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.

Vanta

  • No published pricing for any tier; all plans require requesting a demo and contacting sales
  • Essentials tier limited to one compliance framework; organisations needing multiple frameworks must upgrade to higher tiers
  • Plus and Professional tiers feature unclear differentiation; specific pricing and included questionnaires not published
  • Enterprise pricing fully custom; no transparency on costs or what features are included
  • AI questionnaire automation capped at 25 annually in Plus tier, only 144 annually in Professional tier
