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.

Stytch

  • Free tier limited to 10,000 monthly active users; scaling beyond this requires custom pricing negotiation
  • Fraud prevention capabilities billed at $0.005 per fingerprint for usage exceeding 10,000 free checks
  • Additional SSO or SCIM connections beyond the 5 included in free tier cost $125 each
  • Brand customisation and email removal require one-time payment of $99
  • HIPAA and advanced fraud protection only available in Enterprise tier
  • No native UI builder; requires custom frontend development for fully-branded auth flows
