Where each one falls short

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

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.

Zscaler Internet Access

  • The pricing page names two base tiers, Essentials Platform and Zscaler Platform, plus modular add ons including three Digital Experience Monitoring tiers, but publishes no dollar figures anywhere and routes buyers to a demo request for cost
