The short version

  • Only Wireshark has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Wireshark free and open source under the GNU GPL; downloadable without paying any license fee, no commercial tier
  • They diverge on capability: Unit21 covers No-code rule builder, Wireshark covers Deep packet inspection.
  • 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.

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.

Wireshark

  • Free and open source under the GNU GPL; downloadable without paying any license fee, no commercial tier

Answered from the vendors’ own pages

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.

Wireshark: Is there a cost to download and use Wireshark?

No, Wireshark is completely free. It's distributed under the GNU General Public License version 2, making it "free software" with no demo limitations. The full version is available at no cost.

Source
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.

Wireshark: What support options are available for Wireshark users?

Wireshark offers multiple support channels including mailing lists, an active Discord community, the Ask Wireshark Q&A platform, comprehensive documentation, a user guide, and developer resources for those needing technical assistance.

Source
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.

Wireshark: Are there different pricing tiers or subscription levels?

Wireshark does not offer pricing tiers or subscriptions. There is one free version available to all users regardless of use case, personal, professional, or organizational.
