The short version

  • Only Helm has a free tier, so it costs nothing to try first.
  • Each has a real cost: Helm licensed under Apache License 2.0 per the project's GitHub repository (helm/helm LICENSE); as open source software it has no paid tier or vendor price to compare; 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.

What people use each for

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

Helm

  • Kubernetes package manager and deployment toolnot ThetaRay

ThetaRay

  • A correspondent bank that cannot see the ultimate originator and needs behavioural signals rather than counterparty listsnot Helm
  • A cross-border payments fintech whose rules engine produces more alerts than its compliance team can clearnot Helm
  • A bank under a regulatory consent order needing demonstrable improvement in detection within a fixed periodnot Helm
  • A payment institution entering a high-risk corridor where existing thresholds were calibrated on domestic trafficnot Helm

Where each one falls short

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

Helm

  • Licensed under Apache License 2.0 per the project's GitHub repository (helm/helm LICENSE); as open source software it has no paid tier or vendor price to compare
  • Contributors must sign commits under the Developer Certificate of Origin to have them accepted, per helm.sh, a process requirement not all Kubernetes tools impose

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.

Answered from the vendors’ own pages

Helm: How much does Helm cost?

Helm is free and open-source. It is a graduated project in the Cloud Native Computing Foundation (CNCF) with no commercial pricing model.

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.

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.
