The short version

  • Only Infisical has a free tier, so it costs nothing to try first.
  • Each has a real cost: Infisical free tier limited to 5 identities, suitable only for small teams or evaluation; 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.
  • They diverge on capability: Infisical covers Secrets management, Silent Eight covers Alert adjudication.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Infisical

  • Free tier limited to 5 identities, suitable only for small teams or evaluation
  • Pricing tiers are per-identity, which scales costs with team size
  • Certificate management requires Enterprise plan for advanced features like wildcards
  • Privileged access tier is separate billing from secrets management

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.
