Where each one falls short

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

Silent Eight

  • Automated disposition has to clear model risk governance and a regulator, and the shadow running period before auto-close is permitted can consume most of the first year of the contract.
  • It does not improve detection, so an institution with a poorly tuned monitoring system automates the handling of bad alerts rather than fixing why they exist.
  • Pricing is tied to alert volume, which means efficiency gains elsewhere that reduce alerts also reduce the vendor bill in a way sales teams structure minimums against.
  • The headcount saving is only realised if the institution actually reduces the analyst pool, and many banks redeploy rather than cut, leaving the business case unrealised on paper.
  • As a mid-sized private vendor serving tier one banks, concentration risk cuts both ways; the loss of one large client materially affects the company, and buyers should ask about financial stability during diligence.

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
