The short version

  • Only Burp Suite has a free tier, so it costs nothing to try first.
  • Each has a real cost: Burp Suite the automated vulnerability scanner is Professional only, at $499; the free Community edition is manual tools; 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: Burp Suite covers Web vulnerability scanner, 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.

Burp Suite

  • The automated vulnerability scanner is Professional only, at $499; the free Community edition is manual tools
  • BApp Store extensions require the Professional edition
  • DAST and the agentic testing product are separate enterprise offerings with no published price
  • Professional is licensed per user per year rather than perpetually

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.
