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.; Vanta no published pricing for any tier; all plans require requesting a demo and contacting sales

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.
Vanta
- No published pricing for any tier; all plans require requesting a demo and contacting sales
- Essentials tier limited to one compliance framework; organisations needing multiple frameworks must upgrade to higher tiers
- Plus and Professional tiers feature unclear differentiation; specific pricing and included questionnaires not published
- Enterprise pricing fully custom; no transparency on costs or what features are included
- AI questionnaire automation capped at 25 annually in Plus tier, only 144 annually in Professional tier

Questions people ask
- Is OWASP ZAP or Vanta better?
- Neither clearly leads. OWASP ZAP starts at Free and Vanta at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, OWASP ZAP or Vanta?
- OWASP ZAP has a free tier; the other does not. Paid plans start at Free for OWASP ZAP and On request for Vanta.
- Does OWASP ZAP or Vanta run on more platforms?
- OWASP ZAP runs on Desktop, Cli, Api. Vanta runs on Web, API.
- Can I use OWASP ZAP for free?
- Yes. OWASP ZAP has a free tier, so you can try it without paying. Vanta 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 Vanta is typically brought in for.
- What can OWASP ZAP do that Vanta cannot?
- OWASP ZAP covers Intercepting proxy, Passive scanner, Active scanner, AJAX spider.
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.
Vanta: How many compliance frameworks does Vanta support?
Vanta supports 35+ compliance frameworks including SOC 2, ISO 27001, HIPAA, GDPR and custom frameworks.
SourceOWASP 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.
Vanta: Does Vanta automate questionnaires?
Yes. Vanta's AI Agent can automate questionnaire completion, with the number of annually supported questionnaires varying by plan (25 in Plus tier, 144 in Professional tier).
SourceOWASP 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.
Vanta: How many integrations does Vanta support?
Vanta integrates with 300+ pre-built system connections and supports over 90% automation of compliance tasks through these integrations.
SourceOWASP 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.
