The short version
- Each has a real cost: Resolver kroll ownership since 2022 means the product is sold alongside risk consulting services, so buyers who want software with no services attach should expect that conversation and should price the licence separately in negotiation.; 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: Resolver covers Incident management, 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.
Resolver
- Kroll ownership since 2022 means the product is sold alongside risk consulting services, so buyers who want software with no services attach should expect that conversation and should price the licence separately in negotiation.
- Configuration flexibility comes at the cost of implementation time, with deployments commonly running several months and typically requiring vendor or partner services, so the first-year cost is well above the annual licence.
- Module-based pricing means the platform gets expensive quickly once you add audit, compliance and continuity to a security-led purchase, and modules bought later rarely carry the discount of the original deal.
- The IT and cyber compliance side is thinner than dedicated tools, so organisations chasing SOC 2 or ISO 27001 evidence automation will find it does not replace a Drata or Vanta.
- Reporting is capable but the drag and drop builder has a real learning curve, and organisations that do not train an internal administrator end up raising support tickets for changes that should be self-service.
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
Resolver: Who owns Resolver?
Kroll, which acquired it in 2022. It is marketed as a Kroll business and sold alongside Kroll risk and investigations services.
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.
Resolver: What does Resolver cost?
Pricing is not published. It is quoted by module and user count on an annual or multi-year enterprise agreement, with implementation charged separately.
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.
Resolver: Is Resolver a SOC 2 compliance tool?
No. It is a risk, incident and investigations platform. Automated evidence collection for security certifications is not its strength.
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.
Resolver: How long does implementation take?
Months rather than weeks for a multi-module deployment, and most customers use vendor or partner services to configure it.
