The short version
- Each has a real cost: Transmit Security pricing is not published, so it cannot be compared early against competitors that post per monthly active user rates, and the eventual quote often mixes per-user and per-transaction units.; 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: Transmit Security covers Passwordless authentication, Unit21 covers No-code rule builder.
- 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.
Transmit Security
- Pricing is not published, so it cannot be compared early against competitors that post per monthly active user rates, and the eventual quote often mixes per-user and per-transaction units.
- Migrating a live consumer identity base is a high risk project, and credential migration constraints mean some users must re-register, which shows up as measurable churn.
- The vendor is smaller than the identity incumbents, so the partner and systems integrator pool is thinner and staffing a large programme is harder.
- Workforce identity is not the focus, so an organisation wanting one vendor for employees and customers will still run two platforms.
- The fraud detection value depends on traffic volume feeding the models, so a smaller deployment gets less benefit from exactly the capability that justified choosing it over a plain identity provider.
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
Transmit Security: Do we have to replace our existing identity provider?
No. The services are composable, so detection and response or verification can be adopted alongside an existing provider such as Okta or Entra ID.
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.
Transmit Security: Is fraud detection an extra licence?
It is a separate service, but it is designed to run inside the authentication flow rather than as a bolted-on second vendor. Confirm which services are in your quote.
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.
Transmit Security: Is there a way to try it?
Yes, a free developer tier exists for evaluation, though production use is an enterprise agreement.
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.
