The short version

  • Only Endor Labs has a free tier, so it costs nothing to try first.
  • Each has a real cost: Endor Labs pricing requires contacting sales, no transparent rates; 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: Endor Labs covers AI coding agent governance, 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.

Endor Labs

  • Pricing requires contacting sales, no transparent rates
  • Developer tier lacks UI and historical scan data
  • Free tier limited to local scanning only
  • Seat-based model may become expensive for large teams

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.

Answered from the vendors’ own pages

Endor Labs: What is the difference between Endor Labs Developer and paid tiers?

Developer tier is free and provides local scanning via MCP server with read-only vulnerability access and no UI. Paid tiers (Core and Pro) add team features like policy enforcement, enterprise integrations, reporting, and scan history.

Source
Silent Eight: Does Silent Eight replace our screening system?

No. It consumes alerts from your existing screening and monitoring systems and decides them. The detection layer stays where it is.

Endor Labs: How does Endor Labs define seats for pricing?

Seats are calculated per contributing developer (those with commits in monitored repositories within the last 90 days). Volume discounts apply as team size grows.

Source
Silent Eight: Will a regulator accept AI closing alerts?

It depends on your jurisdiction and your model governance evidence. Banks typically run extended shadow mode first and phase auto-closure by alert type.

Endor Labs: Does Endor Labs support on-premises deployment?

The platform is cloud-based SaaS by default. Enterprise customers should contact sales to discuss custom deployment options.

Silent Eight: Where is the company based?

Singapore, with offices in New York, London and Warsaw.
