on Web, so platform support will not decide this one for you.
What is GNAT Pro best used for?
GNAT Pro is most often used for building certified avionics software meeting do-178b/c standards, developing automotive embedded systems with iso-26262 compliance, integrating ada, c/c++, and rust components in single codebase, managing software supply chain vulnerabilities and sboms. Of those, building certified avionics software meeting do-178b/c standards and developing automotive embedded systems with iso-26262 compliance are not what ThetaRay is typically brought in for.
What can GNAT Pro do that ThetaRay cannot?
ThetaRay covers Unsupervised detection, Cross-border focus, Sanctions screening, Alert triage.

Answered from the vendors’ own pages

GNAT Pro: How much does GNAT Pro cost?

GNAT Pro pricing is not published on the website. Customers must request a pricing quote by contacting AdaCore directly or speaking with a GNAT Pro expert.

Source
ThetaRay: Does it replace a rules engine entirely?

Rarely on day one. Most institutions run it alongside existing rules during a parallel period, and some keep specific regulator-mandated rules permanently.

GNAT Pro: What is GNAT Pro licensing model?

GNAT Pro is sold on a per-user, per-year basis with no license locks. Customers can request pricing for their specific needs.

Source
ThetaRay: Where is the data processed?

SaaS runs on Microsoft Azure with regional deployment options, which is the mechanism for meeting data residency conditions in regulated markets.

ThetaRay: Is sanctions screening included?

Screening is available on the same platform but licensed as part of the commercial package rather than bundled by default. Confirm it is in your quote.
