The short version

  • Only OWASP ZAP has a free tier, so it costs nothing to try first.
  • Each has a real cost: Azure Government restricted to US government entities, their solution providers and contractors handling government data, with Microsoft validating eligibility first; 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.
  • They diverge on capability: Azure Government covers FedRAMP High Authorized, OWASP ZAP covers Intercepting proxy.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

  • Systems needing FedRAMP High, DoD IL2 to IL5, CJIS or ITAR authorisationnot OWASP ZAP
  • State, local and tribal government cloud servicesnot OWASP ZAP
  • Contractors processing controlled government datanot OWASP ZAP

OWASP ZAP

  • Adding a baseline security scan to every application's pipeline where per-target commercial licensing would limit coverage to a handfulnot Azure Government
  • Manual penetration testing that needs an intercepting proxy, request replay and fuzzing without a paid licence per testernot Azure Government
  • Teaching developers what an attack against their own endpoint looks like, using a tool they can install themselvesnot Azure Government
  • Pre-release regression scanning of an internal application that would never justify a commercial DAST subscriptionnot Azure Government

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Azure Government

  • Restricted to US government entities, their solution providers and contractors handling government data, with Microsoft validating eligibility first
  • A narrower service catalogue than commercial Azure
  • New features arrive later than in the commercial regions
  • Pricing is not published and runs through federal contract vehicles such as JWCC, GSA and NASA SEWP

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.

Answered from the vendors’ own pages

Azure Government: How is Azure Government pricing determined?

Azure pricing follows a pay-as-you-go model where you only pay for services you use. Prices vary by product, region, and usage patterns. Committed use discounts and reserved instances can save up to 65% for compute services.

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.

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.

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.

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.
