The short version

  • Only Aikido has a free tier, so it costs nothing to try first.
  • Each has a real cost: Aikido free plan includes fair-usage limits on repos and container images; 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: Aikido covers Static Application Security Testing (SAST), 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.

Aikido

  • Free plan includes fair-usage limits on repos and container images
  • Pricing increases significantly with user and repository scale
  • Advanced features like penetration testing and VM scanning limited to higher tiers
  • Device protection limited to Development environments only
  • Requires multiple plan tiers for full platform coverage

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.
