The short version

  • Only Bitwarden has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bitwarden the integrated TOTP authenticator, encrypted file attachments, vault health reports and Emergency Access are all withheld from the free plan and need Premium at $1.65 per month; 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: Bitwarden covers Unlimited password storage, 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.

Bitwarden

  • The integrated TOTP authenticator, encrypted file attachments, vault health reports and Emergency Access are all withheld from the free plan and need Premium at $1.65 per month
  • Free accounts can share vault items with one other Bitwarden user and no more
  • File storage is capped at 5 GB on Premium and 5 GB personal plus 5 GB family on the Families plan
  • Two-step login accepts up to 10 hardware security keys per account
  • The Families plan is capped at 6 people, so a seventh member means moving to a Teams subscription at $4 per user per month

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.

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.
