The short version
- Each has a real cost: 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.; Unit21 it is built for fintech scale rather than card issuer scale, so organisations reaching very high transaction volumes generally re-evaluate against heavier platforms and face a migration.
- They diverge on capability: Silent Eight covers Alert adjudication, Unit21 covers No-code rule builder.

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.
Unit21
- It is built for fintech scale rather than card issuer scale, so organisations reaching very high transaction volumes generally re-evaluate against heavier platforms and face a migration.
- No-code rule authoring shifts power to the risk team, which is the point, but without governance it produces rule sprawl that nobody can explain to an examiner two years later.
- Detection quality depends on the signals you feed it, so a thin integration produces thin results and the platform cannot compensate with proprietary consortium data the way larger vendors do.
- Pricing is quoted by volume with an annual commitment, so a fintech whose growth stalls pays for headroom it did not use.
- SAR filing coverage is oriented to United States FinCEN reporting, so firms filing in the United Kingdom, European Union or Asia handle those submissions outside the tool.

Answered from the vendors’ own pages
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.
Unit21: Do we need engineers to run it?
Only for the initial data integration. After that the design intent is that risk and compliance staff author and deploy rules themselves.
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.
Unit21: Does it file SARs?
Yes, it generates and electronically files suspicious activity reports to FinCEN. Non-US regimes are not covered to the same depth.
Silent Eight: Where is the company based?
Singapore, with offices in New York, London and Warsaw.
Unit21: Can we test a rule before it goes live?
Yes. Backtesting against historical data to see projected alert volume is one of the more useful parts of the product, because alert volume is the real cost.
