The short version
- Only OWASP ZAP has a free tier, so it costs nothing to try first.
- Each has a real cost: OWASP ZAP authenticated scanning of modern single-page applications is the hard part and ZAP makes you build it by hand: session handling, token refresh and login scripts are configured per application, and a misconfigured session means the scanner logs itself out and reports a clean result for pages it never reached.; Quantexa pricing is never published and lands in the seven figure range annually for a tier one deployment, so it is out of reach for mid-sized institutions no matter how well the analytics would fit.
- They diverge on capability: OWASP ZAP covers Intercepting proxy, Quantexa covers Entity resolution.
- Prices and features above were last checked on 1 September 2026.

What people use each for
The jobs each tool is most often brought in to do.
OWASP ZAP
- Adding a baseline security scan to every application's pipeline where per-target commercial licensing would limit coverage to a handfulnot Quantexa
- Manual penetration testing that needs an intercepting proxy, request replay and fuzzing without a paid licence per testernot Quantexa
- Teaching developers what an attack against their own endpoint looks like, using a tool they can install themselvesnot Quantexa
- Pre-release regression scanning of an internal application that would never justify a commercial DAST subscriptionnot Quantexa
Quantexa
- A bank whose AML alert backlog is dominated by false positives and wants network context to close them fasternot OWASP ZAP
- Sanctions investigation where the sanctioned party is not the account holder but a connected director or shareholdernot OWASP ZAP
- Merging customer records across retail, commercial and wealth divisions after an acquisition to see total exposurenot OWASP ZAP
- A tax or benefits agency looking for organised fraud rings rather than individual claimantsnot OWASP ZAP
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
OWASP ZAP
- Authenticated scanning of modern single-page applications is the hard part and ZAP makes you build it by hand: session handling, token refresh and login scripts are configured per application, and a misconfigured session means the scanner logs itself out and reports a clean result for pages it never reached.
- There is no support contract in the product, so when a scan breaks the day before a release the escalation path is a GitHub issue and a community chat, which is not an answer that satisfies a delivery manager or an auditor who wants a named responsible party.
- Active scanning sends genuine attack traffic, so it can create records, trigger emails, exhaust rate limits or destabilise a fragile environment, and pointing it at production without prior agreement produces an incident rather than a test result.
- Output needs triage: passive rules generate large volumes of low-severity informational findings about headers and cookie flags that bury the few results that matter, and a team without someone tuning the rule set stops reading the report within a few sprints.
- As a dynamic scanner it can only test what it can reach, so authorisation flaws between accounts, business logic abuse and anything behind an undiscovered endpoint go unreported, and a passing ZAP scan is evidence of nothing more than the absence of the classes of bug it looks for.
Quantexa
- Pricing is never published and lands in the seven figure range annually for a tier one deployment, so it is out of reach for mid-sized institutions no matter how well the analytics would fit.
- Output quality is bounded by input data quality, and organisations without governed customer data spend the first phase of the programme fixing feeds rather than catching criminals.
- Implementation typically requires a systems integrator and runs into quarters rather than weeks, so the business case has to survive a long period with no operational benefit.
- The platform augments rather than replaces existing transaction monitoring, so you keep paying for the incumbent system alongside it and total compliance technology spend rises before it falls.
- Skills are scarce; the platform needs people who understand both Spark scale data engineering and financial crime typologies, and those people are hard to recruit and easy to lose.

Questions people ask
- Is OWASP ZAP or Quantexa better?
- Neither clearly leads. OWASP ZAP starts at Free and Quantexa at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, OWASP ZAP or Quantexa?
- OWASP ZAP has a free tier; the other does not. Paid plans start at Free for OWASP ZAP and On request for Quantexa.
- Does OWASP ZAP or Quantexa run on more platforms?
- OWASP ZAP runs on Desktop, Cli, Api. Quantexa runs on Web, Linux.
- Can I use OWASP ZAP for free?
- Yes. OWASP ZAP has a free tier, so you can try it without paying. Quantexa starts at On request.
- What is OWASP ZAP best used for?
- OWASP ZAP is most often used for adding a baseline security scan to every application's pipeline where per-target commercial licensing would limit coverage to a handful, manual penetration testing that needs an intercepting proxy, request replay and fuzzing without a paid licence per tester, teaching developers what an attack against their own endpoint looks like, using a tool they can install themselves, pre-release regression scanning of an internal application that would never justify a commercial dast subscription. Of those, adding a baseline security scan to every application's pipeline where per-target commercial licensing would limit coverage to a handful and manual penetration testing that needs an intercepting proxy, request replay and fuzzing without a paid licence per tester are not what Quantexa is typically brought in for.
- What can OWASP ZAP do that Quantexa cannot?
- OWASP ZAP covers Intercepting proxy, Passive scanner, Active scanner, AJAX spider. Quantexa covers Entity resolution, Network generation, Contextual monitoring, Investigation workspace.
Answered from the vendors’ own pages
OWASP ZAP: Is it still called OWASP ZAP?
The project left OWASP in August 2024 and is now governed by the Software Security Project, with core development sponsored by Checkmarx. The tool is now just ZAP, though most existing documentation, courses and search results still use the OWASP name.
Quantexa: Does Quantexa replace our transaction monitoring system?
No. It usually sits alongside it, adding network context to the alerts that system generates and to investigations.
OWASP ZAP: Is it free for commercial use?
Yes. It is Apache 2.0 licensed, with no per-application, per-scan or per-user cost, and it can be used and modified commercially without a licence agreement.
Quantexa: Where does our data go?
Into your own cloud tenancy in the normal deployment model. Quantexa does not require you to send customer data to a shared multi-tenant service.
OWASP ZAP: Can it replace a penetration test?
No. It automates checks for known vulnerability classes against endpoints it can reach. It does not reason about business logic, chain findings into an attack, or test authorisation between accounts, which is most of what a tester actually does.
Quantexa: How is it priced?
Not publicly. Expect an annual subscription scaled by data volume and number of use cases, plus separate implementation cost.
OWASP ZAP: Does it run in CI?
Yes, through the official Docker images and the Automation Framework, which defines scan jobs in YAML so configuration lives in the repository. A baseline passive scan is the usual starting point because it is fast and non-intrusive.
OWASP ZAP: How does it compare to Burp Suite?
Burp Suite Professional is the more polished manual testing tool and has a stronger scanner and extension ecosystem, but it is licensed per tester and Burp Suite Enterprise per target. ZAP is the better fit where cost per target is the binding constraint; many teams use both.
